Abstract:
1. A wear insert for a ram packer for axially slidable engagement in a ram packer of a blowout preventer comprising: (a) a sealing surface having a semicircular face and (b) a ram packer mounting surface having a multi-sided configuration having a first pair of parallel sides having terminal ends, second pair of parallel sides, a pair of non parallel sides extending from said second pair of parallel sides, said non parallel sides having terminal ends distal to said second pair of parallel sides, a first area defined by a plane through said terminal ends of said non parallel sides and said first pair of parallel sides and at least one projection for spacing said wear insert away from a seating surface of a ram packer said projection terminating in a second area, said second area being less than said first area, and said projection extending from said first area, wherein said projection does not prevent rotation of said wear insert, while allowing for elastomer flow through the ram packer even when the configured shoulders would otherwise be fully compressed against the back of the ram packer.
