Vallourec is a pioneer and the uncontested industry leader in premium threaded connections for Top Tension Riser systems. We provide top-performing fatigue-enhanced connections which count with extensive track records in most waters of the world, in particular in the US Gulf of Mexico.
Our solutions allow for high-strength, fatigue-enhanced and light-weight high-performing Top Tension Riser strings.
Fatigue: sea haul induces cyclic movements of the platform/ vessel and to the Riser string itself and VAM® Risers connectors are designed for high-fatigue applications.
Sour Service: specific materials for production casing applications where the string may be submitted to H2S environment.
High Pressure: Internal Production pressures might reach 20 ksi on the deepest offshore wells.
Tension: high tension capacity is required to keep the Riser string in place.
Light-weight: save string weight thanks to the high yield pipes with thinner wall
Lines: VAM TOP® FE, VAM® TTR, and VAM® DR-HWcover all Drilling, Production and
Completion/ Workover Risers applications.
design: dedicated engineering teams, advanced Finite Elements Analysis (FEA)
and specific testing facilities allow us qualifying our VAM® Risers connections
per the most stringent protocols like ISO 13679, API RP 5C5, API 17G, ISO
13628-7, or any other customer own specification.
performance connections such as VAM® TTR or VAM® TTR HW (Heavy Wall) that provide excellent fatigue and operational
performance, allowing for a high number of Make-and-Breaks.
range of steel grades: Sour Service and High Strength materials are available in a vast range of
external diameters, from 7” to over 22”.
provide you with anti-corrosion solutions such as TSA OD-coatings and
ID-coatings that prevent both corrosion and excessive wear.
