ASME Shell and Tube Heat Exchanger HIC Resistant NACE TM0284 for Wet H2S Service
Our factory specializes in the design and manufacturing of HIC-resistant carbon steel shell & tube heat exchangers, with state-of-the-art technology to ensure compliance with NACE TM0284 standards. We emphasize stringent quality control, using advanced testing methods to ensure resistance to hydrogen-induced cracking (HIC), making our exchangers ideal for wet H₂S environments in industries such as oil & gas, petrochemicals, and refineries.
Common Carbon Steel Grades and Components
| Component | Material Grade | Features |
|---|---|---|
| Shell | SA516 Gr. 70 (HIC Tested) | Excellent strength & crack resistance |
| Tubes | SA179 / SA210 (HIC Tested) | High thermal conductivity |
| Tube Sheets | SA516 Gr. 70 or SA350 LF2 | Resistance to sulfide stress cracking (SSC) |
| Baffles | Carbon Steel (CS) | Supports efficient heat transfer |
| Gaskets | Spiral-wound SS with Graphite | Seals under high-pressure conditions |
Advantages and Disadvantages of Carbon Steel Heat Exchangers
| Advantages | Disadvantages |
|---|---|
| Cost-effective compared to stainless steel | Limited resistance to high corrosion |
| High mechanical strength | Requires regular maintenance |
| Suitable for wet H₂S and sour gas environments | Lower lifespan in highly acidic media |
| Easy to fabricate and repair | Can be heavier than alternative materials |
Common Types and Industry Applications
