SA266 グレード2N 熱交換器用炭素鋼シェルフレンズ ASME規格

Fully meets the rigorous requirements of TEMA R standards. We used these SA266 Grade 2N flanges for a refinery project in Texas. The machining precision is impressive, and the sealing face finish is absolutely perfect.

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.

Typhoons often disrupted our operations in Manila. Since installing this API 560 heater, efficiency jumped to 94%, with zero failures during storms. It’s compact, API-certified, and the Chinese team provided typhoon-proof installation tips.
