Drainage Pipe Series

The full name of hexagonal pipe is high-density polyethylene ( HDPE-IW)hexagonal structure wall pipe , and the outer wall is an annular corrugated structure , which is a new type of sewage pipe . The ring stiffness exceeds 50 kN , and it is suitable for use environments from 60 ° to minus 60 ° C , and has excellent resistance to environmental stress cracking and crack propagation . The service life is up to 70 years , the bottom of the pipe is more compact , the  groove is in contact with the pipe surface , and the backfill has no dead ends.

A-type tube: HDPE hollow wall winding pipe type A is a structural wall pipe made mainly fro- m high-density polyethylene ( HDPE) through a special winding molding process. This type of pipeline has a unique " I-shaped" structure , with flat inner and outer walls and a structural wall in the middle, representing thecharacteristic characteristics of hollow wound pipes.

B-type tube: HDPE winding structure wall B-type pipe is a new type of irregular structurew-  all pipe made by high-density polyethylene hot winding forming process . It has the characteristics of long service life , high resistance to external pressure ,g-  ood connection , no leakage , environmental protection and no pollution. HDPE winding structure wall B-type pipe was initially introduced by domestic enterp- rises from the German Kra company, and is therefore commonly referred to as  Kra pipe in China .
