Scope

JB/T 2001.7-1999 is the English-translated version of 水系统方附接法兰型式与尺寸(PN=31.5MPa).

Part 7 of the JB/T 2001 series, JB/T 2001.7-1999 is a recommended standard of the Chinese machinery industry covering square attachment flanges for high-pressure water systems. It gives the types and the dimensions of these flanges for systems working at a nominal pressure of 31.5 MPa. The same series carries matching flange parts for lower pressures, so the sizes settled here belong to the 31.5 MPa range alone. The part is used with JB/T 2001.5-1999 and is classified under J20 and ICS 23.100. It supersedes JB 2007-1984. It was issued on 1 January 1999.
