Polyurethane insulation pipe products are widely used, but now our life can not do without the use of polyurethane insulation pipe products, why is this? Because in our daily life, the pipes conveying water and other media are often used in polyurethane insulation pipes.

Polyurethane insulation pipe welding needs to pay attention to:

1, first of all, in the construction, to prevent the immersion of groundwater and rainwater. If the joint is accidentally immersed in water, it should be dried before welding.

2, polyurethane directly buried insulation pipe is divided into the finished product and bare pipe, finished steel pipe has been completed in the factory insulation layer and anti-corrosion layer, so welding must be prohibited direct contact with the flame, to prevent the insulation layer and anti-corrosion layer damage; And the bare pipe can be directly welded, and then do insulation and anticorrosion layer. General manufacturers will find professional and technical personnel to do the anticorrosion layer and insulation layer after welding.

3. After welding the steel pipe interface, a pressure test should be carried out on the pipe to ensure the tightness of the welded joints. After the sealing performance test, anti-corrosion treatment should be carried out on the welding points. Because most polyurethane insulation pipes will be buried in the ground after completion, so as to ensure the anti-corrosion and insulation of insulation pipes.
