ASME B16.5 Class 150 Flanges | Welding Neck
The ASME B16.5 Class 150 Weld Neck Flange is a fixed-parameter Weld neck flange that can withstand a pressure of 150 pound force per square inch (PSIG) in the ANSI (American National Standards Institute) standard. YANHAO ASME B16.5 Class 150 Cast flanges are made of Stainless Steel, Carbon Steel, and Alloy Steel, and can be sealed with gaskets or O-rings.
We usually provide standard bottle flanges; if you need to order flanges of special types and hole diameters, please get in touch with our experts.

Weld Neck Flange
Weld Neck Flange is a type of industrial pipe connection, especially used in pressure pipeline systems. Thanks to the high structural strength, sealing performance, corrosion resistance, and the characteristics of withstanding high temperature and pressure of the welding neck flange, it can be used for oil transportation pipelines, ship pipeline systems, and the transportation of raw materials in chemical plants, etc.
