Abstract
A variable ram for a blowout preventer is disclosed. The variable ram includes a ram block and a ram packer assembly disposed at least in part within the ram block. The ram packer assembly includes a plurality of inserts and a packer member. The plurality of inserts is configured to form an insert array, where the insert array includes a peripheral surface, and where the peripheral surface of the insert array is disposed facing an opening configured to receive a tubular member. The packer member is coupled to at least a portion of the plurality of inserts for providing a unitary structure to the ram packer assembly, where the packer member protrudes from the peripheral surface of the insert array into the opening to define a bore face of the variable ram, and where the packer member includes an elastomeric material.
