Surface Treatment Methods for Stainless Steel Guardrails: The surface treatment and cleaning of Wuxi Spiral Pipe utilize solvents and emulsions to clean the steel surface, effectively removing oil, grease, dust, lubricants, and similar organic substances. However, it cannot eliminate rust, scale, flux, and other surface impurities on the steel, thus serving only as an auxiliary method in anti-corrosion production.

The surface treatment tool for spiral pipes primarily uses wire brushes and other tools to grind the steel surface, which can remove loose or raised oxide scales, rust, slag, etc. Manual rust removal can achieve Sa2 level, while power tool rust removal can reach Sa3 level. If the steel surface is coated with firm oxide scales, the tool's rust removal results may not be satisfactory, and the anchor pattern depth required for anti-corrosion construction may not be achieved.

Wuxi Spiral Pipe Surface Treatment: The acid pickling process is commonly done using both chemical and electrolytic methods. Pipeline anticorrosion only employs chemical acid pickling, which can remove oxidation scales, rust, and old coatings, and can sometimes be used as a secondary treatment after sandblasting. While chemical cleaning can achieve a certain level of cleanliness and roughness on the surface, it has shallow anchor patterns and is prone to environmental pollution.

The Spiral Tube Surface Treatment Spraying (Throwing) Rust Removal process involves a high-power motor driving the spraying (throwing) blades to rotate at high speed, causing abrasives such as steel sand, steel shot, wire segments, and minerals to spray (throw) against the tube's surface under the effect of centrifugal force. Not only does this method thoroughly remove rust, oxides, and impurities, but it also achieves the desired average roughness on the steel tube due to the intense impact and friction from the abrasives.

After spiral tube surface treatment by spraying or blasting to remove rust, it not only extends the physical adsorption effect on the tube's exterior but also enhances the mechanical adhesion between the anticorrosion layer and the tube's surface. Therefore, spraying or blasting to remove rust is an ideal method for pipeline anticorrosion. Generally, shot blasting (sandblasting) is primarily used for the internal and external surface treatment of tubes, while abrasive blasting is primarily used for the surface treatment of tubes.
