ASME I is the ASME code for power boilers + boiler external piping construction. This guide decodes inspection scope, NDE methods, weld acceptance, and code-specific gotchas.
\nASME I covers power boilers + boiler external piping construction. Boundaries: defined start/end conditions per the code's scope section. Excluded: items covered by other codes (e.g. ASME VIII for pressure vessels).
\nASME I specifies acceptance criteria for indications: linear/rounded limits, cluster rules, length × thickness ratios. Code-specific tables differ from generic ASME V. Inspectors must reference the correct code section.
\nPer ASME Section IX — WPS / PQR / welder qualification. Essential variables per the specific process (SMAW, GMAW, GTAW, FCAW, SAW). Continuity log per ASME I-specific requirements.
\n| Service / Concern | Recommended Method | Code Reference |
|---|---|---|
| Original construction welds | RT or UT | ASME I + ASME V Article 2/4 |
| Surface cracks (ferro) | MT | ASME V Article 7 |
| Surface cracks (non-ferro) | PT | ASME V Article 6 |
| In-service thickness monitoring | UT-T | ASME V Article 5 |
| Crack-like subsurface | PAUT or TOFD | ASME V Article 4 + Mandatory Appendices |
ASME I sets construction + initial inspection requirements. In-service inspection follows API 510 / 570 / 653 + state jurisdictional rules.
\nA: Every inspection, procedure revision, inspector qualification record and calibration certificate is timestamped with reviewer approval recorded in Atlantis NDT ERP, and kept for the period the governing code, regulator or client requires.
\nA: Methods (UT/RT/MT/PT/VT) are the same; ACCEPTANCE CRITERIA differ. Reference the specific code's acceptance section.
\nA: Yes — global delivery, ASNT NDT Level III + ASME I-qualified inspectors. Free consultation + tailored quote.
\nA: Per-asset 3D model with inspection-data overlay, weld register, repair history, NDT signatures. Pressure-equipment register integrated.
\nA: ASNT NDT Level II + API 510/570/653 where applicable.
\nA: ASME I-specified retention, typically life-of-equipment. Atlantis NDT ERP stores all records SHA-256 hashed.
\nA: Inspector + welder qualification typically 3-6 months. Atlantis NDT 5-day cohorts accelerate the path.
\nA: Yes — ASNT NDT Level III led discovery + scope sizing + tailored quote. request a free consultation.
\n\n\nRecommended practices and guides inform an inspection programme; binding requirements come from the in-service codes (API 510, API 570, API 653), the construction codes and the regulations that apply to the asset. NDE personnel are qualified under the employer's written practice (commonly ASNT SNT-TC-1A, ANSI/ASNT CP-189 or ISO 9712), and NDE procedures are approved by the employer's NDT Level III. Acceptance of indications follows the governing code; damage beyond its rules may be referred for an engineering fitness-for-service assessment (API 579-1/ASME FFS-1), which Atlantis NDT does not perform. Keep procedure revisions, calibration records and personnel certifications traceable; Atlantis ERP can hold these records.
\nUse the edition required by the contract, governing requirements and applicable jurisdiction. Record that edition in the procedure and evaluate changes before adopting a later publication.
\nA: 4-20 weeks depending on team size + scope. SMB: 4 weeks. Mid-size: 8-12 weeks. Enterprise multi-region: 12-20 weeks. Atlantis NDT delivers phased rollout with clear milestone gates.
\nA: Atlantis ERP has an open REST API, so it connects to SAP, Maximo, NetSuite or any other system that accepts API connections; each integration is scoped with you during implementation. Free integration scoping consultation.
\nA: Request a free 30-min consultation at /contact. We reply within one business day. We scope your asset class + damage mechanisms + code requirements + delivery model preference + integration needs in a single call.
