Blind pipe flanges are typically provided with a raised face, flat face, or RTJ facing. When a raised face is necessary for blind pipe flanges, the standard height is 1/16" for blind pipe flanges under 400#. For blind pipe flanges of 400# and up, the standard blind pipe flange raised face height is 1/4".
Steber Steel manufactures blind pipe flanges in all steel material grades, including carbon blind pipe flanges, stainless steel blind pipe flanges and alloy blind pipe flanges. Steber Steel also has many different blind pipe flanges in stock and ready to ship. Blind pipe flanges in stock include ANSI B16.5 blind pipe flanges, ASME B16.47 Series "A" blind pipe flanges, ASME B16.47 Series "B" blind pipe flanges and Pressure Vessel weld neck pipe flanges. Steber Steel also manufactures custom weld neck pipe flanges per customer requirements.
