Stainless Steel Flanges

Stainless Steel Flange is an indispensable part for a stainless steel piping system, that connects the pipe to another pipe or pipe to a valve. There are holes in the flange, and get the assembly with bolts tightly. Stainless steel flanges are used in pairs or match with the flanged valves. In pipeline engineering, flanges are mainly used for pipe connection. It has different connected ends, such as butt-welding, socket-welding, threaded, etc. Different pressure flanges have different thicknesses and use different connection types. Types Of Industrial Flanges Hunan Great Steel Pipe supplies the type of industrial flanges you need for your project. Our flanges are manufactured in a wide range of materials and are engineered to meet all industry standards and service requirements.Most commonly used flanges are weld neck flange, slip-on flange, blind flange, socket weld flange, threaded flange, and lap joint flange (RTJ Flange):
Material Stainless Steel Grades Standard Grades: Stainless Steel, Sizes: 1/2” to 48” Stainless Steel 304/304L, 316/316L, 304H, 316H, 309, 310S, 317L, 321/321H, 347/347H, 904L, DUPLEX 2205 / SUPER DUPLEX 2507 Applications Stainless steel flanges are used as a connection component for pipes, valves, pumps, and other equipment from pipeline systems.
Slip-on flanges The flange is slipped over the pipe and then welded both inside and outside to provide sufficient strength and prevent leakage. Slip-on flanges are also used as loose back-up flanges when stub ends are used.
Blind flanges This is a flange without a centre bore, used to shut off a piping system or vessel opening.
Weld neck flanges This is a flange without a centre bore, used to shut off a piping system or vessel opening.
Lap joint flanges This is again similar to a slip-on flange, but has a radius at the intersection of the centre bore and the flange face to accommodate a lap stub end.
