Slip On Flange

What is a Slip-On Flange?

Slip on flange (SO flange),as the name implies, is the flanges slipping on the pipes or fittings when connection. The pipe shall be inserted into the flange inner bore at a bit distance from the flange surface to ensure that the sealing of both flanges will not be affected.

The inner bore of slip on flange is slightly bigger than the pipe’s outside diameter, to make sure the pipe or fitting end can slip into the SO flange. Commonly, the slip on flange can be fillet welded with the pipe on the two sides.
