ASTM A182, ASTM A240 Stainless Steel 316/316L Weld Neck Flanges Manufacturers

Metline is a professional manufacturer and exporter of stainless steel 316/316L weld neck flanges with precision machining facilities. We produce stainless steel 316/316L weld neck flanges as per ANSI B16.5, DIN Standard and EN1092-1 in size range of 1/2” to 60” NPS. Weld neck pipe flanges are connected to the pipe by welding the pipe to the neck of the pipe flange, which helps to pass on the stress from the weld neck to the pipe itself. This also reduces high stress concentration at the base of the hub of the weld neck pipe flanges. Weld neck pipe flanges are generally used in high pressure applications, where hot or cold temperatures exist. The inside diameter of a weld neck pipe flange is machined to match the inside diameter of the pipe. We produce flanges in carbon steel, stainless steel, high nickel alloys, duplex/super duplex, copper nickel, titanium and special alloys.

About 316/316L Stainless Steel

316 grade stainless steel is an austenitic form of stainless steel known for its 2-3% molybdenum content. The added molybdenum makes the metal more resistant to pitting and corrosion, as well as improving resistance when exposed to elevated temperatures. Grade 316 is the standard molybdenum-bearing grade, second in overall volume production to 304 amongst the austenitic stainless steels. The molybdenum gives 316 better overall corrosion resistant properties than Grade 304, particularly higher resistance to pitting and crevice corrosion in chloride environments. 316L is low carbon with 0.03% maximum to prevent the loss of corrosion resistance caused by chromium carbide formation during welding. 316 is 0.08% carbon maximum. Neither grade has a specified minimum carbon content. The strength requirements for 316 are a little higher than for 316L.

A flange is a method of connecting pipes, valves, pumps and other equipment to form a piping system. It also provides easy access for cleaning, inspection or modification. Flanges are usually welded or screwed. Flange joints are made by bolting together two flanges with a gasket between them to provide a seal. Flanges are commonly used to connect valves into pipework making it easier for removal and maintenance. There are many common flange standards and flanges within the same standard can either be flat (commonly cast iron, ductile iron) or raised face (commonly cast steel and stainless steel).
