Blowout Preventer with High-Temperature Pipe Ram Assembly

摘要

A pipe ram blowout preventer (“BOP”) may be used for sealing about an object positioned in a vertical bore extending through the BOP. The BOP includes a pipe ram assembly movable towards the tubular, the pipe ram assembly including a packer assembly comprising an elastomeric body for sealing against the object. The packer assembly includes a packer insert within the elastomeric body, the packer insert comprising a generally interlaced structure, such as a wire mesh. The packer insert reduces deleterious effects of using a pipe ram assembly in high temperature environments by resisting crumbling of the elastomeric material when it becomes brittle.

主权项

1. A packer assembly for a pipe ram blowout preventer (“BOP”) configured to seal about an object located in a vertical bore of the BOP, the packer assembly comprising:
a body comprising:
an elastomeric material and a curved inner surface configured to engage the object; andan insert comprising an interlaced structure locatable within the body and configured to diminish deterioration of the elastomeric material.
