Foreword
GB/T 9112 ~ 9124-2010 "steel pipe flanges" series Standard is a modified ASMEB16.5-2009 "pipe flanges and flanged pipe
Member (NPS⅟ ~ NPS24) "and EN1092-1.2007" Flanges and their connecting pipes, valves, fittings and accessories, circular flange,
PN identification - Part 1. Steel flanges. " ASMEB16.5-2009 is a complete standards for Class marks flange,
EN1092-1.2007 is a complete standard PN mark on the flange. This series of standards using a combination of the above two criteria, including
Mark the relevant technical content Class flange and flange PN mark. This series of standards for a total 13 standard, this standard is one of a
standard.
This standard ASMEB16.5-2009 and EN1092-1.2007 standard main difference is as follows.
--- The preparation of this standard format ASMEB16.5-2009 and EN1092-1.2007 different standards;
--- ASMEB16.5-2009 standard includes a flange nominal pressure Class400 data, not included in this standard
Class400 flange data;
--- ASMEB16.5-2009 standard includes flange nominal size of the data NPS3⅟, this standard does not NPS3⅟ law
LAN data;
--- ASMEB16.5-2009 standard with inch bolt, bolt aperture is also used in inch sizes, this standard to metric bolts,
Aperture pattern also uses metric dimensions;
--- According to our user's requirements, this series marked flange standard PN nominal size range in EN1092-1.2007 standard
Registration done on the basis of appropriate expansion, including the addition of PN160 nominal pressure range of DN20 and DN32 two public
Nominal size;
--- EN1092-1.2007 standard does not include ring joint face flange, according to our users' requirements, this series of standards increased
Ring joint face flange PN tag.
This standard replaces GB/T 9123.1-2000 "flat, raised face steel pipe flanges cover", GB/T 9123.2-2000 "uneven surface steel pipe
Flange cover ", GB/T 9123.3-2000" steel pipe flanges with tongue and groove face cover "and GB/T 9123.4-2000" steel pipe flange ring joint face
Cover ", compared with the original standard main changes are as follows.
--- The original four steel pipe flange covers standards into one standard;
--- According to EN1092-1.2007 standard, PN flange cover marked increase in the O-ring sealing surface type;
--- According to user requirements, PN series flanges increasing the ring joint face (RJ);
--- According to EN1092-1.2007 standard, PN-labeled flange covers a comprehensive data size changes;
--- Increasing the variety of sealing surface of the scope of application form;
--- Marked revised;
--- According ASMEB16.5-2009, belonging to the original standard inter-American system has been modified flange nominal mark, PN20
To Class150, PN50 to Class300, PN110 to Class600, PN150 to Class900, PN260
To Class1500, PN420 to Class2500.
The standard proposed by China Machinery Industry Federation.
This standard by the National Standardization Technical Committee pipe accessories.
