HDPE fused pipe is a plastic pipe that is connected by melting the pipe through hot-melt technology. It is widely used in construction, decoration, water treatment, chemical industry, and other fields. The hot-melt pipe has the advantages of a reliable connection, corrosion resistance, and environmental protection, and is currently the most widely used plastic pipe.
The main functions of HDPE fused pipe include:
The main use of an HDPE fused pipe is to transport liquids such as water and gas. Due to its corrosion resistance, pressure resistance, and non-deformation, it is widely used in indoor and outdoor water supply and drainage, floor heating, radiators, solar energy, and other pipeline systems. Especially in the field of construction, hot-melt pipes have become an indispensable part of new residential buildings and the renovation of old houses.
Connection principle
The working principle of HDPE fused pipe is to heat the end face of the pipe or pipe fitting to a certain temperature through a heating tool, and then keep it under controllable pressure for a certain period of time to fuse the two end faces into one, forming a pipe welding joint that meets quality requirements.
Specifically, the process of HDPE hot melt connection includes the following steps: Heating: Use HDPE pipe fuser to heat the end face of the pipe or pipe fitting to a certain temperature, usually around 210℃ (the specific temperature is determined according to the parameters provided by the manufacturer, generally between 190℃ and 240℃). Hot melt: The heated end faces are closely contacted to melt the material. Cooling: Keep it under a certain pressure for a period of time to make the molten material fully fuse and form a solid joint. During the hot melt connection process, the following key parameters need to be paid attention to: Heating plate temperature: It needs to be controlled within a certain range to ensure that the end face of the pipe melts quickly and to avoid material degradation due to excessive temperature. Welding pressure: The pressurized heating pressure is equivalent to the molten butt pressure, ensuring that the end faces of the pipe are all in contact with the heating plate and are evenly heated.
Curling height: Measures the time that the heating pressure acts on the pipe cross-section to ensure the effect of pressurized heating.
Endothermic pressure: Prevents the pipe from rebounding, improves the heating effect, and reduces the heating time.
HDPE (high-density polyethylene) is a highly crystalline, non-polar thermoplastic resin with excellent resistance to most household and industrial chemicals, but some oxidants and solvents will cause chemical corrosion to it. Therefore, when selecting and using HDPE hot-melt pipes, care should be taken to avoid contact with these chemicals.
Product Features
HDPE fused pipe has many advantages, including light material, high strength, and good toughness. It is integrated with the pipe after welding and has good impact resistance and earthquake resistance. It also has good corrosion resistance, no scaling, a smooth inner wall, and a low friction coefficient, which can increase the flow rate of the medium, increase the flow rate, and save power consumption. HDPE hot-melt pipe is made of high-quality raw materials and has a long service life, low cost, and low investment. Compared with metal materials, it can reduce about one-third of the project investment, and the project cost is affordable. Easy installation and connection, high construction efficiency.
