SLIP ON FLANGE is also called SO flange, it is suitable for the connection of carbon steel pipes with a nominal pressure of no more than 2.5MPa. Slip on flange mostly used for when the medium conditions are relatively mild, such as low-pressure non-purified compressed air and low-pressure circulating water. Slip on flange place two fillets by welding, sliding inside the tube. So its installation cost is lower, requiring less precision in cutting the pipe.
