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 EN1092-1.2007 standard main difference is as follows. --- The preparation of this standard format ASMEB16.5-2009 and EN1092-1.2007 different standards; --- EN1092-1.2007 standard does not include two DN175 and DN225 nominal size, according to users of marine flange Requirements, this standard PN flange marked increase of DN175 and DN225 only two male marine said flange size. This standard replaces GB/T 9121.1-2000 "with weld ring projecting Loose plate steel pipe flanges", GB/T 9121.2-2000 "uneven surface Loose plate flat welding steel pipe flanges ", GB/T 9121.3-2000" tongue and groove weld flat Loose plate steel pipe flanges "and GB/T 2508-1989 "Marine lap welding steel ring set loose steel flanges (four into bits)", compared with the original standard main changes are as follows. --- The original three flat welding Loose plate steel pipe flanges with GB/T 2508-1989 integrated as a standard; --- According to EN1092-1.2007 standard, increasing the O-ring sealing surface type; --- According to EN1092-1.2007 standard, flange dimensions data were comprehensive revision; --- Increased DN175 and DN225 only two male Marine flange nominal size; --- Various sealing surface increases the scope of application form. 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., China Shipbuilding Technology and Economy Research Institute, Jiangsu Haida Pipe Fittings Co., Ltd.
