Huashda technology innovation launched one-step spraying and winding insulation pipe production line

In response to the industry's demand for high-efficiency insulation pipe equipment, Qingdao Huashida has launched a one-step spray winding insulation pipe production line. This production line adopts high-load spiral transmission and integrates processes such as pipe rust removal, polyurethane spraying, and polyethylene winding to achieve continuous production, solving problems such as low efficiency of intermittent production and weak load capacity of traditional continuous production. It produces pipe diameters ranging from 508 to 1880mm, insulation layer thicknesses from 30 to 120mm, with a daily output of 2,200 meters. It features a high degree of automation, energy conservation and low consumption. The independently developed online mixing foaming and automatic spraying technologies have reached the leading level in China, filling many domestic gaps and being widely applied in centralized heating, oil and gas transportation and other fields.
