Abstract

A system includes an enclosure defining an inner volume comprising a blast-resistant material having a metallic layer, wherein the metallic layer has substantially zero elongation, and a polymer layer coupled to the metallic layer and a pressure containing component disposed within the inner volume of the enclosure.

First claim

The invention claimed is:

1. A system, comprising:
an enclosure having a wall disposed about an inner volume, wherein the wall comprises a blast-resistant material, comprising:
a metallic layer, wherein the metallic layer has substantially zero elongation; and
a polymer layer coupled to the metallic layer; and

a fluid pressure containing component disposed within the inner volume of the enclosure, wherein an exterior surface of the fluid pressure containing component faces an interior surface of the enclosure, the wall comprising the blast-resistant material is a pliable sheet to conform to a shape of the fluid pressure containing component, and the enclosure is separable or at least partially spaced apart from the fluid pressure containing component;
wherein the blast-resistant material completely blocks and absorbs energy from one or more projectiles resulting from a blast event caused by a structural failure of the fluid pressure containing component due to internal fluid pressure, wherein the blast-resistant material distributes the energy across the metallic layer, and polymer layer further absorbs the energy and helps resist fragmenting of the metallic layer.

2. The system of claim 1 , wherein the metallic layer comprises a reinforcing material distributed within a matrix material.

3. The system of claim 2 , wherein the reinforcing material comprises a plurality of spherical glassfibers.

4. The system of claim 2 , wherein the matrix material comprises aluminum, and the reinforcing material comprises a plurality of fibers.

5. The system of claim 4 , wherein the wall comprising the blast-resistant material comprises a corrosion resistant layer coupled to the metallic layer.

6. The system of claim 5 , wherein the corrosion resistant layer is disposed between the metallic layer and the polymer layer.

7. The system of claim 1 , wherein the fluid pressure containing component comprises a valve, a choke, a mineral extraction tree, or any combination thereof, configured to flow a fluid along a fluid flow path, wherein the interior surface of the enclosure is at least partially spaced apart from the exterior surface of the fluid pressure containing component.

8. The system of claim 1 , wherein the enclosure comprises a plurality of panels each comprising the blast-resistant material, the enclosure comprises one or more support structures, and each support structure comprises first and second panel receptacles to receive respective first and second panels of the plurality of panels.

9. The system of claim 1 , wherein the blast-resistant material excludes ceramic materials.

10. The system of claim 1 , wherein the structural failure comprises breakage of the fluid pressure containing component into pieces defining the one or more projectiles being forced away from the fluid pressure containing component toward the wall comprising the blast-resistant material.

11. The system of claim 1 , wherein the pliable sheet comprises a blanket, and the pliable sheet is separable from the fluid pressure containing component.

12. A system, comprising:
a mineral extraction component having a fluid cavity; and
a pliable sheet having a wall comprising a blast-resistant material disposed at least partially about and spaced apart from an exterior surface of the mineral extraction component, wherein the pliable sheet conforms to a shape of the mineral extraction component, wherein the wall of the blast-resistant material comprises:
a first metallic layer comprising a matrix material and a reinforcing material distributed within the matrix material, wherein the first metallic layer is configured to absorb and distribute a force caused by structural failure of the mineral extraction component due to a fluid pressure in the fluid cavity; and
a first polymer layer coupled to the first metallic layer, wherein the first polymer layer is configured to help protect the first metallic layer from breaking into multiple pieces in response to the force caused by the structural failure of the mineral extraction component.

13. The system of claim 12 , wherein the reinforcing material comprises a plurality of spherical glass fibers, and the matrix material comprises aluminum.

14. The system of claim 12 , wherein the mineral extraction component comprises a valve, a choke, a mineral extraction tree, or any combination thereof, configured to flow a fluid along a fluid flow path having the fluid cavity, wherein the wall is separable from the mineral extraction component.

15. The system of claim 12 , wherein the wall comprising the blast-resistant material comprises a first corrosion resistant layer disposed between and coupled to the first metallic layer and the first polymer layer.

16. The system of claim 12 , wherein the wall comprising the blast-resistant material comprises a second corrosion resistant layer disposed between and coupled to the first metallic layer and a second polymer layer, wherein the first and second corrosion resistant layers are disposed on opposite sides of the first metallic layer, wherein the first and second polymer layers are disposed on the opposite sides of the first metallic layer.

17. A method, comprising:
positioning a surface of a pliable sheet comprising a blast-resistant material at least partially about an exterior surface of a mineral extraction component, wherein the pliable sheet comprising the blast-resistant material is separable from the mineral extraction component or at least partially spaced apart from the exterior surface of the mineral extraction component, wherein the pliable sheet conforms to a shape of the mineral extraction component;
pressurizing an inner volume of the mineral extraction component with a pressurized fluid until a pressure-containing performance of the mineral extraction component degrades; and
containing at least one projectile resulting from breakage of the mineral extraction component with the blast-resistant material after the pressure-containing performance of the mineral extraction component degrades.

18. The method of claim 17 , wherein containing the at least one projectile with the blast-resistant material comprises converting kinetic energy of the at least one projectile into thermal energy with one or more first layers of the wall, and protecting the one or more first layers of the wall from breaking into multiple pieces with one or more second layers of the wall.

19. The method of claim 17 , wherein the blast-resistant material comprises a metallic layer and a polymer layer coupled to the metallic layer, wherein the metallic layer has substantially zero elongation.

20. The method of claim 17 , wherein the pliable sheet is separable from the mineral extraction component and at least partially spaced apart from the exterior surface of the mineral extraction component, and the pliable sheet comprises a blanket.
