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.
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.
In our São Paulo refinery, humidity and rain used to cause overheating. This hot oil heater solved it with 21% energy savings and API 560 compliance. It’s robust in tropical storms, and the Chinese supplier offered same-week technical support. Cost-effective for Brazil’s budget-conscious refineries!
