In addition, other professional such as industrial furnace, thermal engineering, water supply and drainage, heating and ventilation, automatic control, etc., also often use SO flange There are two main international pipe flange standards, namely the European pipe flange system represented by German DIN(including the former Soviet Union) and the American pipe flange system represented by American ANSI pipe flange.
