Stainless steel tube tolerance chart
TAGS
If you plan to import stainless steel pipe, the tolerance comparison table of stainless steel pipe must be collected. We have compiled a tolerance comparison table, hoping to be helpful to your work.
1. Stainless steel pipe executive standard
GB / T 14976-2002 seamless stainless steel pipe for fluid transportation
GB 13296-2007 stainless steel seamless steel tubes for boilers and heat exchangers
2. OD tolerance & pipe thickness tolerance as per ASME
