China wholesale FRP Pipes and Fittings for Ship Building - Piping System – Jrain Detail:
Fiberglass pipes include pure fiberglass pipes, sand pipes, insulation pipe, dual laminate pipe (with PVC, CPVC, PE, PP, PVDF, etc.) and so on
The wall construction of a fiberglass pipe system consists of three layers:
1. Liner: determines the optimal resistance to the medium.
2. Structural layer: provides high mechanical strength and resistance to loads.
3. Top coat: protects the piping system from weather, chemical penetration and UV radiation.
They are very popular in many industries because of the below advantages:
1. An ability to be tailored for a wide variety of corrosion resistant conditions
2. Light weight (less than 20% of steel, 10% of concrete)
3. Excellent strength to weight (stronger than steel on an equal weight basis)
4. Low coefficient of friction (>25% better than steel)
5. Good dimensional stability
6. Low thermal conductivity
7. Low long-term maintenance costs
Many different joint methods are available for fiberglass pipes such as butt joint, spigot and bell joint, flange joint, lock joint and others.
Typical process flow of fiberglass pipe includes:
1. Wind mylar, spray resin and wind surface mat;
2. Make liner and liner’s cure;
3. Add the mixing stuff or resin and mortar (depend on design) to increase stiffness;
4. Make the hoop and helix winding to meet the longitudinal and hoop requirements;
5. Cure the pipe with far infrared rays;
6. Cut and grind the pipe’s ends to make the bell and spigot joint (depend on joint method);
7. Extract the pipe from mandrel with hydraulic device;
8. Hydrostatic test for pipe. If qualified, release the pipe.
