Теплообменник типа «труба в трубе» из углеродистой стали, устойчивой к коррозии под напряжением (HIC) | Сертификация NACE TM0284 для работы во влажной среде с H₂S

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.

Delivery was smooth—the unit arrived at Jebel Ali port within the promised timeframe, and the packaging protected it from the dusty environment during transport. Installation was quick because all flange alignments were perfect.

Technical bid included HTRI thermal simulation with fouling factor 0.0002 m²·K/W for our naphtha hydrotreater. SA516 Gr485 + 1.25Cr-0.5Mo tube combination optimized for high-temperature hydrogen sulfide resistance. Delivery EXW Qingdao to CIF Ulsan was 22 days, door-to-door. Zero NCRs during FAT. Korean PM assigned spoke technical English fluently. Already approved for Phase 2 EPC.
