1. Hot melt docking:
Hot-melt butt welding uses a hot-melt butt welding machine to heat the pipe ends (the hot-melt butt welding temperature is 210±10°C). After the pipe ends melt, they are quickly joined together, maintaining a certain pressure, and then cooled to achieve the purpose of welding.
HDPE pipes with a size larger than 90mm can be connected by hot-melt butt jointing.
2. Saddle-type butt connection:
In the application process of HDPE pipes, we often encounter the problem of main pipe tapping according to actual needs. The saddle tee can be connected using the saddle butt method, that is, use a saddle butt welder to directly connect a saddle tee to the main pipe, and then use the equipped cutter to cut the main pipe, and you are done. Competent and the construction was very fast.
3. Steel-plastic flange connection:
It should be connected with steel pipes and valves using flange connections. The connection between the steel pipe end and the metal flange should comply with the regulations of the corresponding steel pipe.
