Stainless Steel Flange Fittings

Stainless Steel Flange Supplier / Stainless Steel Flange Exporter / Stainless Steel Flange Manufacturer in China.

One of the key factors to keep in mind when purchasing pipe flanges is the material choice. These materials include stainless steel, nickel alloys, and plastics. Stainless steel is the most common material for oil rigs and piping systems.

  • Stainless steel flange is highly resistant to corrosion compared to other metals.
  • Stainless steel flange can withstand high pressure and temperatures depending on the metal grade used. ASTM A182 flanges can handle extreme temperatures of about 500 to 800 degrees Celsius.
  • Stainless steel flange is highly durable. Your pipe flanges can last for decades, supporting liquid and gas flow within your piping system.
  • Based on these factors, stainless steel is an ideal choice for pipe flanges and fittings.

Plate flanges are most used in fuel and water pipelines, where two flange plates are bolted together with a gasket in between them. 

Estan pipe fittings Blind Flange RF.500x500 image

Blind Flanges are manufactured without a bore and used to blank off the ends of piping, valves, and pressure vessel openings.

Socket Weld Raised Face Flange

Socket weld flange simplified as SW flange, it has a recessed area (like a shoulder) in the flange bore.

Estan pipe fittings Lap Joint Flange.500x500 image

Lap Joint Flange does not have a raised face, they are used in conjunction with a “Lap Joint Stub End”.

Estan pipe fittings weld neck flange image

A weld neck flange is a type of industrial flange designed to transfer stresses to the pipe to reduce high-stress concentrations.

Estan pipe fittings Threaded Flange ASME B16.5.500x500 image

Threaded flanges can be connected to pipes without welding. It can be equipped with a tapered thread (screw) in the flange hole.

Estan pipe fittings Orifice Flange ASME B16.36 image

An Orifice Flange is used in combination with orifice meters to measure the flow rate of oil, gas, and other liquids.
