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.
