The One-step PERT pre-insulation pipe production line independently developed by Qingdao Huashida Machinery Co., Ltd. Achieves high-speed stable production and ensures high-quality pipe output through the optimization of the power system's adaptability and the precision sizing of molds.
This equipment is compatible with both flexible and rigid pipes, as well as plastic-coated and steel-plastic composite processes. Its core technology originates from the introduction and localization innovation of European technology, and it has been officially recognized as the first (set) of technical equipment in Shandong Province.
Currently, the products have been successfully exported to countries such as Russia and Kazakhstan, while also serving domestic clients in regions including Ningxia, Liaoning, Shanxi, and Henan. The trial run of the project in Tieling, Liaoning Province, was completed successfully, enabling continuous production of pipes across various specifications. This significantly enhances the construction efficiency and quality of heating pipeline projects, achieving a dual improvement in both social and economic benefits.
