Burst (14.5)

Criticality: High
Progress: Addressed, Not Adequately
Score: 20
DOT Relevance: §192.501 – §192.517

Description of Key Area

Material testing falls under Subpart J (Test Requirements) of 49 CFR 192. Per the Code, “This subpart prescribes minimum leak-test and strength-test requirements for pipelines.”

Discussion of Criticality

Burst testing is one mechanism to verify design parameters and assumptions.

Discussion of Progress

SRNL recommends that mechanical tests for materials to be used for hydrogen service include burst testing.

Recommendations

Burst testing as a topic is not covered in ASME B31.12. Standards for burst testing of materials and structures to be used for hydrogen pipelines should be established and incorporated by reference into the federal code.
