Surface pretreatment of heat shrink tape
- Aug 13, 2018 -

The pipeline is in contact with the ground and the air for a long time. If the protective measures are not taken in time, it is easily corroded. The heat shrink tape can be entangled on the pipeline to prevent corrosion. How does the surface pretreatment work?

1. Remove deposits such as welding slag, burrs, grease and dirt on the surface of the steel pipe. For pipes with overheated anti-corrosion coatings, appropriate methods should be used to remove the original anti-corrosion layer and residue.

2. Use mechanical or sandblasting to remove rust, if specified sandblasting.

3. After derusting, the defects exposed on the surface of the steel pipe shall be treated. The dust and abrasive adhering to the surface of the heat shrink tape shall be cleaned, and the surface of the steel pipe shall be kept dry. When rust or surface contamination occurs, surface pretreatment must be repeated.

Some deposits are often attached to the surface of the pipe. Whether it is a heat shrink tape or a pipe, the surface should be cleaned in time to make it more resistant to corrosion and the pipe is no longer affected by the outside world.
