Phases involved in production of frp pipe manufacturing

Pipes 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.

Mandrel preparation

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.

Liner preparation and curing

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.


Phases involved in production of frp pipe manufacturing

Filament winding the structural part of the pipe

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.

Curing

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.

Pipe extraction from mandrel

When manufacturers are done with the curing process, the product is released from mandrel by hydraulic

extraction machine.

Final outside layer

When the pipe is removed from mandrel, a final layer of resin is applied by manufacturers with UV stabilizer.

Preparing both ends of the pipe

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.
