mandated that the IBR Flange is to be inspected by a company that has been approved by the Central Boiler Board or CBB. The CBB has to certify all pressure equipment, including components such as flanges using steam. Only those components for e.g. IBR Approved Flanges that have been approved could be imported into India. Industries such as fossil and nuclear energy require good quality certified components to be used for their applications. The materials used for producing these flanges according to IBR Pipe Flange include different grades of stainless steel, alloy steel as well as carbon steel.
