Four-hole grid tube 2.2mm_ professional production of four-hole four-hole grid tube grid tube has good physical and mechanical properties, and safe and reliable health performance, four-hole grid tube is mainly characterized by light weight, high strength, acid corrosion , compression, construction convenient, with the characteristics of the material along with the province next to understand its high density process control it. Because concrete drain leakage caused environmental pollution is the biggest drawback of concrete pipes, and excellent sealing performance double wall connection socket four-hole grid tube, internal pressure can reach 0.15MPa not leak, according to statistics in the city sewage concrete pipe leak in the pipe network up to 30%, mainly because of tightness in ensuring concrete pipe with relatively poor, but also in the construction process, can not guarantee no leakage, as uneven settlement can be buried in soil can cause seal connection damage at. Four-hole grid tube during construction can be fully realized socket type flexible connection method, solves the problem of sealing the connection of large diameter plastic pipes are generally difficult to solve. And connect the internal pressure seal test I produced all double wall socket pipes all meet 0.15Mpa more. The above description is the four-hole grid tube, I hope for your help.
