Stainless steel flanges are widely used in large-scale pipeline construction because of their excellent characteristics. Due to stainless steel flange is not a common spare parts, so peoples not quite well know the stainless steel flange and what are they advantage?
Stainless steel flange also called flange or Flange disc which use to pipe or valve end connected parts. Stainless steel flange is connected with pipe end on both sides and the flange itself has holes. Through these holes to tightened both end of flanges that can connect the pipe and prevent leakage. Stainless steel flange is widely used in Petroleum, Chemical, Food Industries, Construction,Ship building, Medicine and other industries. The stainless steel flange is so popular widely used, it is because of the material used in stainless steel flange like 304,316,321,310S,347H etc. Stainless steel itself has very excellent performance, which in use can effectively resist corrosion, Pitting, Rust and stainless steel is very rigid, difficult to wear. Stainless steel is one of the strongest metal materials used in construction.
Stainless steel has excellent corrosion resistance,thus permanently preserving the engineering integrity of structural components. Different stainless steel material grade has different properties. For example,Chromium stainless steel flanges have high mechanical strength and high tensile properties, making it easier for parts to be forged to meet the needs of architects and structural designers.
All the metals react with oxygen in the atmosphere and form an oxide film on the surface. However, this oxide film has different manifestations in different metals. For example, the oxide film structure on the surface of ordinary Carbon steel pipe fittings is very loose. There is a large distance between from rust, and there is no way to prevent the further erosion of water and Air. So the oxidation situation will continue to expand. Stainless steel pipe fittings and carbon steel pipe fittings on the contrary, the surface of stainless steel pipe fittings can form a dense oxidation film which can block the progress of water and air oxidation.That why stainless steel has excellent performance of oxidation resistance and corrosion resistance.
Matters needing attention when stainless steel flange welding:
In order to ensure rapid cooling of the stainless steel flange, the welding current should not be too large, so that the operation can avoid damage to the stainless steel flange.
Producing stainless steel flange add appropriate stability elements are more commonly used in process, such elements can make the stainless steel flanges performance much better in a way.
