Hangzhou Shuanglin Company held the Shuanglin PEX-b technical achievement appraisal meeting in Hangzhou on August 28. After five hours of discussions and on-site inspections, experts and professors made a comprehensive analysis of the technical solutions of Shuanglin PEX-b, and finally made a high evaluation on the technical solutions, market feasibility and product innovation. At the same time, many opinions and suggestions were put forward in terms of design and other aspects.
Silane cross-linked polyethylene (PE-Xb) pipe has excellent comprehensive properties, especially at high temperature, and its pressure resistance is better than PPR, PPB (C) and peroxide cross-linked polyethylene (PE-Xa), silane cross-linking. Polyethylene pipe has a service life of more than 50 years, which makes it the first choice for concealed projects and low temperature hot water floor radiant heating pipes. With the popularization of low-temperature hot water floor radiant heating in Northeast China, Northwest China and North China, the market capacity of PEX pipe is huge and the market prospect is promising. Domestic pipeline manufacturers introduced foreign equipment, which promoted the marketing of PEX-b pipes. However, due to the high price of imported equipment and high operating costs, many pipe manufacturers are discouraged.
The research and development of the Shuanglin one-step PEX-b production line and many successful cases have brought better choices to domestic pipe manufacturers. The maximum speed of Shuanglin PEX-b production line reaches 40m/min, the operation is stable at 37m/min, the silane consumption is 1.2～1.8%, the pipe cross-linking degree is ≥65%, the temperature control is accurate, and the error error of each zone is within ±1°C. Fully meet production needs. The production line has been tested by Zhejiang Fangyuan Testing Group Co., Ltd. and meets the Q/HSL002-2007 corporate standard. The silane cross-linked polyethylene pipe produced by the production line has been tested by the National Chemical Building Materials Testing Center and conforms to the national standard: GB/T 18992 "PE-X Pipeline System for Hot and Cold Water".
