The one-step flow-coated PERT insulated pipe production line is a significant achievement of Qingdao Huashida Machinery Co., Ltd., which has been deeply involved in the plastics industry for over 20 years and has continuously explored, developed, and utilized PERT (heat-resistant polyethylene).
PERT insulated pipe is a complex, multi-layered pipe material, and its development has faced numerous technical challenges. Traditional production lines, mostly modified versions, suffer from numerous issues: the traditional one-step process is unsuitable for PERT, requiring only a two-step approach; multi-layer co-extrusion complicates production; it can only produce a limited number of product specifications and materials, with poor adaptability to new materials; it cannot quickly adjust parameters, resulting in limited flexible production capacity; and it lacks remote intelligent control capabilities, making it difficult to meet the remote response needs of the international market.
The plastic pipe industry is enormous. In 2022, my country's prefabricated direct-buried insulated pipe production, market size, and demand were expected to be significant. The global market for insulated heating pipes is also substantial, with PERT pipes accounting for a significant share. Faced with this enormous market, domestic and international customers are looking for leading-edge production lines. As an industry leader, Huashida's one-step flow-coated PERT insulated pipe production line has emerged as a response to this challenge.
