Slip on flanges,like plate flat welding flanges, are flanges that extend steel pipes, pipe fittings,etc.into the flange and are connected to equipment or pipelines through fillet welds.They are also flat welding flanges because they have a short neck. Thereby increasing the strength of the flange and improving the bearing strength of the flange. So it can be used in higher pressure pipelines.
Available size:1/2’’-64’’

4.Plate flange
