ASME B16.5 Class 150 Weld Neck Flange

ASME B16.5 is a standard developed by the American Society of Mechanical Engineers for pipe flanges and flange connections. This standard provides detailed specifications for flanges of various sizes, pressure levels, materials, and surface types to meet the needs of various industrial applications. ASME B16.5 Class 150 weld neck flange, as an important type, is widely used in industries such as petroleum, chemical, natural gas, power, pharmaceuticals, and food.

Alloy steel class 150 weld neck flange have strong corrosion resistance, high temperature resistance, excellent sealing performance, and rigid and elastic requirements, and are widely used in various industrial fields.

ASTM A182 Stainless Steel Flange

ASTM A182 F304/304H/304L are all austenitic stainless steel materials, which are commonly used in the raw materials of ASTM A182 class 150 weld neck flange. Their prices are relatively cheaper than stainless steel materials such as 316 and 904, so they are widely used in pipeline systems.

Duplex Stainless Steel Class 150 Weld Neck Flange

ASTM A182 F51/53/55 is a duplex stainless steel that is commonly used for forging ASTM A182 class 150 weld neck flange. Duplex steel is more commonly used in pipelines used in some special environments, where higher material requirements are imposed, and it can play a greater role.

Notes

1) Dimension B corresponds to the pipe inside diameter. Values quoted assume 40S/Standard wall thickness.
2) Weights are based on manufacturer’s data and are approximate .
3) Flat face flanges may be provided at full thickness, C, or with raised face removed (the latter is nonstandard).
4) The blank space needs to be provided by purchaser.
5)  If you need class 300 ,600 ,900 ,1500 ,2500 flange dimensions & weight,please contact us.
