Stainless Steel Flanges

A flange can be generally classified as a plate, forging or cast ring that is used to join sections of tube, pipe or items of plant such as a pump or valve. There are a number of different standards applicable to flanges commonly used in industry today. The three which are most frequently requested are, BS 4504, ANSI B 16.5 and BS10 (Tables D and E).
