This Ф300-Ф3000mm HDPE steel band reinforced spiral pipe integrates the corrosion resistance of plastics with strong toughness of steel. It offers such characteristics as high ring stiffness, high reliability, light weight, easy installation, wonderful sealing performance, low-cost transportation and construction, strong corrosion resistance, and extremely strong load capacity, among others. It is a new type pipe vigorously promoted by the national and local administrative departments.

As underground drainage pipe, our HDPE steel band reinforced spiral pipe can be widely applied in the gravity transportation of different corrosive or non-corrosive media, such as urban sewage, industrial sewage, rainwater, water source, agricultural irrigation, as well as the sewage from bridges, culverts, and roads, among others. With a broad market prospect, this pipe is the first choice product for the national key construction projects. It must lead the trend of our Chinese underground drainage pipe.

Pipe Connection Methods
Connection methods of this HDPE steel band reinforced spiral pipe is mainly divided into five types, including butt fusion welding type, socket type, thermal shrinkable sleeve type, electric melting band type, as well as stainless steel loop type.
