Efficient Production Line for HDPE Double Corrugated Pipes
Product Overview
HDPE Hollow Wall Corrugated Pipe/Structured Wall Pipe produced by this line features high ring stiffness, high impact intensity, and low weight due to its unique structure. Additional advantages include excellent creep deformation resistance, outer pressure resistance, erosion resistance (to acid, alkali, salt, etc.), and an approximate 50-year service life.
Qingdao Huashida Machinery Co., Ltd.'s winding pipe production line incorporates the latest domestic and international technologies, capable of producing pipes with diameters ranging from 200 to 5000 mm.
This equipment is widely used for sewerage and drainage in municipal applications, effectively replacing cement pipes, cast iron pipes, and other traditional piping systems. Its low assembly cost, easy operation, simple connection, and economical construction make it highly promising with significant market potential.
Production Process
Raw materials → Mixing → Vacuum feeding → Material drying → Single screw extrusion → Calibration → Spray cooling → Traction → Single screw glue extrusion → Winding and forming → Water cooling → Cutter → Pipe bracket → Inspecting & packing
