U, UL and UM BOP Variable Bore Rams<br />
(VBR and VBR-II )<br />
The Cameron VBR-II is the next generation of the highly popular Cameron variable bore ram (VBR)<br />
packer. The patent pending VBR-II accomodates a range of pipe sizes and may be used in existing<br />
Cameron variable bore rams. The VBR-II seals on a range of drill pipe sizes as well as hexagonal kellys<br />
and provides uniform sealing pressure with virtual elimination of extrusion paths.<br />
As indicated in the chart below, the VBR-II is the standard VBR in most common sizes. In sizes where<br />
the VBR-II is not specified in the chart, the popular Cameron VBR is the standard offering. VBR-II<br />
packers for other size BOPs and other pipe size ranges are available upon request.<br />
