A small box, usually made up of metal or plastic, which forms part of an electrical conduit or thermoplastic sheathed cable (TPS) used in the wiring of buildings – both commercial and residential, is usually known as an electric junction box. Why is it called a ‘junction’ box? This is basically due to the protection it provides to the connection of several wires transmitting and transferring electric current. Just similar to these boxes carrying cable wires, there are wall mounted containers which carries switches, sockets and the wires associated with these electrical components and these are called pattress. It is always advisable to consult the leading manufacturers and suppliers of electric junction boxes and related electrical components, to ensure they are built from genuine raw materials and that they are quality assured products which will be durable.
Benefits of Electric Junction Boxes
The reasons why you should get an electric junction box installed in the buildings, both residential and commercial, can be summarised as below:
Types of Electric Junction Boxes
Generally an electric junction box is made up of plastic or metal components. They are available in different shapes and sizes based on the capacity of the cables and wires carrying electricity load. The boxes which cover the cables and wires bundling have a soft plate which acts as a support to hold the box against the wall. There are also junction boxes which are used as an outlet or for wall switches, often for hanging ceiling fixtures among others. There are also customised boxes meant specifically for new construction buildings whereas there are others which are only for old ones. Get your junction box customised from the wide array of electric junction boxes by the leading manufacturers and suppliers. Consult the premium manufacturers only, so that you receive the best guidance on the shape, size and type of box your property or project requires. They will also be able to guide you on the installation and after sales services.
Say, you want an outlet for your kitchen or a ceiling fan to be installed newly by creating a new holder, or you want a new circuit, a junction box will be required. Consult the trained personnel from the leading manufacturers and suppliers, as it requires the mechanical knowhow and electricity involves danger unless careful!So contact the pioneer manufacturers and dealers and grab the boxes!
Since plastic materials are often used for storing and processing corrosive stuff like acids, the consequences of a failure can be devastating. GRP pipe manufacturers would like to share details on non destructive testing of GRP laminates through this article. How to inspect GRP laminates and how NDT tool helps in the job is explained well in this post.
Non destructive testing or NDT tool is essential for inspecting GRP pipes and tanks. Earlier, NDT methods for field use have not been completely intended for adequate precision. Today, many modern facilities are running procedures for several testing methods of GRP laminates. It includes-
It is done with a portable digital imaging unit. The results are processed instantly and evaluated in digital computer. The equipment is user-friendly and small-scale.
Ultrasonic testing is used for detecting delamination and corrosion. The structure of GRP material can make the use of ultrasound complex.
To standardize and enhance the process of visual inspection, professionals take help of tool to detect the most common defects. This allows experts to distinguish manufacturing defects from others that have been appeared during operations.
With the help of these three NDT methods, it is possible for the manufacturers to comply with available regulations, even if the component is made of GRP material.
The inspection of welds and joints is also important for ensuring safety and quality of newly commissioned plants prior taking the ownership from the owner or contractor of the site. NDT plays critical role in the inspection.

ipes like pressure pipes, sewer pipes, drainage pipes, industrial pipes, etc. are the products supplied by frp pipe manufacturers. These products are being made at manufacturing unit using Helical Winding Method. This method is most flexible one as manufacturers are able to produce different sizes of pipes at a time on the same machine. The engineers use GRP/FRP materials for production of FRP and GRP pipes. These materials are fed to computer controller winding machine. The operator starts the programme for specific pipe and the machine winds the pipe accordingly.
In this post, we will discuss different phases involved in the processing of FRP/GRP pipes.
First and foremost thing done by manufacturers is preparation of mandrel. Mandrel is cleaned and polished before its use. Once it is cleaned and polished, a thin film is wrapped across the mandrel to achieve better inner surface finish. This will help releasing of pipe smoothly and easily from mandrel.
Nin next stage, manufacturers apply a resin layer on the mandrel. After that, multiple layers of resin is being applied with glass surface mat and chopped strand mat.
During helical winding process, continuous strands of closely spaced glass fibers are wound over the cured liner with computer controlled machine. Manufacturers perform winding pattern with pre-programmed machine to achieve the required thickness in the piping.
Once the filament winding process is done, manufacturers put the mandrel for curing up to 1-2 hours. The timings depend on the weather condition.
When manufacturers are done with the curing process, the product is released from mandrel by hydraulic extraction machine.
When the pipe is removed from mandrel, a final layer of resin is applied by manufacturers with UV stabilizer.
After finishing the final layer with UV stabilizer, manufacturers cut the both rough ends of the pipe and calibrate them for coupler jointing. They prepare them for hydraulic testing and send the quality assured products to finished goods department.
These are critical phases involved in the process of manufacturing of pipes. FRP pipe manufacturers are performing every step with concentration to avoid making mistakes. If you need more information about these phases, ask your manufacturer and supplier today. To know more about FRP pipes and GRP pipes, write your requirements in comments below.
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.
No doubt traditional materials are recognized for their benefits and uses. But, the harsh, corrosive environments have made FRP gratings India as a perfect partner for all. There are several reasons that explain the interest of industrial clients in FRP gratings. We will also explain use of FRP gratings in this post. Keep reading to know about FRP gratings.
FRP composites resist a broad variety of chemicals and remain unaffected or undamaged. Painting is the only maintenance tip suggested by experts to protect the FRP composite materials against UV rays.
Steel is subject to oxidation and corrosion. You have to paint the steel surface to protect it against harsh weather conditions. Still there is no surety that there will be no damage.
Aluminium can cause galvanic corrosion.
Wood can rot, warp, decay when exposed to water, moisture, and chemicals. Wood is even prone to attack by bugs.
