VAM® MUST™

VAM® MUSTTM is a flush integral heavy wall premium connection for floating salt formations​ and high collapse applications. VAM® MUSTTM is intended to be used in a combined string (VAM® T&C x VAM® MUSTTM with increased pipe OD adapted to the T&C OD x VAM® T&C).

VAM® MUSTTM is used in the section of the string where the highest collapse pressure occurs without changing the outside diameter and drift of the upper and lower string. VAM® MUSTTM is the reference for floating salt formations.

 Applicable range

  • Available in sizes of 5 1/2" (139,7 mm), 7 5/8" (193,68 mm) and  10 3/4" (273,05 mm)
  • Available wall thickness from 0,75" to 1,03" (19,5 mm to 26,16 mm)
  • Available in standard drifts
  • Available in grades according API 5CT / Vallourec Proprietary Grades including High Collapse, Sour Service and Low Temperature grades
  • Available in several CRA​ grades​
  • Available in yield strengths from 80 ksi (551,6 MPa) to 140 ksi (965,3 MPa).

 Applications

Designed for floating salt formations:

  • Intermediate string
  • Combined string
  • Production casing​.


 

 

 Performances

  • Withstand extreme external pressure
  • Internal gas sealability / external hydraulic sealability
  • Bending validated up to 10°/100ft
  • Extreme shear resistance and collapse resistance due to thick wall pipe.
 

 Benefits

 

  • Heavy wall for maximum collapse resistance
  • Internally / externally fully flush
  • Gas tight under combined load
  • Same OD and ID as lower and upper string section results in same drilling parameters
  • Easy stabbing and running.​
