When stretching, jack placed horizontally in the square between the compensator arms, plus a good support and pad, stretched his arms jack starting the pre-pull closer to the required weld gap, weld alignment weld. When using trombone pull the cold front stretching ends of the fixing bracket weld compensator straight pipe with both ends of the connection between the end of the reserved 1/4 of its elongation, tensile device with a trombone. When stretching, the trombone's Kaka pulled flanged pipe weld the ends. By adjusting the wear between two flanged pipe length card stud bolts, welds pulled closer to the pre-clearance requirements for compensation, weld alignment weld. Can be carried out simultaneously on both sides of cold-drawn, can also be operated separately. Gongyi City Serco non-metallic compensation characterized mainly reflect the following aspects: production formula is reasonable; different from similar products in the market in terms of the proportion of raw materials and additives, produced by the non-metallic compensation closer to the modern business needs. Environmental protection products; environmental protection in recent years has been all over the world are vigorously advocate, steel products belong to the chemical industry, a few years ago because of production equipment behind axial compensator, expansion joint compensation technology can not keep up, leading to a lot of chemicals corporate pollution to cause great social environment. In recent years, Serco pipeline through continuous technical innovation, and explore an effective method in the production of non-metallic compensation process. Axial compensator | Serco supply material (certified) | compensation provided by Serco Gongyi City Water Supply Materials Co., Ltd. Serco Gongyi City Water Supply Materials Co., Ltd. (www.gyxjbcq.com/) is Zhengzhou, gate leader, over the years, the company is implementing the scientific management, innovation and development, the principle of honesty and trustworthiness, and satisfy customer needs.
