Slip on Flange is essentially a ring that is placed over the pipe end, with the flange face extending from the end of the pipe by enough distance to apply a weld bead on the inside diameter.
Slip-on flanges (SOF) are designed to slip over the outside of pipe, long-tangent elbows, reducers, and swages. The flange has poor resistance to shock and vibration. It is easier to align than a weld neck flange. This flange is ideal for low pressure applications since the strength when under internal pressure is about one third that of a weld neck flange. This flange has a raised face.
As made obvious by their name, these pipe flanges slip over the pipe. They're manufactured with an inside diameter that is slightly bigger than the pipe's outside diameter. These attachments are connected to the pipe via fillet weld at the top and bottom of the flange.
Slip on pipe flanges are typically provided with a raised or flat face. When a raised face is necessary for slip on pipe flanges, the standard height is 1/16" for slip on pipe flanges under 400#. For slip on pipe flanges of 400# and up, the standard slip on pipe flange raised face height is 1/4".
Coastal Flange manufactures slip on pipe flanges in all steel material grades, including carbon slip on pipe flanges, stainless steel slip on pipe flanges and alloy slip on pipe flanges. Coastal Flange also has many different slip on pipe flanges in stock and ready to ship. Slip on pipe flanges in stock include AWWA slip on pipe flanges, ANSI slip on pipe flanges, Pressure Vessel slip on pipe flanges and slip on pipe flanges that match the OD and drilling of ASME flanges.
