Hanwei has two general performance specification classes:

1. Anhydride cured FRP pipe and fittings specifically designed and engineered for extended operating use of up to 65°C
2. Amine cured FRP pipe and fittings specifically designed and engineered for extended operating use of up to 93 °C

Hanwei FRP Pipe Systems have been extensively installed in sub-surface applications. Hanwei FRP Pipe Systems used in above ground applications utilize UV stabilizers and adhesive bonded FRP saddles and/or rubber pads at pipe support points.

Hanwei provides a comprehensive range of fittings and fixtures (T's, elbows, reducers, etc) and a range of flanges for connection to existing systems. Custom fittings, fixtures and flanges can be developed specifically for our client's requirements.
