The UROS-SUB centralizer is designed to be run in the close tolerance, under-ream applications found in some of the world’s most challenging deepwater wells.
The UROS-SUB centralizer is designed to be run in the close tolerance, under-ream applications found in some of the world’s most challenging deepwater wells.
The UROS-SUB’s single piece centralizer reduces the risk of failure in high profile applications. This engineered solution enables the centralizer to rotate on the sub body with minimal torque values.
The UROS centralizer recesses into the sub body during RIH allowing it to pass through the tightest of restrictions.
The sub body, manufactured to API 5CT requirements, will meet or exceed burst, collapse and tensile ratings and will be threaded to fit the casing string.
Centek has the capability to supply sub bodies tailored to meet customer specifications.
