13 5/8" -5k x 13 5/8" - 5k Double Studded Adapter

Wellhead equipment

The DSA as per API 6A Standard is the part of wellhead sections, which is combination of flanges in different sizes and pressure ratings.

DSA Flange is a type of adapter. It can join two connections which differ from size or pressure rating by tapping stud hole intersection and drilling hole depth necessitate additional thickness.

Features:
DSAF in various sizes and pressure ratings.
DSAF's are a combination of flanges of different sizes and pressure ratings
DSAF is normally supplied along with appropriate size of studs with nuts duly fitted.
Adapter Flanges are used for transition in nominal size and/or pressure rating and where there is a restriction of space in the drill string.
They provide an ideal solution by hooking up two different equipment of different size and pressure rating.
DSAF's are available as per customer specified thicknesses, consistent with design considerations.
Basic material of construction is alloy steel. For corrosion resistance, overlays like SS 316L or can be incorporated to improve product life if required.
