VAM TOP® FE is a threaded and coupled riser connector featuring high fatigue resistance (SAF ≤ 2.0 vs. DNVB1 curve). It is the "Fatigue Enhanced" version of the widely used and field proven VAM TOP® connection.
VAM TOP® FE features a premium gas tight internal metal-to-metal seal identical to the famous premium casing/tubing connection VAM TOP® from which it was designed. Fatigue enhancements include a bending swoosh to provide more flexibility in bending, a smooth thread shape, and increased coupling OD versus VAM TOP®.
VAM TOP® FE has been the standard for riser applications for the last decade with over 1,000,000ft run throughout the world.
