An Electric junction box is an enclosure of two or more wires carrying an electrical current that protects electrical connections, maintains solid connections and provide a safety barrier to prevent fires.
Electric junction boxes are majorly recommended as it is not feasible to run a wire from every outlet or switch back to the main service panel as placing so many wires at one place can be difficult and dangerous. Junction boxes have made this task easy and also has reduced the risk that comes with the use of excessive wiring. Another benefit of electric junction boxes is that it becomes easy to detect and repair any electrical problem in a building as junction boxes are protective, easy to find and easily accessible.
Electric junction boxes are either made up of metal or plastic and come in various shapes like they can be round, square or octagonal and sizes that can be used for different purposes. An electric junction box is constructed by keeping a few things in mind like there has to be a box for receiving and connecting electrical conductors, a mounting flange connected to the box, attachment of box to an exterior layer with a round hole of construction panel, mounting clips on flange which are shaped to extend through the thickness of exterior layer of construction panel.
There is a variety of purposes for which different junction boxes are used. Some junction boxes are simply used to protect the connection of multiple wires and have a flat plate covering it while some electric junction boxes are used for wall switches, some are used for hanging ceiling fixtures and some electric junction boxes are made for retrofit work while some are specifically made for new construction. Various types of electric junction boxes that can be used for domestic purposes are round pan metal electrical box, round pan plastic electrical box, Octagon metal electrical box, Octagon plastic electrical box, Ceiling fan-rated metal electrical box, ceiling fan-rated plastic electrical box and 4-inch square box.
In a building, some electrical connections are made without the protective box i.e. junction box like in hidden ceiling, attic locations or inside wall cavities. But these junctions are not safe or reliable and can arise future problems so it is recommended that every building, house or home should use an electric junction box for safe and reliable electrical connections.
Though fiberglass is a sturdy material that resist chemicals and water, yet it can be cracked. FRP gratings India suppliers bring many ways to repair such cracks of fiberglass in this post. Read this article and know the best treatments for your FRP cracks.
Stress cracks, hairline cracks, and spider cracks in the decks of older boats are common. At times, they are hardly cosmetic, i.e. they don’t penetrate the gel coat and sometimes they penetrate deeper and harm an underlying laminate. Such scenario involves expensive repairs, so it makes sense to locate all address all suspicious-looking cracks of your boat sooner. You must consider checking the areas that feel a little spongy.
A note from manufacturers of FRP products-
Several inexpensive products are available in the market today that purposely intended to fix hairline and other fractures in fiberglass laminates. You can try them for minor repairs.
For creepy crack curing, you can try the following ways-
• Determine the cause of cracks first. How big is the crack? Where the crack locates? Do the crack surrounds an area that feels just a bit spongy?
• Toughen the laminate that has cracks by solidifying it, either by thickening with extra fiberglass, adding structures, or replacing coring materials. If you ignore this step, new cracks will start to appear sooner.
• Once you have expelled all hardware, toerails, and other paraphernalia that may interfere or clutter, break out a Dremel tool using conical bit. Use the highest speed to avoid damaged path. Dremel will do its job and give you cleaner and precise results.
• As soon as you channel out the cracks, wipe the surface with a solvent such as acetone. Take a plastic putty knife, flush-fill it with gelcoat matched to the surrounding area color, polyester filler or polyester resin and fiberglass strands.
You can mix up a small batches of gelcoat to get the approx. colour as you need. You can even use epoxy as an alternative to polyester in some situations. However, it tends to be harder than poly and you find it complex to sand smooth and finish. Do remember to layer all gelcoat repairs with plastic film because gelcoat cures in the absence of air.
• Fix the crack with final finishing. Use good wax or polish for best results. When dealing with epoxy or polyester repair, you will find several cracks, and you may require paint job of some kind in future.
You can always approach the near FRP gratings India suppliers and get the repairing services done in the presence of professionals.
If you are planning to buy composite cable trays for your facility, you should follow these advises and maintain these sophisticated yet robust products to avail their uses for years.
