What is the surface smoothness of stainless steel bright annealed tube?

Stainless steel bright annealed tube, also known as BA stainless steel tube or stainless steel clean tube, can achieve a relatively high level of surface smoothness.

Generally speaking, stainless steel bright annealed pipes have high smoothness and cleanliness on their inner and outer surfaces after bright annealing treatment. The inner surface smoothness of this type of pipeline is usually below 0.4 microns, and some data indicate that its roughness Ra can be less than or equal to 0.4 microns, and some can even achieve better values. This smooth surface ensures minimal friction during the flow of liquids or gases, effectively preventing the accumulation of residues and inhibiting bacterial growth, making it ideal for applications that require high hygiene standards.

In addition, stainless steel bright annealed tubes also have good dimensional accuracy and weldability. It has high dimensional accuracy and can meet various high-precision requirements. During the welding process, it can also maintain the cleanliness and smoothness of the inner and outer surfaces of the pipeline.

Overall, the surface smoothness of stainless steel bright annealed tubes can reach a very high level, which makes them widely applicable in clean workshop buildings, biopharmaceuticals, clean laboratories, high-purity gas transportation and other fields. Meanwhile, its high smoothness and cleanliness also ensure the stability and reliability of the pipeline during use.
