Customer Meters, Regulators, and Service Lines (12)
Criticality: Medium
Progress: Not Addressed
Score: 24
DOT Relevance: §192.351 – §192.383
Description of Key Area
Subpart H (Customer Meters, Service Regulators, and Service
Lines) of 49 CFR 192 “prescribes minimum requirements for installing customer
meters, service regulators, service lines, service line valves, and service
line connections to mains.
Discussion of Criticality
The criticality is listed as medium because distribution mains
are considered to be the highest priority, and sequentially the first item to
be addressed when changing from gas pipelines to hydrogen pipelines.
Discussion of Progress
No information found.
Recommendations
ASME B31.12 requirements are the same as those for ASME B31.8. Different
pressures for hydrogen service may require special attention. It is presumed
that any unique requirements would be derived from natural gas standards. Standards
for hydrogen pipelines should be established and incorporated by reference into
the federal code.
