Clapet ASME SA516 Gr.70 en acier

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 packaging was very solid; even after long-distance sea freight, there were no dents on the sealing faces.

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.
