Abstract

A pipe restraint assembly includes a restraint body configured to be removably attached to a portion of pipe. The portion of pipe is associated with a postulated pipe failure associated with a release of high pressure fluid. A plurality of apertures penetrate through the restraint body and are positioned proximate to a location of the postulated pipe failure. The apertures are configured to provide a number of passageways for the fluid to exit from the location of the postulated pipe failure and to be released outside of the restraint body. One or more restraint devices maintain the position of the apertures relative to the location of the postulated pipe failure.

First claim

The invention claimed is:

1. A pipe restraint assembly, comprising:
a restraint body configured to be removably attached to a portion of pipe, wherein the portion of pipe is associated with a postulated pipe failure associated with a release of high pressure fluid;
a plurality of apertures that penetrate through the restraint body and are positioned proximate to a location of the postulated pipe failure;
one or more pipe restraints permanently attached to the pipe and extending out from an exterior surface of the pipe, wherein at least one of the one or more pipe restraints extends into at least one of the apertures to maintain the position of the apertures relative to the location of the postulated pipe failure.

2. The pipe restraint assembly of claim 1 , including a ridge formed along at least a portion of the circumference of the pipe, wherein the restraint body comprises a groove formed on an interior surface of the restraint body, and wherein the groove is configured to fit around the ridge.

3. The pipe restraint assembly of claim 2 , wherein the ridge is formed from built-up weldment material formed on the surface of the portion of pipe.

4. The pipe restraint assembly of claim 2 , wherein the ridge comprises a pipe flange configured to join to portions of pipe together.

5. The pipe restraint assembly of claim 1 , further comprising an annular gap formed between an exterior surface of the pipe and an interior surface of the pipe restraint system, wherein the annular gap interconnects the plurality of apertures to the location of the postulated pipe failure.

6. The pipe restraint assembly of claim 5 , wherein the annular gap encompasses the circumference of the exterior surface of the pipe.

7. The pipe restraint assembly of claim 1 , wherein the restraint body comprises two partial cylindrical portions, wherein the two partial cylindrical portions are mounted together around the pipe to form the restraint body, and wherein each partial cylindrical body comprises one or more of the plurality of apertures configured to controllably release the fluid outside of the restraint body.

8. The pipe restraint assembly of claim 7 , further comprising two endplates attached to either end of the restraint body, wherein the endplates are oriented perpendicular to the axis of the pipe, and wherein the pipe passes through the approximate center of both endplates.

9. A pipe restraint assembly, comprising:
a restraint body configured to be removably attached to a portion of pipe, wherein the portion of pipe is associated with a postulated pipe failure associated with a release of high pressure fluid;
a plurality of apertures that penetrate through the restraint body and are positioned proximate to a location of the postulated pipe failure, wherein the apertures are configured to provide a number of passageways for the fluid to exit from the location of the postulated pipe failure and be released outside of the restraint body; and
one or more pipe restraints, wherein at least one of the one or more pipe restraints extends into at least one of the apertures to maintain the position of the apertures relative to the location of the postulated pipe failure, wherein the one or more pipe restraints each comprise a stud that is welded to the exterior surface of the pipe, and wherein the stud extends into one of the apertures.

10. A pipe restraint assembly, comprising:
a restraint body configured to be removably attached to a portion of pipe, wherein the portion of pipe is associated with a postulated pipe failure associated with a release of high pressure fluid;
an aperture that penetrates through the restraint body and is positioned proximate to a location of the postulated pipe failure, wherein the aperture is configured to provide a passageway for the fluid to exit from the location of the postulated pipe failure and be released outside of the restraint body; and
a pipe restraint permanently attached to the pipe and extending out from an exterior surface of the pipe and into the aperture to maintain a position of the aperture relative to the location of the postulated pipe failure.

11. The pipe restraint assembly of claim 10 , wherein the pipe restraint comprises a stud that is welded to the exterior surface of the pipe and extends into the aperture.

12. The pipe restraint assembly of claim 10 , including a ridge formed along at least a portion of the circumference of the pipe, wherein the restraint body comprises a groove formed on an interior surface of the restraint body, and wherein the groove is configured to fit around the ridge.

13. The pipe restraint assembly of claim 12 , wherein the ridge is formed from built-up weldment material formed on the surface of the portion of pipe.

14. The pipe restraint assembly of claim 10 , wherein the restraint body comprises two partial cylindrical portions, wherein the two partial cylindrical portions are mounted together around the pipe to form the restraint body, and wherein one of the cylindrical portions forms the aperture configured to controllably release the fluid outside of the restraint body.

15. The pipe restraint assembly of claim 10 , including an opening formed between the aperture and a periphery of the pipe restraint when the aperture extends out into the aperture, the opening configured to provide a passageway for the fluid to exit from the location of the postulated pipe failure and be released outside of the restraint body.
