Underground for drainage steel reinforced polyethylene (HDPE) pipe continuous spiral Spiral Corrugated Pipe pressed into the approximate shape of a spiral steel ribs ^ wrapped in heat-sealed between the inner and outer layers of polyethylene, the high degree of steel steel, high strength and poly ethylene flexibility, corrosion resistance, wear together. Production diameter range 300-2200 mm, length 6-10 m, ring stiffness can reach SN8, SN12.5, SN16, SN18 four levels to make up for past large diameter plastic pipes buried in the general ring stiffness SN8 only limit is reached.
The product can be connected using a variety of methods to adapt to different project needs, to better meet the convenience of sealing reliability and connectivity construction requirements.
MRP in achieving high performance while highlighting the advantages of saving raw materials, can significantly reduce the cost than buried with full plastic ring with a diameter steel pipes.
