FRP pipes are being accepted across all industries including chemical, petroleum, gas, water transportation, etc. FRP is competing with materials like ductile iron, epoxy coated MS, PVC, HDPE, etc on account of its non-corrosive and long-lasting properties. FRP Pipe Manufacturers have proved the utility of piping systems in stony environments and brutal applications. FRP Pipes have wide applications in water transmission, industrial process pipeline, industrial wastes and effluents, food industries, etc.
FRP pipe manufacturing process
The manufacturing process of FRP pipe manufacturers consists of the following stages:
- Pipe composition
- Pipe specification
- Method of manufacture
- Jointing systems of pipes and fittings
The design stage consists of selection of liner and resin, design of winding patterns, design of optimization and wind ability check.
In the pipe composition stage, it is necessary to mention that the pipe wall consists of three layers which are perfectly adherent to each other. The three layers are the inner layer, the structural wall and the external line. Each of these layers have their own properties.
When we mention the pipe specifications, we can safely say that these pipes are manufactured in diameters ranging from 100mm to 2600 mm. Typically the applicability, physical and mechanical properties are laid down before the actual manufacture begins.
The FRP pipe manufacturing process undergoes the following stages:
The pipe is manufactured using the Helical Winding Method. Here, the first stage is Mandrel preparation, then the liner preparation and curing takes place. Then the filament winding and structural part of the pipe are made. Then the pipe is cured, later the pipe is extracted from the mandrel, then the final outside layer is made, after which the two sides and the end preparation is carried out.
Then the pipes are joined using various types of joints like the flanged joint, the butt and wrap joint, the bell and spigot joint and the double bell coupling. In the jointing stage, good craftsmanship and accuracy are the minimum requirements
Finally, the pipes are installed in place by referring to the installation drawing provided for the purpose. This stage is also called as the execution stage. Here the pipes are laid in place after being fabricated in a factory. The installation takes place based on the installation manual and the installation drawings.
Thus, this article has touched upon the preliminary applications of the FRP pipes and has explained the procedure of manufacture of FRP piping systems. The manufacturing process takes place in a factory and therefore it is elaborate in nature. It is accomplished using various kinds of machinery and tools. The FRP Pipe Manufacturers can be likened to the construction of a building. The different stages of manufacture mentioned above are followed in letter and spirit irrespective of the brand of manufacturer with a little difference here and there. Additionally, installation drawings and manuals make it possible to place the pipes on location accurately at the designated place. This makes an efficient piping system for transporting different fluids from one place to another.
