Introduction to standards:

JB/T 10000-1999 This standard is a revision of ZB J41 017-89 "55° tapered pipe thread rolling wheel". During the revision, only editorial changes were made according to relevant regulations, and the technical content was not changed. This standard specifies the type and size, tooth size and deviation, technical requirements, and basic requirements for marking and packaging of 55° cylindrical pipe thread rolling wheels (hereinafter referred to as thread rolling wheels). This standard is applicable to R series thread rolling wheels for processing pipe threads sealed with threads (according to GB/T 7306-1987 "Pipe threads sealed with threads"). The thread rolling wheels are divided into 45 types, 54 types, and 75 types according to the shaft diameter of the thread rolling machine. This standard was first issued on .
