What is the difference between precision stainless steel pipe fittings and general stainless steel pipe fittings

What is the difference between precision stainless steel pipe fittings and general stainless steel pipe fittings Precision stainless steel pipe fittings, also known as stainless steel precision pipe fittings, are also called precision pipes. In the process of manufacturing, precision stainless steel pipe fittings are much more accurate than ordinary stainless steel pipes in terms of the smoothness of the appearance, the tolerance range of the wall thickness, and the outer diameter. According to the most basic standards, the precision of precision stainless steel pipe fittings can reach ±0.05mm-±0.15mm. I also briefly explain the tolerance range here. Generally, the diameter of the pipe is relatively small, and the tolerance range of the pipe with a thinner wall thickness is ±0.05mm. Relatively speaking, the tolerance range of precision stainless steel pipe fittings with larger diameters is ±0.05mm-±0.15mm. The appearance is also very bright and can reach the equivalent of 150-200 meshes. Generally, the basic wall thickness and outer diameter of stainless steel pipe fittings are within plus or minus 10% according to the national tolerance range. The appearance is also not smooth. Therefore, general precision stainless steel pipe fittings and general stainless steel pipe fittings can be distinguished by the naked eye. Post time: May-31-2021
