Product Information

Stainless steel pipe flanges are components used in piping systems to connect pipes, valves, pumps, and other equipment. They provide a means for easy assembly, disassembly, and maintenance of the system.

Materials: ASTM A182 F316/F316L

Stainless steel pipe flanges are typically made from austenitic stainless steel grades such as 304/304L, 316/316L, 317/317L, 321/321H, and others. These stainless steel grades offer excellent corrosion resistance, durability, and strength.

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.

Flange Type: SO-Slip On Flange

Slip on flange also simplified as SO flange. SO flanges slip over pipes and are designed to bit slightly bigger on the inside than the pipe. They connect to the pipe through a fillet weld at the flange top and bottom. It is used to insert the pipe into the inner hole of flange, as the flange inner diameter is little bigger than the pipe’s outer diameter, pipe and flange could be connected by lap welding at the top and bottom of the flange.

Face Type: RF- Raised Face

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.
