BWFRP pipe

Fiberglass braided wrapped reinforced plastic cable conduit

BWFRP (Fiber Braided Pultruded Pipe) consists of an inner braided layer, an intermediate layer, and an outer braided layer. It is continuously composite through fiber braiding, impregnation, and fiber pultrusion, and is suitable for use as protective sleeves for power cables and communication cables. The industry standard was released in 2017. The product consists of an inner woven layer, an intermediate layer, and an outer woven layer, which are formed through a pultrusion process. The ideal composite material product is composed of inner and outer woven layers designed at different weaving angles, as well as longitudinal and circumferential composite intermediate layers. This new type of cable conduit product has advantages that traditional pipe materials cannot match.

Advantages

High ring stiffness, impact resistance, and settlement resistance

The BWFRP pipeline is formed by interweaving high-performance fibers horizontally and vertically to enhance the ring stiffness of the pipeline from a physical structure perspective, which can resist damage caused by external pressure and foundation settlement

High tensile strength

>The weaving angle of BWFRP pipes reaches 120 °, using an inner and outer three-layer weaving process, with high tensile strength and significantly improved flexibility compared to traditional pipes.

Smooth inner wall and convenient cable threading

The inner wall of the pipeline is smooth and easy to thread cables. Rubber sealing rings are installed at the beginning and end of the joint to adapt to thermal expansion and contraction, effectively preventing mud and sand from entering.

High corrosion resistance and water resistance

BWFRP pipes are extruded under high temperature and high pressure, with high product density and superior water resistance. They are made of high-performance epoxy resin and alkali free glass fiber raw materials, which have higher acid and alkali resistance than traditional pipes.

High electrical insulation

By selecting excellent alkali free fibers and high-performance epoxy resin for molding under high pressure conditions, the density of BWFRP pipes is increased by 35% compared to traditional pipes, with no bubbles and high insulation.

Lightweight pipes, easy transportation and installation

Adopting a direct connection method, the weight is lighter under the same wall thickness, reducing transportation pressure, making installation convenient, and significantly shortening the construction period. To avoid prolonged exposure during road excavation, which may affect urban traffic order

Superior thermal conductivity

Under the same ring stiffness, BWFRP pipes have the thinnest wall, excellent thermal conductivity, better current carrying capacity, and lower electrical losses, thereby enhancing the service life of cables.

Good resistance to high and low temperatures

WFRP pipelines have anti freezing and high temperature resistance properties, can adapt to harsh environments, and remain undamaged and non deformed in extreme temperature states of -50 ℃ to 200 ℃, still possessing high-quality and good toughness.

Superior flame retardant performance

BWFRP pipes have superior flame retardant properties, with an oxygen index greater than 28, exceeding national standards, and will not be ignited at all when the pipe encounters fire.

Safety and Environmental Protection

The main raw material for BWFRP pipes comes from quartz (stone), and the raw materials extracted from the stone are returned to the ground, fully in accordance with natural laws and passing the strict environmental testing standards of the country and the European Union.
