산업용 공기 냉각 열 교환기 (핀 팬 냉각기) ASME 코드 사용자 지정 제조 및 강제 드래프트 / 유도 드래프트 디자인

The normalized state of these flanges is highly uniform. We found no grain issues during subsequent NDT testing, and they fit the shell perfectly.

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.

This heater cut our fuel costs by 19% annually, meets API standards, and handles monsoon-season dust without issues. The Chinese vendor’s low price and easy installation saved us $12K upfront—ideal for Bangladesh’s growing oil sector.
