FRP Drainage Pipe

FRP Drainage Pipe

The Jinyang FRP (Fiberglass Reinforced Plastic) drainage pipe is a corrosion-resistant buried pipe designed for sewage, stormwater, and industrial effluent drainage. With high ring stiffness, smooth hydraulics, and flexible watertight joints, it provides a long-life solution for gravity and pumped drainage where concrete or metal pipes corrode or scale.

How It Works

The pipe is filament-wound with a corrosion liner and a stiff structural wall, often with a sand-filled layer for buried stiffness. Wastewater enters through the inlet and flows by gravity or under pump pressure to the treatment point. Rubber-ring joints seal the pipe while allowing slight ground movement without leakage.

Key Features

• Corrosion resistant - resists aggressive sewage, chemicals, and soil, avoiding concrete decay and metal rust.

• High ring stiffness - buried pipe withstands earth and traffic loads without collapse.

• Smooth hydraulics - low-friction interior maintains high flow capacity and reduces blockages.

• Watertight joints - rubber-ring couplings prevent exfiltration and groundwater ingress.

• Light weight - faster installation and lower handling cost than concrete or ductile iron.

• Long service life - designed for decades of buried service with no maintenance.

Technical Options

Diameters DN300 to DN3000, stiffness classes SN2500 to SN10000, non-pressure or low-pressure ratings. Bends, tees, reducers, and inspection chambers available.

Typical Applications

Municipal sewage and stormwater, industrial effluent drainage, road and airport drainage, agricultural drainage, and mine dewatering.
