JIS B2220 Flanges

JIS B2220 Flanges are made according to the Japanese international standard JIS B2220. The flanges range from ½ inches through 48 inches with pressure capacities ranging from 5k to 63K. The same pressure capacities can be expressed as PN6 to PN64 or class 150 to class 2500. The Jis B2220 Blind Flange is used to close the pipelines either temporarily or permanently.

The high maintenance systems use the flanges with bolts for easy removal. The permanent connections are made with welding the flanges to the pipes at the end. There are different types of blind flanges available as well. The Stainless Steel 10K JIS B2220 Flanges are made as screwed, forged, threaded or plate types. Each type can come with different face categories such as the raised face, flat face and ring type joint. Each of these can also come in different functional types such as slip on flanges, blind flanges, socket weld flanges, welded neck flanges, lap joint flanges and so on. The Jis B2220 2k Flanges can be tested for quality with different test methods such as EN 10204/3.1B. The suppliers are required to provide with a  raw material certificate for the Jis B2220 16k Flange and other flanges of this standard. The production of the flanges can also involve forging, heat treatment and machining. These depend on the material used for the making of the flanges. There are stainless steel, carbon steel, duplex steel and alloy steel flanges available in this standard. The SS 16K JIS B2220 Flanges are used in power generation, oil and gas, water lines, construction, engineering and in general corrosive applications as well.
