Code and jurisdiction
- Applicable code: ASME BPVC Section VIII (Div 1, 2, or 3)
- EU market: PED/CE if applicable
- Canada: CRN if applicable
- Inspection: note any third-party or Authorized Inspector witnessing requirements
Drawing package or inputs
Provide a GA drawing with the RFQ if available, or share inputs so we can develop one:
- Vessel tag number
- Orientation: horizontal or vertical
- Supports: skirt, saddle, or legs
- Shell and head dimensions; overall length
- Head type: 2:1 ellipsoidal, hemispherical, torispherical, or flat
- Design conditions called out on the drawing
- Weights: empty and operating
Nozzle schedule details
- Nozzle tag (e.g., N1, N2)
- Nominal pipe size (NPS)
- ASME B16.5 pressure class rating
- Flange face type: RF, RTJ, or FF
- Orientation angle from vessel centerline
- Elevation from tangent line or a defined datum
NDE and testing scope
- NDE methods: RT, UT, PT, MT
- Hydrostatic test
- Witnessing requirements if applicable
Documentation package tier
- Basic: as-built GA drawing and ASME calculations
- Full: as-built GA drawing, ASME calculations, MTRs (heat-traceable when required), test procedures and results, hydrostatic test report, NDE reports, weld maps, ASME Form U-1 (for Section VIII, Div 1 code-stamped vessels)
Scope boundaries (quoting clarity)
State what is outside the vessel scope (e.g., controls, external piping, instrumentation, installation) unless explicitly included in the RFQ.
Test and Documentation Deliverables
Request the deliverables your project requires in your RFQ or PO. See the RFQ guide: how to prepare an RFQ and spec package for pressure vessels.
| Deliverable | When to request | Notes |
|---|---|---|
| As-built GA drawing | Always (Basic or Full) | GA is updated to as-built and included in final docs |
| ASME design calculations | Always (Basic or Full) | Matches selected ASME Section VIII division |
| Material Test Reports (MTRs) | Full or code-stamped work | May require heat-number traceability |
| Test procedures and results | Full | Covers tests performed per RFQ scope |
| Hydrostatic test report | Full | Confirms hydrostatic test completion and results |
| NDE reports (RT, UT, PT, MT) | When NDE is specified | Aligns with defined NDE scope in RFQ |
| Weld maps | Full | Weld identification and traceability |
| ASME Form U-1 | For Section VIII, Div 1 code-stamped vessels | Manufacturer’s Data Report at closeout |
Include the vessel’s application, operating and design conditions, materials, dimensions, connections and applicable code requirements. Share available drawings, testing and documentation needs, quantity and delivery schedule. Identify any accessories or engineering support needed so the quote reflects the complete scope.
Confirm both quotes cover the same materials, design requirements, inspections, testing and documentation. Compare exclusions, delivery timelines, freight and engineering costs alongside price. Ask suppliers to clarify scope differences in writing so a lower price does not hide missing requirements.
You can specify material test reports, pressure-test reports, weld maps and nondestructive examination records. Depending on project requirements, additional records may cover leak testing, dimensional inspections, heat treatment and the applicable ASME manufacturer’s data report. Define documentation needs in the RFQ.
