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".
Steber Steel 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. Steber Steel 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.
