Blind Flange
Blind Flange
The Blind Flange is used at the end and to close the Pipeline systems and pressure vessel openings. It is commonly used in petrochemical, Pipeline engineering and water services. It is sometimes customized or machined to suitable for threaded reduction or welded reduction. Blind flange is typically provided with a raised face(RF), flat face(FF), or ring type joint face(RTJ). When a raised face is necessary for blind flange, the standard height is 1/16" for blind flanges under 400#. For blind flange of 400# and up, the standard blind flange raised face height is 1/4".
