Pate flanges are secured to the pipe with a fillet weld at the bottom and the top of flanges with the pipes.The welding method is fillet weld,so the plate flange is not suitable for a high pressure application.

We mainly produce plate(flat) flange according to standards:ANSI/ASME B16.5,EN1092-1,BS4504,DIN,UNI,BS 10,GOST/ГОСТ 12820-80,etc.
