Variety of specifications, models, and materials for sleeve joints

    There are various specifications, models, and materials for sleeve joints, among which plastic and traditional materials are different. The pace of technological progress is faster, and the continuous emergence of new technologies, materials, and processes makes the advantages of plastic pipes more and more prominent compared to traditional materials. Compared with traditional metal and cement pipes, plastic pipes have a light weight, generally only 1/6-1/10 that of metal pipes. They have good corrosion resistance, impact resistance, and tensile strength. The inner surface of plastic pipes is much smoother than that of cast iron pipes, with low friction coefficient, fluid resistance, and can reduce water transportation energy consumption by more than 5%. Overall, they have good energy conservation, reduced manufacturing energy consumption by 75%, convenient transportation, simple installation, and a service life of up to 30-50 years. Polyethylene pipes have developed rapidly in various countries in the past decade. Polyethylene pipes are not only widely used to replace traditional steel pipes, cast iron pipes, etc., but also to replace PVC pipes.
