High-Temperature Variable-Bore Rams
H2S and high-temperature applications
Provide a seal to a range of diameters, and are suited for H2S service per NACE MR0175 and compatible with U surface ram-type BOP.
TL
Offshore ram-type BOP
Based on our experience with the U surface ram-type BOP, UII subsea ram-type BOP, and T-81 small-bore, compact ram-type BOP, the TL offshore ram-type BOP offers the same quality, reliability, and performance in a lighter design.
Our TL BOP helps decrease downtime by simplifying maintenance, featuring side ram removal and hydraulically opening bonnets that simplify ram changeout. Seal replacement does not require bonnet removal, and bonnet seal carriers eliminate the need for high makeup torque on bonnet studs and nuts. Access caps on the ram-change pistons also enable easier access from the end of the bonnet. For improved safety and performance, ST locks and wedge locks can be interlocked with the TL BOP operating system using sequence caps to ensure the lock is retracted before applying pressure to open the BOP.
