HDPE plumbing fitting

In the water supply and drainage piping system, plastic pipes have gradually replaced traditional pipes such as cast iron pipes and galvanized steel pipes as the mainstream pipes. Compared with traditional pipes, plastic pipes have significant advantages such as light weight, corrosion resistance, low water flow resistance, energy saving, simple and rapid installation, and lower cost, and are favored by the pipeline engineering community. At the same time, with the rapid development of the petrochemical industry and the continuous advancement of plastic manufacturing technology, the output of plastic pipes has increased rapidly, and the types of products have become more diversified. Moreover, plastic pipes have achieved great development and improvement in the design theory and construction technology of buildings, and accumulated rich practical experience, which has promoted plastic pipes to occupy a very important position in the construction of water supply and drainage pipeline engineering. Form an unstoppable development trend. In our country, the more plastic pipes used in water supply pipelines mainly include pvc-u water supply pipes, pp-r pipes, aluminum-plastic composite pipes (pap), steel-plastic composite pipes (sp), hdpe pipes, etc. The hdpe tube has only appeared in the market in the last two or three years. It is formed by hot extrusion using advanced production technology and technology. It has the characteristics of corrosion resistance, smooth inner wall, low flow resistance, high strength, good toughness, and light weight.
