PE pipe material

Welding method for PE pipes:
1. When welding PE pipes, align the axis lines of the two pipes and first weld the ends of the two pipes in place.
2. The flange should be perpendicular to the centerline of the pipe, and the surfaces should be parallel to each other. The flange gasket should not protrude into the pipe. The bolt specifications for connecting the flange should match the flange, and the length of the protruding nut of the screw should not exceed 1/2 of the screw diameter.
3. When the wall thickness of PE pipes is above 5mm, the groove should be cut to ensure sufficient welding penetration. Groove forming can be achieved through gas welding cutting or groove machine processing, but slag and iron oxide should be removed and polished with a file until a metallic finish is exposed.
4. When cutting PE pipes, the cutting surface should be perpendicular to the centerline of the pipe to ensure the concentricity of the welded pipe.
5. When welding PE pipes to flanges, the PE pipes should be inserted into the flanges first, spot welded, aligned with an angle ruler, leveled, and then welded. The flange should be welded on both sides, and the inner welding should not protrude from the sealing surface of the flange.
6. When welding PE pipes, the pipe joints should be cleaned of floating rust, dirt, and grease.
7. The flange gasket should be selected according to the drawings and specifications. Rubber gaskets are used for the cold water system, and asbestos rubber gaskets are used for the hot water system.
