API 6A 6BX Weld Neck RTJ Flange | 10000 PSI API Flange
C&N is a professional manufacturer of API 6A 6BX Welding Neck RTJ Flange in China,
What Is API 6A Type 6BX Weld Neck RTJ Flange?
The API 6A Type 6BX Weld Neck RTJ Flange is a high-pressure flange designed for wellhead and Christmas tree equipment in oil and gas production systems. These flanges are manufactured according to API 6A standards and are widely used in drilling, production, and high-pressure pipeline applications.
API 6BX flanges feature a raised face ring type joint (RTJ) sealing surface that provides reliable metal-to-metal sealing in extreme pressure environments. Compared with Type 6B flanges, the 6BX flange design prevents damage to the ring gasket and flange surface during make-up.
API 6A 6BX weld neck flanges are commonly rated for 10000 PSI (69 MPa) and can also be supplied for higher pressure classes up to 20000 PSI.
API 6A Type 6B and Type 6BX Weld neck flanges are normally made from forged alloy steel AISI 4130. API 6A flanges are designed to join pipes together, increase support strength, or block off a pipeline. Type 6B flanges are of the ring joint type and are not designed for face-to-face make-up. The connection make-up bolting force reacts on the metallic ring gasket. Type 6BX flanges are designed with a raised face thus preventing damage to the flange and gasket.
API 6A flanges are either bolted or studded and they are normally made of AISI4130 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.
Aside from API 6A welding neck flange, we also supply threaded flanges, blind flanges, companion flanges, target flanges, test flanges, double studded adapter flanges(DSAF), and adapter spools for all client needs.
