Jwell Machinery provides production lines with different material formulations such as CPVC, UPVC, PVC-UH, PVC-M, PVC-O and can design single-layer and multi-layer pipe production equipment according to different uses of pipes.
Jwell Machinery provides production lines with different material formulations such as CPVC, UPVC, PVC-UH, PVC-M, PVC-O and can design single-layer and multi-layer pipe production equipment according to different uses of pipes. The production line adopts superwear resistant alloy screw barrel and chrome plated high polishing mould with fast production speed,which makes the material easy to form, plasticize uniformly, with stable operation and convenient control.
Two or three layer PVC pipes can be co-extruded by using 2 or more than 2 sets of twin screw extruders.The middle layer of the pipe is made of high calcium PVC or PVC foaming material.

Biaxially oriented polyvinyl chloride (PVC-O) pipes are manufactured through a special orientation processing process, which involves axial and radial stretching of PVC-U pipes produced by extrusion. The PVC long chain molecules in the pipes are arranged in a regular manner in the biaxial direction, resulting in a new type of PVC pipe with high strength, high toughness, high impact resistance, and fatigue resistance. Its performance is far superior to ordinary PVC-U pipes. The research and development of PVC-O pipes can greatly save raw material resources, reduce costs, improve product performance, and have significant economic and social benefits.
