T and TL BOP Variable Bore Rams<br />
One set of variable bore rams seals on several sizes of pipe or hexagonal kelly. Variable bore rams are<br />
available in the size ranges listed in the chart below. All rams listed are suitable for H 2 S service per NACE<br />
MR-01-75.<br />
CAMRAM packers and top seals are standard for all T and TL BOP variable bore rams. The variable bore<br />
ram packer contains steel reinforcing inserts similar to those in the Cameron annular BOP packer. The<br />
steel inserts rotate inward when the rams are closed so that the steel provides support for the rubber<br />
which seals against the pipe.<br />
