A flange is designed to connect sections of pipe or tube, or to join the pipe or tube to an assembly such as a pressure vessel, valve or pump. Flanges are joined by bolting, and sealing is completed with the use of gaskets and other sealing methods, and fixed to the piping system by welding or threading.


A comprehensive range of Table D and E flanges to AS 2129, and forged flanges to ASME standards in ratings of class, are stocked by Prochem throughout Australia in sizes DN 15 (NPS 1/2″) though to DN 400 (NPS 16″)


Larger sizes to DN 1500 (NPS 60″) and ratings to Class 2500 are also available through our worldwide network of quality approved mills and stockists.
