What Are the Features of Stainless Steel Valve Elbows?

The stainless steel elbow has the following characteristics: reliable and safe connection, convenient and fast construction, good hygienic and environmental protection performance, small flow pressure loss, strong system compatibility, both visible and concealed, free of maintenance, superior economic performance, wide application. It is suitable for the transportation of civil low-pressure fluids such as cold and hot water, direct drinking water, heating, air conditioning, firefighting, gas, etc., and can also be used for the transportation of low-pressure fluids in industries such as medicine, beverages, food, and chemicals.

Stainless steel elbows will not produce corrosion, pitting or wear. Stainless steel is still one of the strongest materials among construction metal materials. Since stainless steel has good corrosion resistance, it can permanently maintain the integrity of engineering design. Stainless steel stamping elbows containing chromium are also a combination of mechanical strength and high elongation, which is easy to process and manufacture parts, which can meet the needs of architects and structural designers. All metals react with oxygen in the atmosphere to form an oxide film on the surface. Unfortunately, the iron oxide formed on ordinary carbon steel inherits oxidation, thereby expanding corrosion and eventually forming pores. Paint or oxidation-resistant metals (such as zinc, nickel, and chromium) can be electroplated to ensure the surface of carbon steel, but it is well known that this protection is just a thin film.

In addition, stainless steel elbows are resistant to the corrosion of steel by weak corrosive media such as air, steam, water and chemical corrosive media such as acids, alkalis and salts. In practical applications, steels that are resistant to weakly corrosive media are often referred to as stainless steel stamped elbows, while steels that are resistant to chemical media corrosion are called acid-resistant steel. Due to the different chemical composition, the former may not be able to resist the corrosion of chemical media, the latter is generally stainless steel. Stainless steel elbows containing chromium are also a combination of mechanical strength and high elongation. They are easy to process and manufacture parts, which can meet the needs of architects and structural designers.

The corrosion resistance of stainless steel elbows depends on the alloying elements contained in the steel. "Chromium" is the basic element for obtaining the corrosion resistance of stainless steel stamping elbows. When the chromium content in the steel reaches about 1, in the corrosive medium, the interaction of chromium and oxygen forms a very thin oxide film on the steel surface (from Passivation film), to prevent further corrosion of the steel substrate. Elbow pipe fittings have different production processes and processes, which need to be produced and processed according to certain conditions. Some problems should be paid attention to when processing elbow pipe fittings with different properties. The elbow is upside down. When manufacturing a long radius alloy elbow, the specifications of the steel pipe should be selected first, the material of the steel pipe should be proposed, and the steel pipe of good quality should be selected for production.
