product description

The glass fiber reinforced plastic (polyethylene) composite pipe is made of high-density polyethylene as the inner pipe, and the high-strength glass fiber reinforced composite tape is wound on the inner pipe in the forward and reverse directions of the reinforcing layer, and the high-density polyethylene is the outer cladding layer, and A new type of pressure-resistant plastic composite pipe that is firmly combined by a special process. The large-diameter RTP composite pipe has filled the domestic gap, and the main technical performance has reached the international advanced level.

Performance characteristics

★Good hygienic performance: HDPE pipe processing does not add heavy metal salt stabilizer, the material is non-toxic, no fouling layer, no bacteria, and it solves the secondary pollution of urban drinking water.

★Resistant to wear and corrosion: The inner wall is smooth and the friction coefficient is small; the wear resistance is 4 times that of the steel pipe. Except for a few strong oxidants, it can withstand the erosion of various chemical media; the inner wall is not fouled, and the head loss is lower than that of the steel pipe. ~40%.

★ Long service life: Under normal use environment, the service life of buried pipeline can reach more than 50 years.

★Excellent physical properties: good flexibility, resistance to distortion, excellent impact resistance, strong shock resistance, anti-wear performance, and impact strength superior to metal tubes.

★Reliable connection performance: It adopts the connection method of hot-melt butt joint and electric hot-melt. The connection strength of the interface is higher than that of the pipe body, and the joint will not be broken due to the fundamental changes or other external forces.

★Good construction performance: light weight, density is only one-eighth of the steel pipe, the welding process is simple, the construction speed is fast, the excavation amount is small, compared with the metal pipe, the engineering cost can be reduced by one third.

★ Large conveying flow: smooth pipe wall, can increase the flow rate of the medium, increase the flow rate, and save power consumption compared with the same metal pipe.

★ Green and environmental protection: The glass fiber composite pipe is a good solution to the problem of difficult recycling of metal composite pipes. The product has no secondary pollution and can be recycled and reused.

★ Cost-effective: Compared with PE solid-walled pipe, the price of the same pressure grade is reduced by 10%, the larger diameter is more significant, and the maximum is reduced by 40%. Compared with the ductile iron pipe, the price is equivalent, but the superior physical property of the plastic is metal. Compared with the steel wire wound pipe and the steel skeleton composite pipe, the high strength and weight ratio of the continuous fiber (glass fiber) of the RTP pipe and the flexibility and anti-corrosion properties of the thermoplastic are more perfect, especially The integral solid wall is formed by lamination and full fusion, which makes the structural integrity and performance advantages more extraordinary, and solves the problem that the plastic steel does not fuse.
