GB/T 9117.1-2000Hubbed socket welding steel pipe flanges (English PDF)

Foreword

GB/T 9112 ~ 9124-2010 "steel pipe flanges" series Standard is a modified ASMEB16.5-2009 "pipe flanges and flanged pipe Member (NPS1/2 ~ 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 data Class400 nominal pressure of the flange, this standard does not incorporate Class400 Flange data;

--- ASMEB16.5-2009 standard includes flange nominal size of the data NPS31/2, this standard does not NPS31/2 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;

--- EN1092-1:2007 standard does not include ring joint face flange, according to our user's requirements, the standard adds the PN Ring joint face flange marks;

--- EN1092-1:2007 standard with no neck socket welding steel pipe flanges, the present standard according to the actual needs of domestic users, an increase of PN series energetic socket welding steel pipe flanges.

This standard replaces GB/T 9117.1-2000 "projecting face with neck socket welding steel pipe flanges", GB/T 9117.2-2000 "Hubbed Socket welding steel pipe flanges ", GB/T 9117.3-2000" tongue and groove with neck socket welding steel pipe flanges "and GB/T 9117.4-2000" ring Connecting surface with neck socket welding steel pipe flanges ", compared with the original standard main changes are as follows.

--- The original four with neck socket welding steel pipe flanges standards into one standard;

--- According to the actual needs of domestic users, increasing the nominal pressure range PN series with neck socket welding steel pipe flanges, for PN10 ~ PN160, nominal size range of DN10 ~ DN50;

--- According ASMEB16.5-2009 standards for Class flange dimensions data were comprehensive revision;

--- Increasing the variety of sealing surface of the scope of application form;

--- Marked revised;

--- According ASMEB16.5-2009, belonging to the original standard flange nominal inter-American system mark in the following table has been modified.

PN20 to Class150, PN50 to Class300, PN110 to Class600, PN150 to Class900, PN260 to Class1500.

The standard proposed by China Machinery Industry Federation.

This standard by the National Standardization Technical Committee pipe accessories.

This standard was drafted. the machine Productivity Promotion Center, Zhejiang Chaoda Valve Co., Ltd., Jiangsu Haida Pipe Fittings Co., Ltd., Hebei San Bao silver-day Group of high-pressure pipe flanges Limited, Paul Group Co., Ltd..

1 Scope

This standard specifies the nominal pressure and marked with a PN with Class labeled with neck socket welding steel pipe flange type, size, technology to be Sum mark.

This standard applies to nominal pressure PN10 ~ PN100 and Class150 ~ Class1500 with neck socket welding steel pipe flanges.
