PE water supply pipe

product description   

The PE water supply pipe is formed by extrusion of HDPE polymer material. At present, the internationally accepted classification method is to classify pipes and their raw materials according to the long-term hydrostatic strength of PE pipes, generally three grades of PE63, PE80 and PE100. The PE water supply pipe produced by Liangcheng Technology is an eco-friendly hydrocarbon, non-toxic, odorless and non-fouling, which can guarantee the safety evaluation standard of “Drinking Water Distribution Equipment and Protective Materials for Drinking Water” and “Drinking Net” The Water Quality Standard is better than other water supply pipes and is the material of choice for water supply projects. The PE pipe is buried in the ground and is a concealed project. According to the specific requirements for pipeline construction and acceptance in the Technical Specifications for Village Water Supply Engineering, before the installation of the pipeline, quality inspection should be carried out one by one, and the internal debris and surface dirt should be removed. When installing the pipeline, check whether it is reasonable to connect, whether the joint is leaking or the pipe is damaged. Before the trench is buried, all pipelines are required to be inspected and accepted, mainly to check the specifications and types of the pipes used, whether the pipeline installation is standardized and reasonable, and whether the trench depth meets the requirements. After the installation of the water distribution pipeline is completed, a hydrostatic test is also required to see if it meets the water pressure requirements. Through the quality supervision and construction acceptance of the pipe, ensure that the project works well and better realize the benefits.

After many years of research and development and application, Liangcheng Technology has matured its technology in PE water supply pipe production equipment, raw materials and technology. From raw material procurement to product quality control methods, it has a complete ISO standard. Complete product specifications: the nominal outer diameter can be produced from 32mm to 1200mm, which can meet various water supply needs. The product has good corrosion resistance, is buried in the ground without being corroded, no scaling, no pollution, smooth inner surface, low fluid resistance and long working life. Without taking any anti-corrosion treatment measures, it can still reach the operating period of more than 50 years.

PE pipe connection

Hot melt butt joint method

The two end faces of the two tubes perpendicular to the axis of the tube are brought into contact with the heating plate to be heated and melted. After the heating plate is removed, the melting end is quickly pressed and the joint is cooled to connect the tubes. This type of connection eliminates the need for fittings and must be connected to the butt welder. The connection steps are as follows: clamping tube → milling joint surface → heating end surface → removing heating plate → docking → holding pressure, cooling.
