Painted packing steel belt reinforced polyethylene spiral corrugated pipe has a common layout, function and characteristic. The obvious characteristics of painted steel straps:
1, can reach higher ring stiffness, can complete SN8, SN12.5, SN16;
2, the bonding between the painted steel strip and the plastic inner and outer layers is strong, the pipes are corrosion-resistant, wear-resistant, site construction costs, anti-leakage, can avoid the pollution of groundwater resources, and are beneficial to environmental protection;
3. Compared with concrete pipes, the pipes are light in weight, fast in transfer and installation, and convenient in patching: convenient assembly; pipe network construction and assembling speed is fast, and patching 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), which is the same as the standard pipe, and the plastic drainage pipe can increase the water flow by 30%;
5. There are a variety of connection methods for different engineering needs. At present, extrusion melt welding, heat shrinkable tape connection and electric heating tape connection are mainly used;
