Removing rust from steel pipes hinges on selecting the appropriate method for the rust severity and ensuring proper post-treatment protection. Always wear gloves, safety goggles, and a mask before starting.

For general rust, physical grinding is the most direct and effective approach. If the rust is light, manually scrub with a wire brush or sandpaper. For larger or thicker rust patches, using an angle grinder fitted with a wire wheel will save considerable effort. The goal of grinding is to thoroughly remove loose rust layers until the solid metal surface is exposed.

For complex pipe shapes or if manual grinding is undesirable, chemical methods can be attempted. Purchase a commercial rust remover, apply it according to instructions, and let it sit. It dissolves or converts the rust, after which the surface should be thoroughly rinsed with clean water. Household items like white vinegar also offer mild rust removal, but are generally only effective for very light rust.

Regardless of the rust removal method used, immediate rustproofing is essential afterward, otherwise the steel pipe will rust again more quickly. First, thoroughly clean the pipe surface with water and detergent, then dry it completely. Immediately apply rust-preventive oil or spray on specialized rust-proof paint to form a protective layer. This step is crucial for preventing rust recurrence and determines how long the rust removal effect will last.

  We plan to purchase a batch of hot-dip galvanized steel sheets. Given that our previous suppliers failed to meet our material performance requirements, we have strict standards for the corrosion resistance, galvanized layer quality, and processing performance of the sheets this time. Can you provide a detailed material certificate that meets the relevant standards to ensure that the chemical composition and mechanical properties are up to standard? Can you guarantee the bending performance? We need to confirm that when the sheet metal is processed at a specific bending radius, there will be no zinc layer peeling or micro-cracks. 18/11/2025 17:43:19
