API 6A DSA/DSAF Wellhead Flange Double Studded Adapter Flange
API 6A DSA/DSAF Wellhead Flange Double Studded Adapter Flange
Description of Double Studded Adapter Flange:
Double Studded Adapter Flange (DSAF) or Double Studded Adapter
(DSA) is a flange with a through bore and a ring groove on each
side, drilled and tapped bolt hole sets on both sides and tapped
end studs complete with nuts fitted on both sides. Unlike a spacer,
the two sides are usually different in size and/or pressure rating.
Double studded adapter flanges are commonly utilised to connect and
adapt flanges with different nominal sizes, pressure ratings, and
configurations.
All of our double studded adapter flanges(DSAF) are fully designed,
manufactured, and tested according to API 6A and NACE MR0175
standards. The standard material is high quality integral forged
AISI4130 alloy. Available in sizes from 1-13/16" to 30" and working
pressure up to 15000PSI. For sour service, all ring grooves can be
inlaid with stainless steel SS316 or inconel 625 for better
protection. The studs and nuts are available with Zinc Coated,
Cadmium Coated, or Xylan Coated. Other sizes, material, and
pressure ratings are also available upon request. Aside from API6A
double studded adapter flanges(DSAF), we also produce and supply
other types API 6A flanges, such as threaded flanges, spacer spool
flanges, blind flanges, companion flanges, target flanges, test
flanges, and adapter spools for all client needs.
