PE water supply pipe construction steps
PE water supply pipe construction steps
PE water supply pipes are made of special polyethylene as raw material and extruded in one step by a plastic extruder. They are used in urban water supply pipe networks, irrigation water diversion projects, agricultural sprinkler irrigation projects, etc. So what are the construction steps of PE water supply pipes during operation? Here, the editor of Desu will introduce the process to you in detail. In the construction steps of PE water supply pipes, the editor of PE drainage pipes will tell you:
1. Material preparation: Place the pipe or pipe fitting in a flat position and place it on the docking machine, leaving a sufficient cutting allowance of 10-20mm.
2. Cutting: Cut the impurities and oxide layers on the end faces of the welded pipe sections and pipe fittings to ensure that the two butt end faces are flat, smooth and free of impurities.
3. Centering: The end faces of the two welded pipe sections must be completely aligned. The smaller the misalignment, the better. The misalignment cannot exceed 10% of the wall thickness. Otherwise, the docking quality will be affected.
4. Heating: The docking temperature is generally between 210-230℃. The heating time of the heating plate is different in winter and summer. The melting length of both ends is 1-2mm.
5. Melt docking: It is the key to welding. The docking process should always be carried out under melt pressure, and the crimping width should be 2-4mm.
6. Cooling: Keep the docking pressure unchanged and allow the interface to cool slowly. The cooling time shall be determined by touching the curled edge and not feeling any heat.
7. Docking is completed: After cooling, release the slips, remove the docking machine, and prepare for the next interface connection again.
