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

ICS21.010 Machinery Industry Standard of the People's Republic of China JB/T2302—1999 Double cylinder mesh filter Type, parameters and dimensions of double cylinder mesh filter Published on 1999-06-28 National Machinery Industry Bureau Implemented on 2000-01-01 JB/T2302—1999 This standard is a revision of JB2302-78 "Double cylinder mesh filter type, parameters and dimensions". Compared with JB2302-78, the main technical content of this standard has changed as follows: the flange connection size was originally based on JB76-59, but now it is based on JB/T79.1-94. This standard replaces JB2302-78 from the date of implementation. This standard is proposed and managed by the Metallurgical Equipment Standardization Technical Committee. The drafting unit of this standard: Xi'an Heavy Machinery Research Institute. The main drafter of this standard: Qi Dingshun. This standard was first issued in October 1978. 1 Scope Machinery Industry Standards of the People's Republic of China Double cylinder mesh filter Type, parameters and dimensions Typeparameters and dimensions of doublecylindericneting-filter This standard specifies the type, parameters and dimensions of double cylinder mesh filter.
