API N80-1 Seamless Casing Pipe with BTC threads
N80 Seamless Casing Pipe includes N80-1 and N80-Q steel grades. These 2 grades are the same in both of chemical composition and mechanical properties. The only difference is the Heat Treatment. The latter one N80-Q steel pipe requires heat treatment before they are to be manufactured into casing pipes.
