Simply put, steel pipe pickling is the process of cleaning steel pipes with an acid solution to remove surface impurities such as oxide scale (the black oxide layer formed during high-temperature forging), rust, and oil, exposing a clean and bright metal surface. This process is crucial for subseque

Steel pipe surface treatment is a crucial process determining its corrosion resistance lifespan and coating adhesion; its quality can influence the final product's lifespan by up to 50%. The core objective is to remove surface contaminants, obtain a clean surface, and form a suitable roughness (anch

Steel pipe sandblasting is a process that uses high-speed abrasive impact to clean and roughen the surface of steel pipes. Its core purpose is to remove rust and scale, and to provide adhesion for subsequent anti-corrosion coatings. It is often the most critical step in pipeline anti-corrosion proje

I. Main FunctionsPermanent Pipe Sealing: Primarily used for welding or threaded connections at the ends of pipes, completely sealing the pipeline and preventing media leakage. Unlike removable blind flanges, once welded and installed, it is usually permanent.Temporary Protection During Transportatio

The core reason for using beveling on steel pipes is to ensure weld quality, especially when the pipe wall is thick. Simply put, beveling involves machining a groove of a specific geometric shape at the end of the steel pipe to be welded, creating the necessary conditions for a high-quality weld.The