Packing and handling of composite pipes by professionals
• Straight lengths of ladders, trays, channels, and covers
These composite products should be packed in bundles and for this, you can use banding. Make sure you use non-metallic bonding to avoid rust stains development over galvanized products and prevent contamination of stainless steel products.
If the products’ length is more than five meter and all of them are packed in bundles, you must check that they all should be supported with at least three timber bearers for sufficient clearance to accommodate the forks of a forklift truck. Make sure that bearers shall be spaced evenly along the bundle length.
Boxed and bagged parts
Bags and boxes should be stacked over right sized pallets for handling using a fork lift truck. Pallets must be kept away from moisture and stacking should be avoided.
Tray and ladder fittings
Small fittings should be stacked oversized pallets for handling using forklift truck. You need to wrap each pallet to secure the parts. Large parts should be packed and conveyed in the same way as straight lengths.
Specialized packaging for rough handling
Such packaging type is recommended where delivery involves transshipment. In this type of packaging, the products are packed in timber crates or cases.
Loading and offloading recommendations
Site deliveries should only be made where suitable mechanical handling equipment availability is present on site. The delivered product should be treated with care. For lifting job, call experts.
Offloading with crane should include use of lifting beams that should be inserted from side to side below the bundle. The length should be sufficient to avoid undue pressure over the edge of the bottom components.
For storing composite cable tray systems, cable ladder systems and other support systems safely and sustaining them in good condition, you must follow storing tips shared by experts here-
• You can store non-metallic systems outside without cover
• The storing place should be protected against water or moisture
• The storing place should have proper drainage
You must remember these advises and store and handle your FRP cable trays and other composite systems like professionals. This guide is made by FRP cable trays manufacturers to explain how they do packing, handling, and storage of their products.
FRP products offer significant environmental benefits. In this article post, FRP pipes exporters will explain how FRP products contribute to environment and how they are considered to be sustainable products?
Components and equipments made of FRP materials offer major environmental benefits due to their characteristically low weight, great mechanical properties, and superb corrosion resistance feature. FRP composites applied in automotives can reduce overall weight by 40% as compared to steel. This is one of the solid reasons why majority of automotive manufacturers use composite body parts.
The lifecycle of FRP makes the material superior
FRP is corrosion resistant and thus, life expectancy of FRP products is eternal and never-ending. The lifecycle of FRP makes the material special and above steel and aluminum.
Even truck manufacturers avail FRP benefits
Commercial vehicle manufacturers were the first group in the automotive sector to leverage the benefits of FRP as a structural material for making truck cabs and air deflectors. Each kilogram saved in the weight of a automotive cab means a kilogram increase in payload carrying capacity.
Engines are becoming greener
FRP composites are best environmentally attractive alternative to metals. FRP material meets all the mechanical strength requirements needed for engine oil sumps and valve covers. FRP materials produce lesser noise and can resist harshest weather conditions. The engine warms up at faster speed and reaches operational efficiency sooner.
Wind farms are becoming a significant feature on land and offshore across the globe. Windmill blades are made of FRP today because steel blades will be so heavy that can be move with hurricane force only. But this is not the case with FRP blades. They are lighter in weight and can be moved easily with little pressure of air.
Can FRP become a sustainable solution?
The environmental benefits of FRP composite are proven. Issues that affect the industry are:
- Emission of volatile organic compounds
- Health and safety
- Energy consumption
Even today, people are installing FRP products at their home. Ranging from FRP doors to FRP piping, everything is available at the manufacturing outlet. FRP doors are becoming popular for new buildings and home renovations. They bring additional security to your home since they are super strong and break resistant.
If you need FRP pipes or any other product, you can any time contact FRP Pipes Exporters today. There are several suppliers available in the market engaged in delivering best quality FRP piping solutions.
