Xinxiang sewage pipe steel double-wall corrugated pipe manufacturers enhanced PE spiral corrugated steel pipe with a U-shaped steel with composite PE material, so that the pipe at no additional cost under the premise of a substantial increase ring stiffness, in the case of the same weight ratio Pipe, Carat tube strength greatly improved, to resolve overloading and other issues, large-diameter steel pipe advantage is more obvious, we now produce pipe diameter from 300mm diameter to diameter 2400mm, ring stiffness remained at 12.5KN / m or more, compared with cement pipes and other plastic pipe lighter, and more powerful. PE spiral corrugated steel pipe performance enhancements are listed below: Item Index SNB> = 8 ring stiffness SN12.5> = 12.5 KN / M2 Sn16> = 16 impact performance, TIR> =% 10 peel strength (20 + -5 degrees). N / cm> = 70 ring flexibility without rupture, opening between two walls without opening the oven no delamination crack test the tensile strength of> = 1460 creep rate = 1460, the connection does not destroy the State-run New Materials pipe fittings series: ultra high molecular weight polyethylene pipe, tailings management, processing pipe, PE water supply, drainage, sewage, irrigation pipe, float, lined with plastic pipes, rubber lined pipe, etc. Contact: Li Tel: 0379-60692511 Mobile: 130-1474 -1272 QQ: 2778205341 E-mail: 2778205341@qq.com Fax: 0379-65260950 high wear tube: http: //www.grcggc.com/ just lined pipe: http: //www.60692521.com/
