Class 150 ASTM A182 F316/F316L Stainless Steel Pipe Flanges WN RF Weld Neck Raised Face
Stainless steel pipe flanges find application in various industries and sectors where piping systems are used. Some common applications of stainless steel pipe flanges include:
Petrochemical Industry: Stainless steel pipe flanges are extensively used in the petrochemical industry for connecting pipes, valves, and equipment in refineries, chemical plants, and offshore platforms. They are suitable for handling corrosive fluids and high-pressure environments.
Oil and Gas Industry: Stainless steel pipe flanges are widely employed in oil and gas exploration, production, and transportation. They are used in pipelines, wellheads, processing facilities, and storage tanks. Stainless steel's corrosion resistance makes it ideal for handling petroleum products and natural gas.

Materials: ASTM A182 F316/F316L
Stainless steel 316/ 316L flanges have enhanced resistance to pitting corrosion in chloride environments due to the addition of molybdenum. The letter “L” denotes low carbon content. According to ASME B16.5 and ASME B16.47, SS 316/ 316L flanges may be made from forgings of ASTM A182 Grade F316 or F316L, castings of ASTM A351 Grades CF8M or CF3M, and plates of ASTM A240 Grades 316 or 316L.
SS 316/ 316L flanges can be furnished in diverse types such as welding neck, slip on, blind, socket welding, lap joint, threaded, and reducing, etc. Flanges of ASME B16.5 may be provided in sizes 1/2″ through 24″ in Class 150, 300, 400, 600, 900, 1500, 2500. Flanges of ASME B16.47 Series A may be provided in sizes 26″through 60″in Class 150, 300, 400, 600, 900; while flanges of ASME B16.47 Series B may be provided in sizes 26″ through 60 in Class 75, 150, 300, 400, 600, 900

Flange Type:Weld Neck Flange (WN)
A weld neck flange, also called a tapered hub flange or high-hub flange, is a kind of flange that can relocate stress to the pipes, ensuring a decrease in high-stress concentration at the bottom of the flange. There are two welding neck flanges designs – the first type is used with pipes while the second, longer type cannot be used with pipes but with a process plant. The weld neck flange comprises of a round fitting that extends beyond the rim of the circumference. These flanges, typically manufactured from forging, are actually welded to pipes.
Face Type: Raised Face (RF)
The Raised Face flange is the most common type used in process plant applications, and is easily to identify. It is referred to as a raised face because the gasket surfaces are raised above the bolting circle face. This face type allows the use of a wide combination of gasket designs, including flat ring sheet types and metallic composites such as spiral wound and double jacketed types.
The purpose of a RF flange is to concentrate more pressure on a smaller gasket area and thereby increase the pressure containment capability of the joint. Diameter and height are in ASME B16.5 defined, by pressure class and diameter. Pressure rating of the flange determines the height of the raised face.
