Flanges are joined by bolting, and sealing is completed with the use of gaskets, and fixed to the piping system by welding or threading. A comprehensive range of Table D and E flanges to AS2129, and forged flanges to ANSI/ASME standards in ratings of class, are stocked by Prochem throughout Australia in sizes 15NB ( 1 /2 ") through to 400NB (16").
Larger sizes to 1500NB (60") and ratings to class 2500 are also available through our worldwide network of quality approved mills and stockists. Standard stocks include 304L and 316L stainless steels, with many other materials available on request including Cr Mo, low temperature alloys, nickel based alloys and duplex.
All flanges can be supplied complete with material certificates in strict accordance with applicable standards, under the control of Prochem’s ISO 9001 Quality Assurance Program.
