Features of painted steel strap

Due to the unique structure, performance and characteristics of the painted steel strap reinforced polyethylene spiral corrugated pipe, its main advantages are:
　　1. It can achieve relatively high ring stiffness, which can achieve SN8, SN12.5, and SN16;
　　2. The bonding between the painted steel strip and the plastic inner and outer layer is firm, the pipe is corrosion-resistant, abrasion-resistant, anti-leakage, can prevent the pollution of groundwater resources, and is beneficial to environmental protection;
　　3. Compared with concrete pipes, the pipes are light in weight, fast in handling, construction and installation, and convenient in maintenance: easy installation; pipe network construction and installation speed is fast, and maintenance is convenient;
　　4. The roughness coefficient of the inner wall of the pipe is 0.01 (the roughness coefficient of the concrete pipe is 0.013), and the pipe material of the same specification and the plastic drainage pipe can increase the water flow by 30%;
　　5. There are a variety of connection methods to meet the needs of different projects. Currently, extrusion melt welding, heat shrinkable tape connection and electric hot melt tape connection are mainly used;
