DSA Flange will be used where there is a restriction of space on drill string. It provides an ideal solution by hooking up two different equipments of different size and pressure rating.
Specialty Drilling Tools offers Adapter Flanges and Adapter Spools in combinations that allow the connection of API flanges to those found in ANSI, ASTM, ASME, and MSS specifications.
We manufacture Adapter Spools in every size and pressure rating. Adapter Spools have end connections that differ from one another in nominal sizes and/or pressure rating.
