ASME B16.5 Weld Neck Flange

Weld Neck Flange Series A Manufacturer, PN16 Rasied Face Weld Neck Flange Series B, ASME B16.5 Weld Neck Flange Dimensions

Weld Neck Flange SuppliersWe as Metalfed Engineering are a prominent manufacturer and stockist of Weld Neck Flanges, which offer good strength and toughness at cryogenic temperatures. Series A Weld Neck Flange is non-magnetic and will not be affected by additional heat treatment. ASME B16.5 Weld Neck Flanges is a standard specification for chromium and chromium-nickel steel used for pressure vessels and for general applications. Weld Neck Flange Series B offers excellent corrosion resistance and mechanical properties.
Series A and Series B Weld Neck Flange represents an excellent combination of corrosion resistance and manufacturability. BS4504 Weld Neck Flange is widely used in the construction of nuclear reprocessing plants. It is an alloy of nickel and copper, together in the company of having fortification elements like iron and manganese. Much higher forging pressures are required than for plain and low-alloy steels. General-purpose steel, Carbon Steel Weld Neck Flanges was developed to offer increased corrosion resistance. RTJ Weld Neck Flange is used for welding applications due to its lower carbon content. If carbide precipitates are a problem, Class 300 Weld Neck Flanges may be a better option because of their inferior content of carbon material. It is used to shape wire, washers, shape springs, spring clip, retainers, shield, cable, etc.ASME B16.5 Weld Neck Flange Suppliers, Weld Neck Series A / Series B Flange
