The connection between chemical plastic-lined steel pipes is the most important issue in the building materials industry. Users, design, construction and other units are concerned about unreliable connection strength, inconvenient installation and maintenance, and the ability to adapt to poor natural conditions. Using the principle of cold extrusion, the inner rib pre-embedded plastic-lined steel pipe is stretched to a certain distance from the pipe end to form a small arc groove. Then insert the stainless steel snap ring of the circlip into the groove, set the nut or the expansion joint, the new enamel pipe fitting and its accessories. Quick-tighten installation. Because the matching part of the snap ring adopts the conical self-locking design and the end-diameter bidirectional sealing design, the connection strength is reliable and leakage resistant. At the same time, since the structure of all pipe joints is detachable, and special live pipe fittings are used, maintenance is very convenient.
Chemically lined steel pipes are not only used for conveying fluids and powdered solids, but also for the manufacture of mechanical parts and containers. Lined with plastic steel pipes to make space trusses, columns, and mechanical supports, it can reduce weight and complete industrial mechanized construction. Therefore, the quality of the lined plastic steel pipe is very important. The use of plastic-lined steel pipes for highway bridges not only saves steel, simplifies construction, but also greatly reduces the area of protective coatings, saving investment and maintenance costs. The lined plastic steel pipe is closely related to the development of the national economy and the improvement of the quality of human life, and is far superior to other steel products.
