Publication number: 20170254167Abstract: A BOP packer, including a body disposed about a longitudinal axis and adapted to be compressed upon energization of the packer, and an insert having a form symmetrical about a plane parallel to the longitudinal axis, and embedded in the body with the body adhered to the insert to reduce extrusion of the body when the packer is energized. The insert includes an upper flange and a lower flange, each having a wedge-shaped configuration that expands from a relatively narrow portion at the end nearest the longitudinal axis, to a relatively wide portion at an opposite end, and a web element extending between the upper flange and the lower flange. The web element defines an elongated aperture through which a portion of the elastomeric body passes to help maintain the position of the metallic insert relative to the body, and to reduce shear forces between the insert and the body.Type: ApplicationFiled: March 2, 2016Publication date: September 7, 2017Inventor: William L.

Patent number: 8844613Abstract: A shear blade attached to a ram block. At least one bolt passage is formed at an angle at the top of the ram block. A bolt passage is formed in the shear blade that corresponds with the bolt passage on the tam block. A bolt introduced into the bolt passage of the ram block and also the bolt passage in the shear blade attaches the shear blade to the ram block. By using this technique for attaching the shear blade to the ram block, surface area of a front face of the shear blade is not further reduced. Therefore, the strength of the shear blade is increased.Type: GrantFiled: December 28, 2011Date of Patent: September 30, 2014Assignee: Hydrill USA Manufacturing LLCInventors: Viral Shah, William L.

Publication number: 20140183382Abstract: A variable ram assembly for use in a blowout preventer (BOP) stack includes a packer element. The packer element includes an elastomeric body having a contact surface configured with a curved recess for sealing engaging a tubular. At least a portion of the body adjacent the contact surface is reinforced to define a reinforced area. The reinforced area exerts a restraining force to prevent extrusion of the elastomeric body when it is forced against the tubular. The reinforced area is integrally formed with the body using a molding process.Type: ApplicationFiled: May 20, 2013Publication date: July 3, 2014Applicant: Hydril USA Manufacturing LLCInventors: William L.

Publication number: 20140183381Abstract: A variable ram assembly for use in a blowout preventer (BOP) stack includes a packer element. The packer element includes an elastomeric body having a contact surface configured with a curved recess for sealing engaging a tubular. Fibers are included in the body adjacent the contact surface that exert a restraining force to prevent extrusion of the elastomeric body when it is forced against the tubular. The fibers are integrally formed in the body and may be woven into a fabric, which is disposed into a packer element mold along with uncured elastomer before forming the body. The fabric can be coated with an elastomer to bond with the body during the forming process.Type: ApplicationFiled: May 20, 2013Publication date: July 3, 2014Applicant: Hydril USA Manufacturing LLCInventors: William L.

Publication number: 20130153204Abstract: A shear ram assembly apparatus for providing the capability to shear larger diameter well casings and internal components during ram-type blowout preventer operation while requiring less force to perform the cutting. Components of the shear ram assembly apparatus, include but not limited to a plurality of hardened cutting blades that are coated with a compound that increases the hardness and reduces the coefficient of friction of the cutting blades. In this regard, a smaller force is required to perform the cutting and the cutting blades receive less wear per cut and provide greater assurance that each cut of this failsafe apparatus is successful.Type: ApplicationFiled: December 20, 2011Publication date: June 20, 2013Applicant: HYDRIL USA MANUFACTURING LLCInventors: William L. CARBAUGH, Leonard CHILDERS, Viral SHAH

Patent number: 8464785Abstract: A pipe shear ram assembly has a housing having a bore extending vertically therethrough for the passage of a pipe string. Ram blocks have blades positioned such that one slides over the other when the first and second ram blocks are moved toward each other to shear a well pipe. A pair of guide arms extend from one of the rams. The guide arms have tips protruding a greater distance than the blade. Each of the guide arms has an inboard wedge surface beginning at the tip and extending along a line that intersects the longitudinal axis for guiding the pipe string toward a bore axis of the bore in the event the first and second ram blocks are moved to the closed position.Type: GrantFiled: December 29, 2011Date of Patent: June 18, 2013Assignee: Hydril USA Manufacturing LLCInventors: William L.
