Specific steps for PE hot melt welding equipment
Dec 01, 2018

The main function of PE hot-melt welding equipment is to dock the pipe of PE water supply pipe and gas pipe. It can select the appropriate clamp fixture according to the welded pipe and pipe fittings, and clamp the pipe to prepare for cutting. The welded pipe section, the end face impurities and the oxide layer of the pipe are cut to ensure that the butt joint faces of the two pipes are smooth, smooth and free from impurities.

 

When PE is hot-melt welded, it is necessary to ensure that the end faces of the two welded pipes are completely centered. The smaller the wrong side, the better. The wrong side cannot exceed 10% of the wall thickness, which will affect the quality of the butt joint. And the docking temperature is generally between 210-230 ° C, the heating plate heating time is different in winter and summer, the melting length of the two ends is preferably 1-2 mm.

 

When the PE is hot-melted, the heating plate should be removed, and the two hot-melt end faces are quickly adhered and pressurized. To ensure the welding quality, the switching cycle is as short as possible. Hot-melt butt joint is the key to welding. The docking process should always be carried out under the melt pressure, and the width of the crimping should be 2-4mm.

 

In the cooling process of the PE hot-melt process, it is necessary to keep the butt pressure constant, let the interface cool slowly, and the cooling time is long and the hand is hard to touch, and the heat is not felt. After the docking is completed, release the lining, remove the docking machine, and re-prepare the next interface for welding.www.wuxibaodamachine.com
