PE Insulation Pipe Machine

Comerise factory’s PE insulation pipe machine also called PE vacuum anti-corrosion and thermal insulation pipe production line (φ90-φ2000) is a new pipe production line developed by our factory based on foreign pipe extrusion technology and combined our years of real production experience. This series of units consists of extruder, mould, vacuum sizing box, tractor, cutting machine, unloading rack and other equipment. It has the characteristics of high automation, high production, stable performance and long service of life. It is currently the most advanced and high-quality anti-corrosion and thermal insulation pipe production line in the world.
