GB Flanges ASME B16.5 GB slip on Flanges Supplier, GB weld neck Flange, GB Socket Weld Flanges, GB Threaded Flanges, GB Plate Flange, GB Spectacle blind Flanges Manufacturer in India. The GB flange system, also known as the Chinese standard flange system, is a set of specifications for manufacturing flanges in China. It is created to be consistent with both the ANSI flange system and the DIN flange system, which are widely used in the United States and Europe, respectively. The GB flange system includes a range of flange types and sizes, such as welding neck flanges, slip-on flanges, blind flanges, and threaded flanges, with dimensions specified in millimeters. GB flanges are commonly used in various industries in China, such as oil and gas, chemical, and construction industries. GB/T 9112-9113.4-2000 specifies the dimensions and technical requirements for welding neck flanges and slip-on flanges in nominal sizes ranging from DN10 to DN2000 and DN10 to DN1800, respectively. GB/T 17241.1-17241.7 specifies the dimensions, tolerances, and technical requirements for various types of steel pipe flanges, including welding neck flanges, slip-on flanges, threaded flanges, and blind flanges, in nominal sizes ranging from DN10 to DN4000. GB/T 15530.1-15530.8 specifies the dimensions, tolerances, and technical requirements for socket welding flanges, threaded flanges, blind flanges, and slip-on flanges in nominal sizes ranging from DN10 to DN2000 and pressure ratings from PN0.6 to PN6.4 MPA. The pressure ratings for GB flanges range from PN0.6 to PN6.4 MPA, which corresponds to pressure classes from 150 to 600 in the ANSI flange system and from PN2.5 to PN100 in the DIN flange system.SpecificationsDimensionsApplications  Suppliers of GB Welding Neck Flange, Check Sizes And Dimensions Of ANSI B16.5 GB Forged Flanges, Ready Stock of GB Socket Weld Flange, GB Ring Type Joint Orifice Flange, GB Blind Flanges.
