A practical evidence checklist for RFQ preparation and supplier evaluation.
CNFX does not score or rank suppliers. Buyers must verify all claims and documents with the legal manufacturer before ordering.
The design pressure range is 15–60 MPa, as per ASME BPVC Section VIII Div. 1. However, the exact value depends on the specific reactor model and application, so it must be confirmed with the legal manufacturer or supplier.
Common materials include low-alloy steel, stainless steel cladding, and high-temperature alloys. The material grade specified is SA-387 Gr.22 Cl.2 (ASTM A387), which is a Cr-Mo steel suitable for high-temperature hydrogen service.
The reactor uses internal cooling coils or interbed heat exchangers to manage the exothermic reaction heat. The heat transfer coefficient ranges from 200–500 W/(m²·K), and the operating temperature is maintained between 350–550 °C.
Key indicators include pressure drop across the reactor (0.1–0.5 MPa), leakage rate (≤0.1 %/year per ISO 15848-1), and corrosion allowance (3–6 mm). Regular inspection is necessary to ensure safe operation and prevent failures.
