Product features

Corrosion resistance and wear resistance of steel skeleton plastic (PE) composite pipe

the steel skeleton plastic (PE) composite pipe is a kind of crystalline non-polar material used in steel skeleton polyethylene plastic composite pipe. Its chemical property is very stable, it can resist the erosion of various chemical media, and has no electrochemical corrosion. Its wear resistance is four times that of steel pipe.

Hygienic properties of steel skeleton plastic (PE) composite pipe

the hygienic index and safety of steel skeleton plastic (PE) composite pipe are in line with GB9687-1988 Hygienic Standard for Polyethylene Molded Products for Food Packaging and GB/T17219-1998 Safety Evaluation Standard for Drinking Water Transport and Distribution Equipment and Protective Materials respectively.

Smooth inner wall, low conveying resistance of steel skeleton plastic (PE) composite pipe

the steel skeleton plastic (PE) composite pipe adopts the internal shaping process, its inner surface is smoother than the inner wall of the steel pipe, the absolute equivalent roughness is 0.01 mm, while the steel pipe is 0.2 mm. The transportation capacity under the same conditions is obviously higher than that of the steel pipe. At the same time, the inner wall of the pipe is smooth and wear-resistant, the transmission resistance is small, no scaling, no waxing, and the long-term operation has obvious energy-saving effect.

Long-term hydrostatic strength of steel skeleton plastic (PE) composite pipe

According to ASTM D2837, D1598 and D1599 standards, BROUTMAN Laboratory in Chicago, USA, tested the long-term hydrostatic strength of steel skeleton plastic (PE) composite pipe. the results show that the creep resistance and damage resistance of steel-framed polyethylene-plastic composite pipes are much higher than that of polyethylene-plastic composite pipes of the same size at 23C60C\80C.

Comparison of Rapid Cracking Performance between steel skeleton plastic (PE) composite pipe and PE pipe

Rapid cracking resistance and environmental stress cracking resistance of steel skeleton plastic (PE) composite pipe

Because of the existence of annular wire mesh, the radial load bearing capacity of composite pipe is greatly improved, which improves the anti-rapid cracking and environmental stress cracking performance of the plastic pipe wall of composite pipe. the Belgian BECETEL pipe fitting research center, according to the ISO13477 (S4 test) standard, tested the fast cracking resistance of DN steel skeleton plastic (PE) composite pipe. the results showed that the steel skeleton plastic (PE) composite pipe had excellent anti cracking performance.

Impact resistance and dimensional stability of steel skeleton plastic (PE) composite pipe

the elastic modulus of steel is usually about 200 times of that of HDPE. Due to the reinforcement of steel skeleton, the rigidity, impact resistance and dimensional stability of steel skeleton PE-plastic composite pipe are better than any other plastic pipe. At the same time, the structural characteristics of the reticulated steel skeleton make the composite pipe retain moderate flexibility in the axial direction. Therefore, the pipe has the characteristics of both rigidity and flexibility. It is not only convenient to transport and install, but also can effectively bear the longitudinal load caused by soil settlement or sliding, surface vehicles and so on, and has good operation reliability.

Traceable of steel skeleton plastic (PE) composite pipe

Because of the existence of metal mesh in steel skeleton polyethylene plastic composite pipe, the composite pipe has inherent traceability. It can be traced by magnetic metal detector without additional tracing or protection marks. It can effectively avoid Excavation Damage and provide great convenience for safe operation, emergency rescue and maintenance.
