309S Seamless Stainless Steel Pipes Cold Rolled 20mm OD 2mm Thickness 12m Length EN Decorative Use
Stainless steel pipes generally use three Brinell, Rockwell, Vickers hardness indicators to measure their hardness. Among the stainless steel pipe standards, Brinell hardness is the most widely used, and the hardness of the material is often expressed by the diameter of the indentation, which is intuitive and convenient. However, it is not suitable for steel pipes of harder or thinner steel.
For stainless steel pipes with an inner diameter of more than 6.0mm and a wall thickness of less than 13mm, an annealed stainless steel pipe with a W-B75 type hardness tester can be used. It is very fast and simple to test and is suitable for fast and non-destructive qualification inspection of stainless steel pipes.
Stainless steel pipe fittings also known as stainless steel precision pipe fittings, also known as precision pipe. In the process of making precision stainless steel pipe fittings, whether in the surface smoothness or on the wall thickness, the tolerance range of the outer diameter, is much more accurate than the general stainless steel pipe fittings. According to the most basic standards, precision stainless steel pipe fitting accuracy can basically reach ±0.05mm-±0.15mm. Here the tolerance range of the author also briefly explain. Generally, the tolerance range of tubes with small diameter and thin wall thickness is ±0.05mm. Relatively speaking, the tolerance range of precision stainless steel pipe fittings with larger diameter is basically ±0.05mm-±0.15mm. The exterior is also very bright and can basically reach the equivalent of 150-200 mesh. The wall thickness and outer diameter of ordinary industrial stainless steel pipe fittings are basically in accordance with the specified tolerance range of plus or minus 10%. The appearance is also not smooth. Therefore, the general precision stainless steel pipe fittings and ordinary industrial stainless steel pipe fittings can basically be distinguished by the naked eye.
