Stainless steel pipe characteristics introduction

Most stainless steel products require good corrosion resistance. Some foreign merchants also conduct corrosion resistance tests on the products: use NACL aqueous solution to heat to boiling, pour the solution after a period of time, wash and dry, and weigh the weight loss to determine the damage. Corrosion degree (note: when the product is polished, because the emery cloth or sandpaper contains Fe components, it will cause rust spots on the surface during the test)

Stainless steel pipes are long strips of steel, which are mostly used as pipelines for conveying fluids, such as oil, natural gas, water, gas, steam, etc. Steel pipes that are subject to fluid pressure must undergo hydraulic tests to test their pressure resistance and quality. No leakage, wetting or expansion under pressure is qualified. In addition, when the bending and torsion strength are the same, the weight is lighter, so it is also widely used in the manufacture of mechanical parts and engineering structures.

Stainless steel tubes are often used to produce various conventional weapons, barrels, and shells. Steel pipes are divided into two categories: seamless steel pipes and welded steel pipes (seam pipes). According to the cross-sectional shape, it can be divided into round pipes and special-shaped pipes. Round steel pipes are widely used, but there are also some square, rectangular, semicircular, hexagonal, equilateral triangle, octagonal and other special-shaped steel pipes.

Different product uses have different requirements for welding performance. A type of tableware generally does not require welding performance, even including some pot enterprises. However, most products require good welding performance of raw materials, such as Class II tableware, thermos cups, steel pipes, water heaters, and drinking fountains.

At present, stainless steel products generally go through the polishing process during production, and only a few products such as water heaters and water dispenser tanks do not need polishing. Therefore, this requires good polishing performance of the raw material.