Since people across the world are aware of the side effects of plastics, they have limited its use in routine life. Organizations and companies manufacturing products are using different materials to produce more eco-friendly products. FRP pipes exporters are among those manufacturers who are contributing to environment by producing eco-friendly batches of items like FRP pipes and handrails. FRP is not a plastic and it doesn’t harm environment like plastic. Fiber reinforced plastic material is completely other thing and you will be glad to find its major benefits.
Plastic waste is harmful and brings toxicity to the environment. However, plastics are not inherently bad and they possess many redeeming ecological features. Moreover manufacturers of plastic are using techniques in their design to aim for optimum use of plastic products.
Their durability and low maintenance reduce need for material replacement. The light weight makes shipping easy and cost effective. The formulation of plastic into glue products lets manufacturers to create engineered lumber and sheet products by recycling wood. The feedstock of plastic is majorly derived from natural gas or petroleum.
Toxic chemical release during plastic production is another critical source of negative impact on environment. Carcinogenic, hormone-disruptive and neuro-toxic chemicals are common ingredients and waste products of plastic production. These chemicals find their way to enter into our eco system and pollute the land, water, and air.
A few familiar compounds are vinyl chloride, dioxins (both are in PVC), benzene (in polystyrene), phthalates and other plasticizers (in PVC and others), BPA (in polycarbonate), and formaldehyde. Most of these compounds are persistent organic pollutants containing high levels of toxicity.
Disposing the plastic is a great liability
Since plastic is resistant to decomposition, you cannot dispose it because natural organisms have a tough time breaking down the synthetic chemical bond in plastic. Only 10% of the produced plastic is recycled by companies effectively and the rest is sent to landfills.
FRP products manufacturers are bringing the change in the industry by including the use of FRP materials for producing distinct range of products. The use of FRP is not limited to the making of FRP pipes and plumbing components, but it can be also used for wastewater management and other industrial applications.
FRP never corrodes and this is why you don’t need frequent replacement of FRP products. They are initially robust and durable. FRP pipes exporters understand that production of plastic will put bad impact on environment and so they are using fiberglass for various production.
Fiberglass-pressure adsorbers are resistant to several chemicals. FRP storage tank manufacturers use FRP-series liquid phase adsorbers where corrosion is their sole concern. These units have 150 psi rating that reveals that these can be used in high pressure applications. You must protect your FRP vessels from vacuum conditions by using vacuum breaker in the line.
Manufacturers intend FRP series tanks in several sizes to handle a comprehensive range of liquid flows. They craft the filament wound vessels with an internal bladder wrapped in fiberglass, which made them ideal product for filtration. They use activated carbon, resins, or other filtering media to design the filters. Food grade internals are standard along with vast variety of inlet/outlet sizes.
Installation of FRP adsorbers in the tanks
FRP adsorbers are transported empty along with the required carbon. Experts should connect the adsorbers and test all fittings pressure to determine leak points before installing the carbon through the top access hole.
A vacuum relief device is used to prevent damage in the tank. Once the carbon is loaded, clean water should be released to the unit through the bottom collector. Experts recommend backwashing the carbon to remove the carbon fines that may result in excessive pressure drop through the unit.
All liquid phase adsorbers work great when they are backwashed periodically. Backwashing removes the fines and channel flow. Apart from this, extra maintenance can be done by testing the effluent quality and checking the operating pressure of the system will help in achieving great results. Experts always recommend monitoring the containment level into the last unit to safeguard the unit against failure.
Over time adsorber’s carbon is saturated by dirt and contaminants. It is advisable to take off the unit and replace the saturated carbon with fresh one. You can easily get a fresh carbon from the store of supplier, who is already offering related products.
When preparing the unit for service, drain the water as much as possible from the vessel. Bring experts to service your tank and those who can install the carbon to it.
FRP storage tank manufacturers would like you to note down a thing- wet activated carbon expels oxygen from air. This causes a severe hazard to workers inside carbon vessels. It is necessary to put confined space/low oxygen procedures prior entering to the vessels. All guidelines should be followed by the team for best results.
