Slip on weld flange is probably the most widely used flanges and is ideal for connection of steel pipes with nominal pressure less than 2.5MPa. There are several mounting holes around the perimeter and two flanges are bolted together with a gasket in between them. As the inside diameter of the slip on weld flange is determined by the outside diameter of the pipe, customers do not have to specify the pipe schedule when ordering it.
