1. Hot melt butt joint:
Hot-melt butt welding is to use a hot-melt butt welding machine to heat the end of the pipe (hot-melt butt welding temperature is 210c), the end of the pipe is melted and bonded quickly, maintain a certain pressure, and achieve the purpose of welding by cooling.
HDPE pipes with a size larger than 90mm can be connected by hot-melt butt joint.
2. Steel-plastic flange connection:
When connecting with steel pipes and valves, flange connections should be used. The connection between the end of the steel pipe and the metal flange shall meet the welding requirements of the corresponding steel pipe.
PE pipe special connector
3. Saddle type butt connection:
In the application process of HDPE pipes, the problem of tapping the main pipe according to actual needs is often encountered. The saddle tee can be connected by the saddle tee can be connected by saddle butt welding, that is, the saddle butt welding machine is used to directly connect a saddle tee on the main pipe, and then the main pipe is cut with the equipped cutter, and it is completed The division of the supervisor, the construction is very fast.
4. Electrofusion connection:
The electric fusion connection is to put the electric fusion pipe fitting on the pipe first, and then use a special welding machine to energize the electric fusion pipe fitting according to the specified parameters (time, voltage, etc.), so that the inner surface of the electric fusion pipe fitting embedded with the electric heating wire and the pipe are inserted. The outer surface of the end melts, and the pipe and fitting are together after cooling. It is characterized by convenient and quick connection, good quality joints, and little interference from external factors, but the price of electrofusion pipe fittings is several times or even dozens of times that of ordinary pipe fittings (the smaller the diameter, the greater the difference).
