Explore our leading selection of engineered heat exchanger tubing configurations, designed specifically to meet the high mechanical load requirements and salinity exposures of projects in West Java and the Greater Jakarta Area.
As the economic heart of Indonesia, Jakarta and its surrounding industrial corridors (Cikarang, Karawang, and Cilegon) serve as vital processing hubs. The region's dense distribution of petrochemical plants, power generation complexes, and heavy marine ports creates an intense operational environment. Because of Jakarta's tropical coastal positioning, industrial heat exchange systems are subjected to highly saline sea cooling waters, humid atmospheres, and elevated ambient working temperatures.
Traditional austenitic steels like Grade 304 or even 316L frequently fail in these conditions due to chloride-induced stress corrosion cracking (SCC) and localized pitting. Consequently, engineering firms and procurement offices across Jakarta are shifting to Duplex 2205 (UNS S31803 / S32205) stainless steel heat exchanger pipes. Combining high mechanical yield strength with outstanding chloride resistance, Duplex 2205 reduces downtime, minimizes maintenance expenditures, and guarantees stable thermodynamic performance in critical cooling loops.
Duplex 2205 (UNS S31803 and UNS S32205) is characterized by a balanced 50:50 austenitic-ferritic microstructure. This dual-phase structure offers the best features of both classes: the corrosion resistance and weldability of austenitic grades, alongside the high mechanical properties and stress corrosion cracking immunity of ferritic grades.
| Alloy Grade | UNS Number | Cr (%) | Ni (%) | Mo (%) | N (%) | PREN Value | Yield Strength (MPa) |
|---|---|---|---|---|---|---|---|
| Duplex 2205 | UNS S31803 / S32205 | 22.0 - 23.0 | 4.5 - 6.5 | 3.0 - 3.5 | 0.14 - 0.20 | 34 - 36 | ≥ 450 |
| Austenitic 316L | UNS S31603 | 16.0 - 18.0 | 10.0 - 14.0 | 2.0 - 3.0 | - | 23 - 25 | ≥ 220 |
| Super Duplex 2507 | UNS S32750 | 24.0 - 26.0 | 6.0 - 8.0 | 3.0 - 5.0 | 0.24 - 0.32 | ≥ 40 | ≥ 550 |
The formula PREN = Cr + 3.3Mo + 16N shows the relative pitting resistance of stainless steels in chloride-containing media. With a PREN score consistently above 34, Duplex 2205 provides a cost-effective, high-reliability safety margin against localized pitting, outperforming conventional 316L in harsh environments like brackish cooling waters.
Indonesia's industrial sectors utilize Duplex 2205 heat exchanger and condenser tubing for several key configurations:
Resists volcanic H2S gases, carbon dioxide, and high chloride brines found in geothermal wells across West Java (Salak, Kamojang, Wayang Windu).
Used in umbilical piping, topside seawater cooling equipment, and deepwater instrumentation loops in the West Madura and Java Sea concessions.
Maintains critical heat exchange duties handling organic acids, chlorinated compounds, and high-pressure chemical processes.
The market price of Duplex 2205 heat exchanger pipes in Jakarta fluctuates based on global raw material costs (LME Nickel and Molybdenum prices), shipping freights, and local import tariffs. Custom processing steps like bright annealing, polishing, and customized coil shapes can also impact final pricing.
