Things to note when welding plastic-coated steel pipes

The wide range of applications of plastic-coated steel pipes has brought them a lot of room for development. As the demand for plastic-coated steel pipes increases, manufacturers have sprung up. The advent of a new era of plastic-coated steel pipes. As people's awareness of environmental protection continues to strengthen, coated steel pipes The plastic steel pipe industry has ushered in a new stage of rapid development. Plastic-coated steel pipes are high-quality products that are environmentally friendly, energy-saving, anti-corrosive, and flame-retardant.

For fire-fighting plastic-coated pipes, it is recommended that when welding plastic-coated steel pipes, a 150mm long light pipe should be reserved at the interface of the plastic-coated steel pipes (mainly to prevent corrosion between processes and apply high-temperature anti-rust primer), so that it will not burn out during welding. Coated with plastic film. After the welding is completed, if the quality is qualified, the welding joint and the reserved 300mm pipe end can be anti-corrosion treated by wrapping with plastic bags, shrinking tape wrapping, or flame spraying.
