اکنون پرس و جوDec 31 32 Pipe Mill Tolerance in accordance with ASTM ASME BM is considered to be 177 125 of the nominal pipe wall thickness tn That is to say if you have a pipe supplied with a nominal thickness tn and you need to measure the actual thickness you can find that there is a deviation reaches about 177 125 tnPipe and tube undertolrances are almost 125 of the nominal wall thickness but sometimes there are differences for different materials so for any specific material it shall be referred to the suggested pipe or tube material specification to obtain the exact amount of mill undertolranc

اکنون پرس و جوThe term Mill Tolerances is used to describe permissible deviations from the published dimensions of cross sectional profiles listed in mill catalogs and from the thickness or lengths specified by the purchaser Some of the variations are negligible in smaller shapes but tend to increase and must be taken into consideration in detailing and hi in pipes and fittings thickness calculation as per ASME B313 for semless pipes we go for mill tolerance of 125 in general what is the value if it is welded pipe from where i can take that tolerance value it is in or in mm or inch will it varies from material to material kindly help me out
