Pipe Rams

Fixed-size sealing of tubulars

BroadShear Ram Shearing

By maximizing sealing durability, Cameron pipe rams bring enhanced certainty and HSE profiles to drilling and production operations.

The rams are designed so that the packer, top seal, and ram body act in unison to form one half of a ram cavity’s seal. The packers extend forward of the ram body faces.

When the rams are closed, the packers contact each other on the leading surfaces at the sides of the pipe bore. As the rams continue to close, the rubber in the packers is displaced inward to close the packers around the pipe.
