    We can see that the PE pipe is used in a large amount around us and has its own unique advantages, so we must master its welding method. How many welding methods does it have? It will be introduced in the next article.
    1. Hot melt butt fusion Hot melt butt fusion uses a hot melt butt welding machine to heat the pipe end, after the pipe end melts, quickly attach it, maintain a certain pressure, and achieve the purpose of welding after cooling.
    Any size larger than 90mm can be connected by the hot-melt butt joint process. This method is economical and reliable, and its interface has higher strength than the coffin itself under tension and pressure. 2. Saddle-type butt joints are often encountered in the application process. According to the actual needs, the problem of main pipe tapping, the traditional and pipe must first cut off a section of the main pipe, and then install a tee to complete the tapping. The saddle-shaped tee can be connected by butt connection, that is, a saddle-shaped butt welder is used to directly connect a saddle-shaped tee on the main pipe, and then the equipped cut-to-cut main pipe is used to bend into a main pipe tap. The construction is very Fast.
    3. Steel-plastic flange connection pipes and steel pipes and valves should be connected by steel-plastic flanges. The pipe end and the corresponding plastic support ring can be connected by hot-melt butt joints. The connection between the steel pipe end and the metal flange should comply with Corresponding to the regulations of steel pipe welding, then flange plates can be used to bend the connection with the steel pipe.
    The flange connection is also suitable for the mutual connection between two pipes. Generally speaking, no seal ring is needed between the support ring and the support ring, but in large size and high pressure working conditions, it is still necessary to add a seal ring. When flanges of other materials are used for flange connection, sealing rings must be used.
    The welding method of PE pipe is introduced above. We can use the above method for welding in the future. If you have a purchase request, you can contact us.
