In the field of pipeline manufacturing, Huashida Company stands out with its one-step PERT pipe production line, leading the industry to a new height.
As an advanced manufacturing technology, the one-step method is applied to Huashida PERT pipe production line, showing extraordinary strength. The production line can continuously inject the inner pipe of PE-RT or PE material and polyurethane foam mixture into the filling area, then cover the film, and wrap the polyurethane insulation layer with an outer protective pipe to complete the production process in one go.
Its pipe diameter covers a range of 20 mm to 110 mm, and it can easily handle both hose and hard pipe insulation production. Compared with traditional technologies, the one-step method has significant advantages. On the one hand, it reduces the density of the filling foam and the wall thickness of the outer protective pipe, saving a lot of costs for pipe manufacturers; on the other hand, it realizes automated production, is not limited by the length of the insulation pipe, and greatly improves production efficiency. Moreover, the produced polyurethane foam insulation hose can be directly buried and laid, with small grooves, excellent mechanical properties, strong sealing and corrosion resistance, and the working pipe is not oxidized, and it is also very convenient to transport and store.
It is worth mentioning that ordinary extrusion equipment is difficult to meet the needs of one-step production. Huashida Company has invested a lot of energy in the special design of the screw and barrel of the extruder, the pipe mold, and the sizing cooling system. After years of overcoming 130 technical difficulties, it has successfully created the first domestic one-step PERT insulation pipe production line with independent intellectual property rights, and the whole line technology has reached the international leading level. Huashida has also become the only professional plastic machinery company in China to produce such production lines, providing comprehensive solutions for pipe manufacturers, helping enterprises to develop efficiently in the field of pipeline production, and opening a new chapter.
