FRP materials are used by industries to make lighter and stronger components. FRP pipe manufacturers use this material over traditional metal ones to make your world safer. They are producing fire resistant and robust piping solutions for industries. Other than piping solutions, FRP is also used in making bridges, safety barriers and acoustic screens, and crush cones. In this article, we will talk about the FRP material and the techniques used by manufacturers to process FRP.
With any manufacturing process, engineers follow certain health and safety precautions to handle and use FRP materials. They rely on some techniques like Styrene reduction techniques. In FRP moulding process, conversion of unsaturated polyester resin takes place with the use of reinforcing fibers and structural composites.
Engineers dissolve the UP resins in styrene that reacts to cross-link the polymer during curing process. Styrene acts as an effective monomer for these resins. It is the responsibility of the engineers to follow the standards and set limits issued by national authorities.
Styrene emission reduction is gained by reacting resins having lower styrene content and by blending in additives to provide lower emissions when used to the mold and left for curing process. This ensures protection against health and safety risks related to their products.
Worker safety and clothing solution
Safety of workforce is important and thus, foundry men have to wear protective clothing including gloves, goggles, coveralls, masks, and other protective equipments. All of these products can be availed at manufacturers’ shop or FRP distributors.
Do you know how manufacturers make FRP?
Three different processes are widely used by engineers to make FRP pipes. Fiber reinforced plastic pipe is made with three processes- filament winding, centrifugal casting, and hand layup. Filament winding and centrifugal castings are applied to prepare piping solutions up to approx 12 inches in diameter. Hand layup method is usually used for pipes with larger diameter and for asymmetrical shapes.
Let’s discuss these processes in detail-
- Filament winding – in this process, continuous fiberglass filaments are saturated with catalyzed liquid resin and wound across polished steel mandrels. A mechanical device is used for feeding the fibers.
- Centrifugal casting – it involves layering glass cloth on the inner tubular mold walls that is rotated at high speed. Catalyzed resin is inserted inside the rotating mold, which continues its movement while the resin cures.
- Hand layup – it is a manual fabrication method that involves building up layers of chopped glass impregnated with catalyzed resin across a suitable mold. It is used by frp pipe manufacturers for custom shapes.
