there are strict requirements for the dimensional accuracy of the tubes. Different caliber requirements will vary, in general, if the pipe caliber is small, the wall thickness is thin, the tolerance range of the pipe is in ± 0.05mm. but the pipe caliber of the larger precision tube tolerance range is basically in ± 0.05mm - ± 0.15mm.
Precision stainless steel tubes have requirements for the thickness of the tube, which is usually referred to as the wall thickness. Many tubes in the field of decorative tubes are falsely marked and are not the actual thickness, but if you do precision stainless steel tubes, it must be the actual thickness, and there are strict requirements for wall thickness error. For example, the wall thickness of 1.52mm tube, do precision tube requirements to achieve the actual thickness of 1.50mm, then the error must be ± 0.02mm, can not do well into the actual thickness of 1.40mm. The actual situation is that even if the thickness has the error, the error range should be reduced as much as possible. Of course, the error of the thickness is directly related to the steel strip calendering.
