Owner-Inspector Services for ASME B31 Piping Systems
When your facility installs, alters, or repairs piping systems under ASME B31.1, B31.3, or B31.5, an independent Owner-Inspector ensures the work meets code before problems become costly. PowerTech Consulting provides full Owner-Inspector services for power piping, process piping, and refrigeration piping — reviewing design, verifying materials, and witnessing critical construction steps on your behalf.
What Each Code Covers
ASME B31.1 — Power Piping
Covers piping systems in electric power generating stations, industrial plants, geothermal systems, and heating/cooling systems.
ASME B31.3 — Process Piping
Covers piping at refineries, chemical plants, pharmaceutical facilities, and similar processing operations — one of the most widely applied piping codes in industry.
ASME B31.5 — Refrigeration Piping
Covers piping systems for refrigeration plants and ammonia refrigeration systems.
Owner-Inspector Scope of Services
- Acting as the Owner's designated Inspector for piping systems under B31.1, B31.3, and B31.5
- Reviewing design documentation, P&IDs, isometrics, and construction drawings
- Verifying material selection, Material Test Reports (MTRs), and code compliance/traceability
- Witnessing weld fit-up and welding activities
- Reviewing and accepting pressure test records
- Confirming that examination, inspection, and testing requirements under the applicable code are met before system acceptance
Why an Independent Owner-Inspector Matters
Under ASME B31 codes, the Owner's Inspector cannot be an employee of the manufacturer, fabricator, or erector — the role must be independent of the parties doing the work. PowerTech Consulting acts as your independent, qualified representative, giving you confidence that inspection, examination, and testing are being verified objectively, not signed off by the same team doing the installation.
Who This Is For
- Facilities installing, altering, or repairing piping under B31.1, B31.3, or B31.5
- Owners who need an independent inspector separate from their installation contractor
- Hospitals, plants, and municipal facilities managing process, power, or refrigeration piping systems
Can the same company that installs our piping also act as our Owner's Inspector?
No — under ASME B31 codes, the Owner's Inspector must be independent of the manufacturer, fabricator, or erector. PowerTech Consulting acts as that independent inspector on your behalf.
Do you provide Owner-Inspector services for refrigeration piping specifically?
Yes. We provide Owner-Inspector services under ASME B31.5 for refrigeration piping, including ammonia refrigeration systems.
