Flanges are more important parts of pipelines. Some more important pipelines put forward higher requirements on flange materials during construction, such as higher strength, high-temperature resistance, high-pressure resistance, low-temperature resistance, corrosion resistance, wear resistance, etc. Carbon steel flange<\/a> cannot fully meet the requirements of special physical and chemical properties, so stainless steel flanges<\/strong> appear.<\/p>\n\n\n\n

Stainless Steel Flange is a flange made of stainless steel, referred to as ss flanges. The main standards are Stainless Steel Flange is a flange made of stainless steel material, which can generally be called stainless steel pipe flange, or stainless steel plate flange. Abbreviated as ss flanges. The main standards are ASME\/ANSI B16.5<\/a> and ASME\/ANSI B16.47<\/a>, the pressure is from CLASS75 to CLASS2500, and the size is from 1\/2″-60″. Stainless steel flanges have stronger and better corrosion resistance and are often used in pipelines with higher requirements.<\/p>\n\n\n\n

Stainless Steel<\/h2>\n\n\n\n

Resistance to corrosion and staining, low maintenance, and familiar luster make stainless steel an ideal material for many applications where both the strength of steel and corrosion resistance are required. Moreover, stainless steel can be rolled into sheets, plates, bars, wire, and tubing. These can be used in cookware, cutlery, surgical instruments, major appliances, vehicles, construction material in large buildings, industrial equipment (e.g., in paper mills, chemical plants, water treatment), and storage tanks and tankers for chemicals and food products.<\/p>\n\n\n\n

The biological cleanability of stainless steel is superior to both aluminum and copper, having a biological cleanability comparable to glass. Its cleanability, strength, and corrosion resistance have prompted the use of stainless steel in pharmaceutical and food processing plants.<\/p>\n\n\n\n
