The inner-fiberglass outer-braided fiberglass tube (also known as BWFRP: Braided Wound Fiberglass Reinforced Plastic Tube) is a high-performance composite pipe made of alkali-free fiberglass and high-performance epoxy resin.
Manufactured via a continuous braiding-impregnation-pultrusion process, the tube has a 120° braiding angle for balanced tensile strength and flexibility. Key properties:
- High ring stiffness & tensile strength
- Excellent corrosion resistance & electrical insulation
- Flame retardant (Oxygen index >28)
- Lightweight & easy installation
Applications
-
Power & Communication Engineering
- Cable protection for urban power grids, subway & rail transit systems
- Communication ducting for underground networks (anti-settlement)
-
