Introduction: According to the needs of customers, our company has developed a variety of expansion joints of various materials, which are widely used in various water supply and drainage, gas, chemical and other pipeline systems, which well meet the use needs of relevant projects. But a lot of customers

Our company according to the needs of customers, professional purpose products developed a variety of materials Expansion joint It has been widely used in various water supply and drainage systems. However, many customers do not understand the performance advantages of expansion joints of different materials when using the product, resulting in waste of engineering application. Our company will introduce the performance characteristics of various materials expansion joint products professionally, so as to help many special customers to master this new equipment and get better use in the project.
After more than 20 years of professional production, our company has produced cast iron expansion joint, ductile iron expansion joint, Q235 steel expansion joint and stainless steel expansion joint. The production of cast iron expansion joint is convenient, and the welding gap is relatively small. The phenomenon of weld leakage is not easy to occur in the use process. The overall molding and processing cycle is relatively short Telescopic device The main feature is that the casting performance is relatively good, and the castings with relatively complex shape can be produced in the production process, especially the valve expansion products with asymmetric shape, and the wear resistance of the expansion products is relatively good, Cast iron expansion joint The cost is relatively low, so the market is relatively broad. Ductile iron expansion joint can absorb pipeline displacement, soft ductile iron can absorb pipeline vibration and displacement. Compared with cast iron expansion joint's brittleness and high toughness of Q235 steel pipeline expansion joint, ductile iron expansion joint has a high strength under flexibility
Gland type loose sleeve expansion joint is a new type of pipe fittings designed and produced according to the construction characteristics of pipeline engineering. This product can complete the mutual connection of the pipeline. In addition to the completion of the pipeline connection, it can complete the flexible connection of the pipeline by making full use of the structural characteristics, so as to achieve the purpose of stable working state. Therefore, Luoying gland type loose sleeve expansion joint product has been widely used in various sewage treatment projects. Recently, our company's gland type loose sleeve expansion joint products have made it possible to achieve the purpose of stable working state In the sewage treatment project, the excellent performance of the product meets the needs of the project.
The gland type expansion joint products produced by our enterprise are mainly used in the sewage treatment project. The new project mainly aims at the construction of urban sewage treatment facilities and supporting pipeline network, and strengthens the supervision and management of the operation of the sewage treatment plant, which effectively improves the operation efficiency of the current sewage treatment facilities. During the construction of 2431 km wastewater supporting pipe network and the completion of the upgrading and reconstruction tasks of 11 sewage treatment plants, the gland type expansion joint products of our enterprise have well met the use needs of the said project. The owner of the community is one thing, and the enterprise's gland type expansion joint products have been further recognized.
