A flange is a ring of steel (forged, cut from plate, or rolled) designed to connect sections of pipe, or to join pipe to a pressure vessel, valve, pump or other integral flanged assembly. Flanges are joined to each other by bolts, and to the piping system by welding or threading (or loose when stub ends are used). Stainless steel flange simplified as SS flange, it refers to the flanges that made of stainless steel. Common material standards and Grades are ASTM A182 Grade F304/L and F316/L, with pressure ratings from Class 150, 300, 600 etc and to 2500.

Carbon steel is a special type of steel that, as the name suggests, has a higher carbon content than other types of steel. Most types of steel have relatively low carbon content, around 0.05% to 0.3%. In comparison, carbon steel has a carbon content of up to 2.5%. Twenty and a half percent carbon may sound insignificant, but it brings several attractive benefits not found elsewhere.

310S stainless steel has good high temperature resistance. When the temperature exceeds 800 [1], it begins to soften, and the allowable stress begins to decrease continuously. The maximum operating temperature is 1200 ¡ãC. Due to the high content of nickel (Ni) and chromium (Cr), it has good oxidation resistance, corrosion resistance, acid and alkali resistance, and high temperature resistance. After the content, the strength is improved due to its solid solution strengthening effect. The chemical composition characteristics of austenitic stainless steel are based on chromium and nickel with elements such as molybdenum, tungsten, niobium and titanium added. Therefore, it has high strength and creep strength at high temperature.

Very little carburization was observed in this alloy before exposure for at least 1000 hours.

The flanges are used in high temperature services to connect pipes and piping materials together.

It accounts for around 80% of overall duplex stainless steel production.

Welded A234 WPB pipe fittings mean the large sizes fittings which are pieces welded from steel plates.

The standards set for ASTM A694 is more rigorous than the two above. Its requirements for high-pressure fluid transmission of oil and gas piping is stringent. Because of the stringent conditions with the steel grade, manufacturers have to develop an even stronger steel for both low temperatures and high temperatures.

The applications of the flanges include petroleum, petrochemical, oil and gas and other high performing piping systems.

Like steel, 316 stainless steel is primarily composed of iron and carbon. However, stainless steel also contains at least 10.5% chromium, a metallic element that imparts a metal surface finish and excellent corrosion resistance. Stainless steel is ideal for long-term applications that will be exposed to elements, moisture and potentially corrosive chemicals. It is also ideal for sensitive industries such as food preparation and pharmaceuticals, as the risk of contamination is much lower.
