How to improve the quality of SSAW steel pipe?

SSAW steel pipes play a crucial role in protecting vital materials during media transportation, such as oil, gas, water, and heating in pipelines. To enhance the quality of SSAW steel pipes, it is essential to improve their surface preparation and anti-corrosion treatment. Here are several methods to achieve better quality.

Surface Polishing:

Use tools like wire brushes, sandpaper, or other abrasives to polish the surface of the anti-corrosion spiral pipe. This process helps remove loose scale, rust, welding slag, and other impurities.

Cleaning with Solvents:

Apply solvents or emulsions to clean the surface of the anti-corrosion spiral steel pipe. While this method effectively removes organic contaminants, it is not sufficient to eliminate surface rust, oxide scale, or flux. Therefore, cleaning with solvents serves as a supplementary technique to aid in surface preparation.

Chemical Pickling:

Chemical pickling is a crucial step for pipeline anti-corrosion. It removes rust, scale, and old coatings, while also enhancing the surface’s cleanliness and roughness to meet required standards for optimal anti-corrosion performance.

Abrasive Blasting:

A high-power motor drives spraying (or throwing) blades at high speeds, propelling abrasives like steel sand, steel shots, iron wire segments, and minerals onto the surface of the anti-corrosion steel pipe. This process, through centripetal force, effectively removes rust, oxides, and dirt while ensuring the pipe achieves the necessary uniform roughness. The impact and friction from the abrasives further enhance the quality of the anti-corrosion coating.

By employing these techniques, the overall quality and performance of SSAW steel pipes can be significantly improved, ensuring greater durability and reliability in media transportation systems.
