What are the rust removal methods of 45# seamless steel pipes

The surface treatment of the 45# seamless steel pipes is one of the key factors that determine the anti-corrosion service life of the 45# seamless steel pipes. It is the premise of whether it can be firmly combined during the anti-corrosion construction process of the oil and gas pipelines. In addition to the type of coating, coating quality and construction environment that affect the life of the anti-corrosion layer, the surface treatment of 45# seamless steel pipes has an impact on the life of the anti-corrosion layer. The surface treatment of the 45# seamless steel pipes should strictly follow the requirements of the anti-corrosion layer specification.

1. Cleaning
Remove oil, grease, dust, lubricants and similar organic matter, etc.

2. Pickling
Removal of oxide scale, rust, and old coatings, sometimes used as reprocessing after sandblasting and rust removal.

3. Derusting tools
Remove loose oxide scale, rust, welding slag, etc.

4. Spray rust removal
The surface of 45# seamless steel pipes is sprayed.
