Plastic pipe welding machine is a device specially used for connecting plastic pipes. It uses thermoplastic connection method without any adhesive, filler or solvent. It melts and connects the contact surfaces of two plastic pipes together by heating and applying pressure to form a strong connection. This welding machine is suitable for a variety of plastic materials, including but not limited to PE, PP, etc.
Working principle
The working principle of a Plastic pipe welding machine is to melt and fuse the fusion interface of two pipes together by heating and pressurizing. This mechanical equipment uses high temperature and pressure to melt the contact surface of the plastic pipe quickly, and after applying a certain pressure, it fuses into one. When the heating and pressurizing process is over, a certain pressure is maintained for a few seconds to solidify the welded part, thereby forming a strong molecular chain to achieve the purpose of welding. The strength of this welding method can be close to the strength of the raw materials, ensuring the reliability and durability of the connection. Plastic pipe welding machine is suitable for connecting plastic pipes. Through its specific heating and pressurizing mechanism, it can effectively connect two or more plastic pipes together to form a continuous fluid transmission channel. It is widely used in plastic pipe connection work in the fields of water supply, drainage, natural gas, etc.
PE pipe welding machine category
1. PE pipe hot-melt butt welding machine: specially used for welding PE pipes, including manual PE pipe butt welding machine, hand-cranked PE pipe butt welding machine and hydraulic PE pipe butt welding machine. These welding machines are suitable for larger diameter PE pipes, and the outer diameter of the PE pipe that can be welded is usually above 75mm. PE pipe hot-melt butt welding machines are divided into different models, such as 160, 200, 250, 315, 450, and 630, corresponding to the welding needs of PE pipes with different outer diameters. Large-diameter PE pipes generally use semi-automatic PE pipe hot-melt butt welding machines, while HDPE Gas Pipe construction requires the use of fully automatic PE pipe hot-melt butt welding machines.
2. Manual hydraulic hot-melt welding machine: This is a manually operated welding machine suitable for application scenarios that require manual operation. It is usually used for welding of smaller diameter pipes, and the operation is relatively simple, which is suitable for some specific construction environments or small projects.
3. Fully automatic hot-melt welding machine: Compared with manual operation, the fully automatic hot-melt welding machine can realize automatic welding and improve work efficiency. This welding machine is suitable for large-scale production or occasions requiring efficient welding.
4. Electric fusion welding machine: In addition to hot-melt butt welding machines, there are also electric fusion welding machines, which use electric current to pass through HDPE Electrofusion Fittings generate heat energy so that the outer surface of the PE pipe melts to achieve the purpose of welding. This welding machine is suitable for some specific welding needs.