GRP pipes and fittings are prepared from special resin and glass fiber reinforcement along with additives to acquire a composite structure and bring the most satisfactory product for industrial clients. GRP pipes in India are manufactured by engineers according to the specifications shared by their potential clients. Engineers are manufacturing GRP pipes with an unrestrained joint or a restrained joint where no thrust blocks are engaged at the change of directions. The pipe construction and the joints are different for both loading conditions.
Manufacturers keep the things simple and prepare all pipes and fittings with minimal initial specific stiffness. All these products are ideal for use under pressure as the experts test the entire range prior releasing to the market for industrial use.
The process of making GRP pipe
All pipes and fittings made of GRP material are manufactured by using a continuous filament winding process along with an advancing mandrel. At times manufacturing units also use dual filament winding method. They intend the internal surface of the pipes with smoother and resin rich finish. The amazing thing that every user of GRP pipes can freely use these products as the internal and external surfaces of pipes are free and clean from defects like bubbles, cracks, tackiness, voids, and foreign matters, etc.
The type of resin they use is of an unsaturated resin that offers the corrosive resistance to the products. The resin used for intending structural wall of the pipes and fittings is a polyester type containing styrene as the polymer monomer. However, they also use other types of resins depending on the application.
They don’t use pigments.
All fittings like tees, reducers, bends, junctions, and more are tested by higher authorities before releasing the product in the market.
We often use different products depending upon our needs. Some are for exterior uses and some play their role from behind. Pipes are one of those products which are used both in exterior as well as interior use. We use pipes for irrigational methods, sanitations, water supply and etc. Each type of pipe caters to different purposes.
• FRP Pipes – Glimpse
With its high demand the pipe manufacturers all over the world has always tried to develop some new type so that the use of normal pipe can be further enhanced. With this the birth of FRP (Fiberglass Reinforced Plastic) Pipes took place which are that form of pipe which are manufactured with the help of reinforced plastic. Fiberglass has mis of Silicate, polyester resin and thermoplastic which gives it ample amount of strength and durability.
• Manufacturing Process of FRP Pipes
The manufacturing of FRP pipes is done with immense care and precautions so that they may fulfil the requirement for which are used. These FRP pipes are manufactured in furnaces in which silicate, limestone, clay and other essential components are melted so that each mix and gel in with each other, this whole process is called as Pultrusion. This mix is then kept to cool down which is then eventually finished and moulded in different pipe shapes and sizes.
• Salient Features of FRP Pipes
Its features are behind the increase in demand of FRP pipes, some of the important features are given below:
=> All Weather: FRP Pipe Manufacturers always manufacture these pipes keeping its multi-use in consideration. These pipes are used in both exterior as well as interiors therefore FRP pipes are manufactured with all-weather features. They are manufactured with plastic reinforced which provide it the stability in high heat and always makes them perfect when used in water.
=> Corrosion Free: Corrosion leads to cracks and leakages. With fiberglass strength FRP pipes are always free from any effect of corrosion. FRP pipes don’t get crack and therefore chances of any leakage is minimal.
=> Coating: Style plays a vital role in success of any product. FRP Pipe Manufacturers produce FRP pipes in different colours such as white, grey, black and even transparent. As these pipes are used in both outer and inner fittings they suit the colour of the structure. The colour coating doesn’t just add to the looks but also provide strength and durability.
• Main Uses Of FRP Pipes
As mentioned earlier FRP pipes are multi-purpose and are used in many ways. Some of the major uses are discussed below:
=> Underground Sanitation: FRP pipes are mainly used in manholes to carry out the wastage safely. These FRP pipes can easily be turned with the help of reinforced elbows specially designed so that pipes can be fitted according to the structure.
=> Water Cooling Towers: Water cooling tower works with both cool and hot water. Its main agenda is to cool the heated water from the industrial use. FRP pipes are specifically fitted in these water cooling towers because they doesn’t gets affected with flow of hot water from it. It don’t get leak with passing of hot water.
