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.

I appreciate the emphasis on the different phases, from raw material selection to the final product inspection. It's evident that a meticulous approach is taken to ensure the quality and durability of FRP pipes. The incorporation of fiberglass and resin in the manufacturing process showcases the innovative techniques used in the industry.
