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
