Two types of welding process:
Ultrasonic overlap welding, co-extrusion forming.
Butt-joint argon-arc welding, welding seam close-gained and smooth.
High automation, Adopting PPC programmable computer control system
Closed loop controls automatically the process of the speed of extruding and hauling, temperature and product diameter.
One machine multipurpose may simultaneously produce different PE, PP, PP-R, PE-RT pipe
