  • High-Strength Blowout Preventer Shearing Ram and Connecting Rod
    Publication number: 20160298409
    Abstract: A blowout preventer includes a housing, comprising a longitudinal bore extending therethrough and a cavity intersecting the bore, and pair of opposing shear rams configured to shear a tubular located in the longitudinal bore. The opposing shear rams can be moved radially into and out of the longitudinal bore by connecting rods coupled to the shear rams. The connecting rods may be coupled to the shear rams via intermediate connecting assemblies which may include a split-flange connector comprising multiple sections. The shear rams and/or the connecting rods may be constructed of a high-strength heat treatable, low alloy steel, such as AISI 4340 steel. The shear rams are constructed of a single material having a higher hardness than that of the tubular product.
