Double-wall corrugated pipe is made by corrugated pipe machine. The corrugated pipe wall section is double-layer structure, the inner wall is smooth and flat, the outer wall is equidistant arrangement with trapezoidal hollow structure of the pipe. Nominal diameter (DN): the nominal diameter of the pipe, which is divided into two types: inner diameter series and outer diameter series.
Corrugated Pipe Machine line is composed of two high-efficiency single-screw extruders, imported ratio-adjusting valve,double-passage spiral composite extrusion molds, vertical forming machine, spray cooling tank, double-blade radial cutter and stacker. features stable extrusion.
