TEMA/ASME ヘアピン熱交換器 複数管型・二重管型 単通用Uバンドル 材料:CS / 304 / 316L / Ti / デュプレックス 設計温度-40°Cから500°C

We integrated this into our natural gas processing line. The fixed tube design is very compact and fits our layout perfectly. You can tell the materials are heavy-duty—it handles high pressure without a sweat.

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 SA516 Gr485 material is known for its low-temperature toughness, and the vendor confirmed the impact testing met our specifications. Shipping to a remote location is always challenging, but the crating was heavy-duty and protected the unit during the long truck haul.
