After the PE pipe is installed, why not use gas pressure test instead of water pressure, we can get the reference index of PE pipe welding work: welding temperature: 220 degrees ± 10 degrees, so. Heating time: 9-12 seconds for pipe wall thickness. Product thickness, PE pipe here is mainly to identify product durability and manufacturing technology. The product thickness must be within the standard range, and there is not much difference in different cross-sectional thickness tests.

Humidity will affect the use effect of the materials used in PE pipes during production, so the materials used are generally dried before use, so that some factors that affect its use can also be reduced when making PE pipes. According to the pipeline planning and use, if there is a problem with the welding of the butt joints, there will be very likely to leak during the subsequent transportation process, and even the pipe fittings will break.

PE has excellent resistance to most domestic and industrial chemicals. Moreover, the low-temperature impact resistance of PE pipe is very good, and the low-temperature embrittlement temperature of polyethylene is low, so it can be used safely in the temperature range of -60-60°C. Convenient connection PE pipes mainly use thermal fusion connection and electrofusion connection to integrate the pipeline system; and have good water hammer pressure resistance, welded joints integrated with PE pipes and PE pipes’ ability to resist underground movement and end loads .

The molten material in the PE pipe welding work is cooled down on the inner surface of the sizing sleeve and forms a layer of agglomerated surface layer to ensure the accurate outer diameter of the pipe and ensure the stability and normal traction and extrusion of the pipe. Therefore, the structure and processing of the sizing sleeve are cooled.
