ASME SA266 Gr.2N 炭素鋼フランジ（石油化学設備用）

We installed this heat exchanger at our petrochemical facility in Jubail Industrial City back in March. The ASME VIII-1 certification was non-negotiable for us, and this unit delivered exactly what we needed. The SA516 Gr485 shell material has held up exceptionally well against our high-temperature process streams, even during the peak summer months when ambient temperatures exceed 45°C. What impressed me most was the quality of the welding—our inspection team did radiography testing on random seams, and all passed with flying colors. The supplier kept us updated throughout fabrication with photos and progress reports, which built a lot of trust. We've had zero leaks or performance issues since startup. Definitely planning to order another unit for our expansion project next year.

The welding quality was excellent—clean and uniform. We also appreciated that the supplier provided both English and Bahasa Malaysia nameplates, which helped with our local inspectors.

We've been sourcing pressure vessels for 30 years, and this unit's ASME U-stamp certification gave us confidence from day one. The SA516 GR.70 material traceability documentation was impeccable—full MTRs, NDE reports, and third-party inspection by TÜV. Delivery to Houston was 3 weeks ahead of schedule. The 200kL capacity fits perfectly into our hydrocracker expansion project. Weld quality exceeded API 510 standards. Definitely adding this manufacturer to our approved vendor list.
