Fusion weld pipe fittings are a connection method that heats the pipe or pipe fitting to a molten state and then connects them together by applying pressure. This connection method is widely used in plastic pipes, such as polyethylene (PE) pipes, and other non-metallic pipes. The methods of fusion weld pipe fittings mainly include hot melt connection and electric fusion connection.
Connection method difference
Hot-melt connection: This is a connection method between non-metal and non-metal after heating to the melting point. The specific operation includes inserting the outer surface of the pipe and the inner surface of the pipe fitting into the die head of the welder without rotation for a few seconds, then quickly removing the welder, quickly inserting the heated pipe into the pipe fitting, maintaining pressure, and cooling to complete the connection. Hot-melt connection is widely used in the connection of new pipes and fittings such as PP-R pipes, PB pipes, PE pipes, metal composite pipes, and curved elastic vector aluminum alloy lined plastic composite pipeline systems.
Electrofusion connection: This is a plastic (polyethylene) pipe fitting that is melted and connected by the temperature generated by an electric current. Electrofusion Fitting is recognized as one of the best connection methods for polyethylene pipes. Its main advantages are that it can greatly reduce the influence of human factors in the welding process, obtain high-quality connections, high strength, long life, good airtightness, easy operation, and high construction efficiency. Electrofusion connection is suitable for the connection of gas pipelines.
Both connection methods heat the pipe or pipe fitting to a molten state and then connect them together by applying pressure or current to form a firm connection. They are widely used in various plastic piping systems, ensuring the safety and reliability of the piping system.
Advantages of Fusion weld pipe fittings
1. High connection strength: Fusion weld pipe fittings fuse the pipe fittings with the pipe through the temperature generated by heating or current to form a firm connection. Its connection strength is usually higher than other connection methods, which can ensure the stability and safety of the pipeline system.
2. Simple operation: The process of fusion welding is relatively simple, does not require complex operating steps or professional skills, and makes the installation process more convenient.
3. Safe and reliable: During the fusion welding process, due to the simple operation and high connection strength, the possibility of leakage or other safety hazards in the pipeline system during use is reduced.
4. Low cost and high efficiency: The installation cost of fusion welding is relatively low. At the same time, due to its simple operation, it can significantly improve construction efficiency and reduce overall costs.
5. Stable quality: The quality control of fusion welding is relatively easy. Through standard operating procedures and quality control measures, the quality consistency of each welding can be guaranteed, thereby improving the quality stability of the entire pipeline system.
6. Wide range of applications: Fusion weld pipe fittings are suitable for a variety of materials, such as PE pipes, PPR pipes, etc., and are widely used in water supply systems, heating systems and other fields.
Fusion weld pipe fittings occupy an important position in the field of pipeline connection due to its unique advantages and are the preferred connection method for many engineering projects.
