API6A flanges are designed to join pipes together, increase support strength, or block off a pipeline. Type 6BX flanges are designed with a raised face thus preventing damage to the flange and gasket. API6A flanges are either bolted or studded and they are normally made of AISI 4130 forged alloy steel. The flange size ranges from 1-13/16'' to 26-3/4'' and pressure up to 20000psi. For sour service, all ring grooves can be inlaid with stainless steel SS316 or Inconel 625 upon request.
