8464785, Jun 18, 2013

Filed:

Dec 29, 2011

Appl. No.:

13/339519

Inventors:

William L. Carbaugh - Humble TX, US
Leonard G. Childers - Houston TX, US
Viral Shah - Houston TX, US

Assignee:

Hydril USA Manufacturing LLC - Houston TX

International Classification:

E21B 43/11
E21B 33/06

US Classification:

166 55, 166 854, 251 13

Abstract:

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.

US Classification:

166 55, 166 854, 427255394

Abstract:

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.

Inventors:

Viral Shah - Houston TX, US

Assignee:

HYDRIL USA MANUFACTURING LLC - Houston TX

International Classification:

E21B 29/00
B23P 11/00

US Classification:

166 55, 2952511

Abstract:

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.

International Classification:

E21B 29/00
E21B 33/06

US Classification:

166 55, 166 854

Abstract:

A shear ram assembly including upper and lower ram blocks having blades positioned on opposing sides of pipe and other, more ductile items, and arranged to close around and shear the pipe and the more ductile items. The shear ram assembly includes pipe guide arms attached to the upper ram block and configured to guide pipe and other items into the path of the blades, and to be received by recesses in the lower ram block. Also included are wear plates mounted on top of the pipe guide arms and positioned to force the lower ram block to rise as the arms enter the recesses, thereby causing the gap between the blades to decrease so that the blades can better shear the more ductile items.
