- The Pickling Process for Stainless Steel PipesThe pickling process for stainless steel pipes is used to remove oxide scales, rust, oil stains, iron oxides, and other impurities from the surface of the pipes, thereby making the surface smooth, improving corrosion resistance, and enhancing welding performance. The pickling process is typically caProduct knowledge January 20, 2025
- The Role of 3LPE CoatingThe 3LPE coating (Three-Layer Polyethylene Coating) is a three-layer coating system primarily used for corrosion protection of pipelines. Its functions can be summarized as follows:Corrosion Protection:The main function of the 3LPE coating is to protect the pipeline from corrosion caused by externalProduct knowledge January 14, 2025
- "Hot-dip Galvanizing" And "pre-galvanizing""Hot-dip galvanizing" and "pre-galvanizing" are both galvanizing treatment methods for metal surface corrosion protection, but their processes and applications are different: 1. Hot-dip galvanizing:Process: The steel is immersed in molten zinc liquid (usually at a temperature of about 450°C) to reacProduct knowledge January 06, 2025
- Corrosion resistance principle of stainless steel seamless pipesThe "stainless steel" in stainless steel pipes refers to a type of steel that has excellent corrosion resistance and is resistant to oxidation and rusting. This steel is primarily composed of iron, carbon, and at least 10.5% chromium. Chromium is the key alloying element responsible for the corrosioProduct knowledge December 30, 2024
