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.
