Introduction to standards:

JB/T 2302-1999 This standard is a revision of JB 2302-78 "Double-barrel mesh filter types, parameters and dimensions". During the revision, the flange connection dimensions were modified according to JB/T 79.1-94 "Raised integral cast steel pipe flange". This standard specifies the types, parameters and dimensions of double-barrel mesh filters. This standard is applicable to double-barrel mesh filters that filter lubricating oil in the thin oil lubrication system of heavy-duty and mining equipment. This standard was first issued on October 1, 1978. JB/T 2302-1999 Double-barrel mesh filter types, parameters and dimensions JB/T2302-1999 standard download decompression password: www.bzxz.net
