The pipe wall structure consists of three levels: the inner layer is a continuous solid wall inner layer pipe, which is then wrapped between the inner and outer layers of hot-melt polyethylene with spiral steel ribs pressed into an approximate "U" shape by a continuous steel strip. The high strength of the steel and the flexibility, corrosion resistance, and wear resistance of the polyethylene are combined together, which can achieve a ring stiffness level of 16KN/m for the pipe, making up for the limitation that larger diameter plastic buried drainage pipes can only reach SN8.

Our company strictly produces steel reinforced polyethylene (PE) spiral corrugated pipes for buried drainage in accordance with the national standard CJ/T225-2006. The new structure and scientifically reasonable forming process give the pipe a unique advantage. Compared with traditional drainage pipes, it has the advantages of reliable sealing, long service life, flexibility and earthquake resistance, light weight, convenient and fast construction, easy connection, and no leakage; Corrosion resistant and with a service life of up to 50 years, it is a new type of chemical building material with broad prospects for promotion. It is suitable for drainage pipeline projects such as rainwater, sewage, and wastewater discharge systems where the medium temperature does not exceed 45 ℃ for a long time.

• The pipe material is reinforced with steel strip, with a novel structure and high strength. It has good compressive and impact resistance, and the ring stiffness can reach 16KN/㎡.

• HDPE is a non-toxic raw material, free from secondary pollution, and not corroded by sewage, wastewater, and chemicals.

• Smooth inner wall, low friction, less prone to scaling inside the pipe, and strong water flow capacity.

• Flexible interface, good anti settlement performance, can be used in soft soil quicksand foundation.

• Easy to connect, no leakage at the joint.

• The comprehensive cost of the project is low, and the service life can reach 50 years under normal use.
