Blowout preventer seal and method of using same

摘要

A blowout preventer (BOP) seal and method are provided. The seal includes a tubular body comprising a plurality of segments that form a continuous loop. The tubular body has a plurality of inner projections extending from opposite sides of a first end thereof and a plurality of outer projections extending from opposite sides of a second end thereof. Each of the plurality of projections tapers away from the tubular body. A cross-sectional area along at least a portion of the plurality of segments is varied whereby the plurality of segments are selectively reinforced.

1. A metal-to-metal seal, comprising:
a tubular body comprising a plurality of segments that form a continuous loop, a first portion of the plurality of segments being linear and a second portion of the plurality of segments being curved, the tubular body having a plurality of projections comprising a plurality of inner projections extending from opposite sides of a first end thereof and a plurality of outer projections extending from opposite sides of a second end thereof, each of the plurality of projections tapering away from the tubular body, the outer projections having an inner taper surface at an inner angle tapering away from the inner projections and an outer taper surface at an outer angle tapering towards the inner projections; wherein a cross-sectional area of the tubular body at a location along the first portion of the plurality of segments is different from a cross-sectional area of the tubular body at another location along the second portion of the plurality of segments whereby the plurality of segments are selectively reinforced.
