A complete,rewrite of the B2.2-1968 standard on Dryseal Pipe Threads has been completed, with the product,thread data in separate documents from the gaging standards for Dryseal Pipe Threads. The system of numbering,to include metric conversions, is as follows:,ANSI B1.20.3-1976 Dryseal Pipe Threads (Inch),ANSI B1.20.4-1976 Dryseal Pipe Threads (Metric Translation),ANSI B1.20.5-1978 Gaging for Dryseal Pipe Threads (Inch),In preparation, B1.2O.6M Gaging for Dryseal Pipe Threads (Metric Translation),A complete rewrite of the B2.1-1968 standard on Pipe Threads (Except Dryseal) was then undertaken.,The system of numbering, to include metric conversions, is as follows:,ANSIlASME B1.20.1 Pipe Threads, General Purpose (Inch),In preparation, B1.20.2MPipe Threads, General Purpose (Metric Translation),These standards, ANSI/ASME B1.20.1 and B1.20.2M, have product thread dimensions and gaging in the,same document.
