High-pressure hydrogen test fixture
| DWPI Title: High-pressure hydrogen test fixture testing performance of pressure seals in high-pressure hydrogen environment, has inlet port and inlet channel supplying pressurized hydrogen to test chamber during test operation, where hydrogen pressurizes test article to test seal |
| Abstract: A high-pressure hydrogen test fixture includes a main body having a test cavity, a flange covering the test cavity when attached to the main body to thereby form a test chamber, a plurality of flange bolts and corresponding nuts to attach the flange to the main body, a flange seal arranged in a seal groove of the main body, an inlet channel between the test chamber and an inlet port, a vent channel between the test chamber and a vent port, and a sample carrier. The flange seal forms a seal between a sealing surface of the flange and the seal groove of the main body. The sample carrier has at least one of a face seal groove and a radial seal groove for receiving a test article. A seal formed by the test article and the test fixture is arranged between the inlet channel and the vent channel. |
| Use: High-pressure hydrogen test fixture for testing the performance of pressure seals in a high-pressure hydrogen environment. |
| Advantage: The fixture allows for testing applicability of materials with respect to pressurized hydrogen gas, and emulates operating conditions to which the materials is to be subjected. Multiple exemplary test fixtures can be attached to in a high pressure gas manifold via standard connections to provide for testing additional polymer seals. |
| Novelty: The fixture (100) has a main body (102) with a test cavity, and a flange (110) that covers the test cavity of the main body when the flange is attached to the main body to form a test chamber. A set of flange bolts extend through at least one of the flange and the main body for securing the flange to the main body via a set of corresponding nuts. A flange seal is arranged in a seal groove of the main body. The flange seal forms a seal between a sealing surface (118) of the flange and the seal groove of the main body when the flange is attached to the main body. An inlet channel (144) is in fluid communication with the test chamber and an inlet port. A vent channel is in fluid communication with the test chamber and a vent port (128). A sample carrier (106) has at least one of a face seal groove and a radial seal groove (142) for receiving a test article. |
