The diameter is DN200-DN5000, and the ring stiffness is SN8-20 kN/mm2. The larger the diameter, the better the performance and cost of the product, and it can be customized according to customer requirements;  
The connection method adopts a socket double sealing ring or heat shrinkable sleeve connection, which is convenient and fast to construct, suitable for DN200-DN800 caliber; For pipelines of DN800 and above, electric heating fusion tape connection is used for safety, convenience, and high construction efficiency.
The product is composed of high-density polyethylene PE100 grade raw materials and carbon spring steel wire. Polyethylene has the advantages of high corrosion resistance, acid and alkali resistance, cracking resistance, fatigue resistance, aging resistance, and no scaling. It is tightly combined with steel wire, and the two are rigid and flexible, forming a structure where plastic tightly wraps around steel wire. The steel wire provides high ring stiffness, that is, high resistance to external pressure. The pipeline burial depth can reach 15m, and there is no problem with drainage under the main road, with extremely excellent performance.
