HDPE connection fittings, especially HDPE hot-melt fittings, are an indispensable component of PE pipe connection. After these fittings are heated to the melting point, they can achieve connections with different requirements such as the same outer diameter, different outer diameters, tees, bends, etc.
Function of HDPE connection fittings
The use of HDPE connection fittings ensures the reliability and durability of HDPE pipe systems in various application scenarios.
In addition, the application of HDPE fittings has also expanded to a wider range of fields, including urban tap water supply, rural water supply, and industrial water supply.
These fields have high requirements for the safety, durability, and environmental friendliness of water supply systems. HDPE water supply pipes have become the preferred material in water supply systems due to their high-strength material and the advantages of resisting external pressure. Its excellent pressure resistance and corrosion resistance can ensure the safety of drinking water for urban residents, and also adapt to the complex terrain and harsh climatic conditions in rural areas, providing farmers with clean drinking water and farmland irrigation water.
In the industrial field, HDPE water supply pipes can meet the large water supply needs of chemical, petroleum, metallurgical, and other industries, and undertake important water supply tasks.
Types of HDPE connection fittings
The categories of HDPE connection fittings mainly include electric fusion connection, hot melt connection, groove connection, flange connection, screw gland connection, and fixed gland connection.
Electric fusion connections and hot melt connections use heating to melt the ends of HDPE pipes, and then the pipes and fittings are connected by pressure or mechanical means. Both methods require the use of professional equipment and tools, such as electric fusion welding machines and hot melt welding machines, to ensure the firmness and sealing of the connection.
Groove connection is to cut grooves on HDPE pipes, and then use ABS compression rings (clamps) and C-type EPDM rubber rings for flexible connection. This connection method is suitable for occasions that require quick installation and disassembly.
Flange connection and screw gland connection realize the connection of HDPE pipes by flanges and screw glands. Both methods provide high connection strength and sealing and are suitable for occasions that need to withstand a certain pressure.
The fixed gland connection is achieved by fixing the gland and rubber ring on the socket end of the pipe fitting, and then inserting the pipe into the socket end to achieve a flexible socket connection. This connection method is suitable for occasions that need to withstand a certain pressure and have telescopic functions.
The choice of connection method mainly depends on specific engineering requirements, pipe size, and material factors. Each connection method has its specific application scenarios and advantages, so when choosing, it is necessary to comprehensively consider various factors to ensure the reliability and safety of the connection.