=> Septic Tanks: Another use of FRP pipes are that they are used in septic tanks. These tanks usually carry harmful chemicals which can be really hazardous. FRP pipes are perfect to store and carry them safely so that these chemicals can be efficiently disposed.
You may think what is the need to paint FRP pultruded gratings or any other FRP based product. Fiberglass is often susceptible to water incursion and UV damage. It’s all depend on the type of the resin used for manufacturing the product. Epoxy resin gets weaker with time when exposed to sun. Polyesters are subject to water infiltration and vinyl esters are less strong than epoxy.
Water incursion causes blistering or bubbling, but this damage doesn’t develop instantly, it takes years. When you notice blistering for the first time, you should take serious step to fix it and especially when you are having FRP boat.
Sunlight, with epoxy resins will cause the composite to crumble and this is really bad.
What is industrial coating?
Paints are used by manufacturers of FRP products to add extra protection against UV rays and water. In the business terms, such coatings are known as industrial coatings. Premium industrial coating offers a protective layer against these things. Apart from the protection, this coat also makes the product look good.
Manufacturers use two types of coatings for fiberglass products. They are both polymer based. One coating uses exposure to air for curing and other a temperature, catalyst, and air. Air cured paints are usually polyesters that need the one-part that comes in a single container. Catalyst-cured paints are epoxies that need a catalyst and right temperature range.
Any resin based paint can be used for FRP products, however, experts recommend using epoxy-based paints on epoxy based FRP products and polyester based paints on polyester based FRP products. In simple words, epoxy paint bonds best on epoxy FRP and polyester paints on polyester FRP.
If your product is a FRP boat, you should use epoxy based coating as it is more robust and can withstand water damage. As long as epoxy is protected from sunlight, it will remain strong and flexible. The pigments n epoxy based paint will offer UV protection to the FRP product. If you are using epoxy based objects outside, you must cover it with fabric or tarp for additional protection against UV rays.
You can avail these coatings from the paint and hardware shops. If you need expert assistance to coat your FRP pultruded gratings, you can get in touch with the service providers. Experienced professionals know how to perform painting and make the product life longer. Connect with experienced professionals to avail best maintenance services.
Since manufacturing of fiber glass involves use of huge plants and furnaces, experts bring some environmental regulations for fiberglass manufacturers that may impact their business. In this post, you will read about these regulations and how manufacturers deal with them.
Since manufacturers use styrene in most production methods for fiberglass manufacturing, it causes hazardous air pollution that makes it difficult for life to breathe at excessive levels.
Solution- The gelcoats containing less styrene can be used instead to emit less air pollution.
Experts issue permits to handle the amount of pollution that exhales into air by the factory plants. If the manufacturers use an average of 40 gallons of resin and gelcoat together in a day, they will need an air permit.
Wastewater and polluted runoff affect the river and groundwater. Due to such pollution, potable water becomes unsafe for use, pollutants kill the marine life, and water bodies become unfit for swimming as well.
Is a permit needed for manufacturers for water quality?
Yes, water quality permit is a must for manufacturers if wastewater or wash water release to dry wells, surface water, or storm drains. They need to check with the sewage treatment plant prior discharging to the sewer. This is necessary for process water.
Industries need a storm water permit if manufacturing materials are exposed to storm water and the runoff enters a point source discharge like a ditch or storm drain.
Other than these, all drywells and sumps have to be registered and approved prior to use via underground injection control program.
When manufacturers make use of solvents, it can generate dangerous waste that can degrade environment if not properly managed. The only solution to this is that they should create useful products to prevent formation of hazardous waste.
The regulations of hazardous waste include labeling, record keeping, and handling requirements.
How to manage this hazardous waste?
Remember that specific requirements rely on the status of quantity produced. Manufacturers must-
Determine if the produced waste is hazardous
Learn how to measure it
Measure the waste to know the generator status
Keep hazardous waste in closed containers
Label and date your waste containers
Meet storage time limit restrictions
In this way, fiberglass pipe manufacturers deal with environmental regulations to produce minimum pollution and make environment friendly for life.
