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").
