Pressure test containment vessel
View Patent ↗A portable containment vessel to perform a pressure test to a test specimen includes a base skid, a ballistic outer enclosure connected to the base skid and comprising a plurality of walls, a door, and a lock to maintain the door in a closed position, a sample tray configured to support the test specimen, wherein the sample tray is operable through a doorway of the ballistic outer enclosure between a retracted position and an extended position, a containment fluid to surround the test specimen while a pressurized test fluid is applied to the test specimen, and a sensor to indicate a failure of the pressure test.
1. A portable containment vessel to perform a pressure test to a test specimen, the portable containment vessel comprising:
a base skid;
a ballistic outer enclosure connected to the base skid and comprising a plurality of walls, a door, and a lock to maintain the door in a closed position;
a sample tray configured to support the test specimen, wherein the sample tray is operable through a doorway of the ballistic outer enclosure between a retracted position and an extended position;
a containment fluid to surround the test specimen while a pressurized fluid is applied to the test specimen;
a sensor to indicate escape of the pressurized fluid from the test specimen; and
at least one fluid tight polymeric membrane positioned within the ballistic outer enclosure, wherein the at least one fluid tight polymeric membrane allows the test specimen to be monitored while the door of the ballistic outer enclosure is open.
2. The portable containment vessel of claim 1 , wherein the at least one fluid tight polymeric membrane is positioned adjacent to the door of the ballistic outer enclosure, and is retractable to allow access to an interior volume when the door is in an open position.
3. The portable containment vessel of claim 1 , further comprising a manifold assembly to selectively apply the pressurized test fluid to the test specimen.
4. The portable containment vessel of claim 1 , wherein the sensor comprises a camera.
5. The portable containment vessel of claim 1 , wherein the sensor comprises a pressure gauge.
6. The portable containment vessel of claim 1 , wherein the sensor is configured to detect a presence of the test fluid in the containment liquid.
7. The portable containment vessel of claim 1 , wherein the containment fluid comprises water.
8. The portable containment vessel of claim 1 , wherein the containment fluid comprises drilling mud.
9. The portable containment vessel of claim 1 , wherein the containment fluid comprises a gas.
10. The portable containment vessel of claim 1 , further comprising a pump to supply the containment fluid to an interior volume of the ballistic outer enclosure.
11. The portable containment vessel of claim 1 , further comprising a heater to increase the temperature of the test specimen.
12. A method to test the internal pressure integrity of a test specimen, the method comprising:
positioning the test specimen inside a ballistic outer enclosure;
connecting the test specimen to a test fluid supply;
sealing the test specimen within the ballistic enclosure with at least one fluid-tight polymeric membrane;
filling the ballistic enclosure with a containment fluid;
increasing a pressure of the test fluid supply to a desired test pressure; and
monitoring the test specimen through the fluid-tight polymeric membrane while a door of the ballistic outer enclosure is open to determine its internal pressure integrity.
13. The method of claim 12 , further comprising positioning the test specimen inside the outer enclosure with an extendable sample tray.
14. The method of claim 12 , wherein the fluid-tight polymeric membrane is transparent, semi-transparent, or partially opaque.
15. The method of claim 12 , further comprising monitoring the test specimen with a camera.
16. The method of claim 12 , further comprising monitoring the test specimen with a sensor configured to detect the presence of the test fluid in the containment fluid.
17. The method of claim 12 , further comprising heating the test specimen.
18. The method of claim 12 , further comprising:
testing the test specimen at a first test pressure using a first test fluid supply and a first containment fluid; and
testing the test specimen at a second test pressure using a second test fluid supply and a second containment fluid.
19. A containment vessel to perform a pressure test to a test specimen, the containment vessel comprising:
a base skid;
a ballistic outer enclosure connected to the base skid;
at least one fluid-tight polymeric membrane positioned within the ballistic outer enclosure, wherein the at least one fluid tight polymeric membrane allows the test specimen to be monitored while a door of the ballistic outer enclosure is open;
a manifold assembly configured to selectively apply a pressurized test fluid to the test specimen;
a containment fluid to surround the test specimen, the test specimen within the ballistic outer enclosure and the at least one fluid-tight polymeric membrane while the pressurized test fluid is applied to the test specimen; and
a sensor to indicate escape of the pressurized test fluid from the test specimen.
20. The containment vessel of claim 19 , wherein a first of the at least one fluid tight polymeric membrane is positioned adjacent to the door of the ballistic outer enclosure and is retractable to allow access to an interior volume when the first of the at least one fluid tight polymeric membrane is in an open position.
21. The containment vessel of claim 19 , further comprising a sample tray to support the test specimen, wherein the sample tray is operable through a doorway of the ballistic outer enclosure between a retracted position and an extended position.
