Brief Introduction to Fiber Reinforced Braided Winding Pipe (BWFRP Pipe)

Fiber Reinforced Braided Winding Pipe, also short for BWFRP Pipe, is a new-type fiber-reinforced composite conduit mainly made of alkali-free glass fiber and thermosetting resin matrix.

1. Manufacturing & Structure

It adopts an integrated continuous production process: online fiber braiding + cross winding + pultrusion curing.The pipe wall features a three-layer composite skeleton:

• Inner cross braided fiber layer

• Middle longitudinal & hoop winding reinforcing layer

• Outer cross braided fiber layerMulti-directional fiber layout evenly distributes stress and greatly improves ring stiffness and impact resistance.

2. Core Advantages

1. Super insulation & flame retardant: Zero electric conductivity, ideal for power cable protection; self-extinguishing and heat-resistant.

2. Outstanding anti-corrosion: Resist acid, alkali, salt and underground chemical erosion, no rust like steel pipes.

3. Light weight & high strength: Much lighter than steel, easy for transportation and trench installation.

4. Smooth inner wall: Low friction loss, no cable scratching during threading.

5. Long service life: Stable performance underground for over 50 years, far longer than PVC, MPP or coated steel conduits.

6. Easy construction: Cuttable, flexible connection, low construction cost.

3. Main Applications

Widely used as underground cable protection ducts:

• Urban power grid, highway & railway cable engineering

• New energy charging pile, municipal reconstruction

• Communication optical cable laying

• Chemical plant, irrigation and drainage pipelines

Short Version (For product listing/RFQ)

Fiber Reinforced Braided Winding Pipe (BWFRP) is high-performance composite cable conduit produced by integrated braiding, winding and pultrusion technology with glass fiber and resin. It features excellent insulation, corrosion resistance, high ring stiffness and long service life, widely applied in underground power and communication cable protection to replace traditional plastic and steel pipes.
