Small diameter thin-walled stainless steel seamless pipe is also called stainless steel capillary seamless pipe or thin-walled seamless pipe, and finish rolled pipe is also called cold-rolled precision steel pipe.
In the production process of thin-walled stainless steel pipe, it is necessary to maintain a stable wall thickness of 0.4 ~ 0.9mm
The outer diameter is 5mm-60mm and the wall thickness is 0.4mm-1.0mm.
The outer diameter tolerance is ± 0.05, and the wall thickness tolerance can also reach ± 0.05 mm, sometimes ± 0.03 mm,
The dimensional tolerance of inner hole is strictly controlled, which can reach ± 0.03, less than 0.02-0.05mm, and the internal and external surface finish RA ≤ 0.8 μ M after polishing, the internal and external surface finish of the pipe can reach RA ≤ 0.2-0.4 μ M (such as mirror)
If the customer requires the finish of the outer surface, it can even reach the surface below 0,1 or even 8K
Processing method of small diameter thin wall stainless steel seamless pipe:
Domestic cold-rolled thin-walled stainless steel tubes are basically formed by three high cold rolling of industrial tubes. Reducing the wall thickness from thick to thin, this process can make the wall thickness uniform and smooth, and reduce the wall tension.
The wall reduction process is not accompanied by bright annealing. Only after the cold rolling meets the dimensional requirements, the inner and outer walls can be bright annealed, so that no oxide layer will be formed, the inner and outer walls are bright and beautiful.
