| Component | Material Standard / Typical Grade | Functional Role |
|---|---|---|
| Heat Exchanger Tubes (seamless) | ASME SA-213 TP316L | Low-carbon stainless steel; superior resistance to chloride pitting and general corrosion |
| Stationary Tubesheet | ASME SA-182 F316L (forged) | Fixed-end connection to shell; houses tube inlets/outlets |
| Floating Tubesheet | ASME SA-266 Gr.2 (carbon steel forging) | Not welded to shell; permits axial thermal movement |
| Shell & Shell Cover | ASME SA-516 Gr.70 (carbon steel plate) | Primary pressure boundary; thickness designed per ASME UG-27 |
| Channel & Channel Cover | ASME SA-516 Gr.70 or ASME SA-240 316L (plate) | Tube-side fluid containment; provides access to tube ends |
| Baffles | ASME SA-516 Gr.70 or ASME SA-240 316L | Support tubes and direct cross-flow for enhanced heat transfer |
| Floating Head Assembly | Cover, gasket, bolting - per ASME Section VIII | Enables bundle extraction and accommodates differential expansion |
| Test Type | Code Reference | Acceptance Criterion |
|---|---|---|
| Hydrostatic Test | UG-99 - 1.3 × MAWP, minimum 30‑min hold | No visible leakage or pressure decay; tested separately on shell and tube sides |
| Radiographic Examination (RT) | ASME Section V, Article 2 | Full or spot RT per UW-11; no unacceptable volumetric indications |
| Ultrasonic Examination (UT) | ASME Section V, Article 5 | Laminar inspection of plates and forgings; thickness verification |
| Dye Penetrant / Magnetic Particle (PT/MT) | ASME Section V, Articles 6 & 7 | Surface flaw detection on all pressure-retaining welds and machined surfaces |
| Pneumatic Test | Optional (when hydrotest not feasible) | Per ASME Code Case or user specification |
| Final Dimensional Check | Per approved fabrication drawings | All critical dimensions (tube pitch, baffle spacing, nozzle orientation) verified |
