Flange For Wellhead
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.

Our drilling BOP includes an annular BOP and a ram BOP. The annular
BOP, consisting primarily of a shell, a header, a rubber core and a
piston, and which by design is equipped with a hydraulic control
system, can be used independently but usually operates in tandem
with a ram BOP.
In accordance with API 16A requirements, the connections at the top
and bottom of the rig are either flange or studded flange and can
be conveniently connected to a drilling spool or ram BOP.
Our ram BOP features an advanced design that is nonetheless easy to
operate.
The ram BOP is reliable, and spare parts can be easily replaced. As
with the annular BOP, it can be used independently or coupled to
other BOP combinations.
A hydraulic system can be used to open and close the ram, but
should there be no power or air on site to run this system, the
rams can be opened or closed manually.
