Qingdao Huashida Machinery Co., Ltd., which has been deeply involved in the plastics industry for more than 20 years, has always been a leading enterprise in the application of PERT (heat-resistant polyethylene). It has continuously explored and developed how to better utilize PERT (heat-resistant polyethylene), and has achieved a number of national and provincial scientific research results. It plays an important leading role in the manufacturing and production of continuous flow-coated PERT pre-insulated pipe production lines.
Taking 2022 as an example, the output of prefabricated direct buried insulated pipes in my country reached 23.95 million meters, with a market size of 31.06 billion yuan, and the demand increased to 23.471 million meters, of which 87.30% were municipal heating pipes. For the world, the market size of Thermal pre-insulated pipes in 2022 is about 11.7 billion US dollars, of which PERT pipes are 1.3 billion US dollars. Faced with such a huge market cake, many customers at home and abroad hope that a PERT pre-insulated pipe production line with leading technology and process can be born. It is in this reality that Huashida's one-step flow coating PERT pre-insulated pipe production line came into being.
