Industries & Applications
Projects in oil and gas, chemicals, power, and marine depend on tight material-to-media matches. Correct selection extends equipment life, stabilizes uptime, and reduces maintenance budgets. Typical applications range from process piping and exchangers to condensers, firewater lines, and structural elements.
- Oil & Gas, Petrochemicals, Refineries: Process piping, heat exchangers, columns, furnace coils, desalination modules and seawater intake systems.
- Chemical Processing & Fertilizers: Reactors, absorbers, pickling lines and acid service equipment using stainless, duplex, nickel alloys and reactive metals.
- Power & Desalination: Boilers, superheaters, condensers and cooling water systems requiring elevated-temperature and chloride resistance.
- Marine & Infrastructure: Cu-Ni and duplex for seawater; Corten for weather-exposed structures and facades.

Which Material Is Right for You?
Choosing the right material is critical. Use the pointers below to match your duty conditions to the best option, shortlist 1–2 grades, and confirm with tests and documentation.
- Start with the duty data: Note the fluid and contaminants, chloride ppm, pH, H₂S or CO₂, and dissolved oxygen. Record normal and peak temperature and pressure, plus any thermal or pressure cycling.
- Seawater and chlorides: Begin with Duplex 2205 for balanced cost and strength. Move to Super Duplex 2507 or 254 SMO as temperature and Cl⁻ rise; choose Titanium Grade 2 for the most robust, low-maintenance service.
- Cooling water, condensers, intake/outfall: Cu-Ni 90/10 or 70/30 offers seawater resistance with good heat transfer. Consider Duplex 2205 for higher strength, or Titanium where fouling, velocity, or temperature push limits.
- Warm brines and desalination: 254 SMO or Super Duplex 2507 handle high chlorides and crevice risk. Step up to Titanium if temperature or stagnation periods are expected during cleaning or outages.
- Mixed acids and shifting redox: Use Hastelloy grades where pitting, crevice attack, and SCC are concerns. For very strong acids at temperature, evaluate Tantalum; for chloride-rich acids, 254 SMO may be a cost-savvy bridge.
- High temperature and hot gas exposure: Inconel (600/601/625) provides hot strength with oxidation and carburization resistance. Incoloy 800/800H/825 suits long exposures in heaters and reformers where hot, corrosive media are present.
- General utility and large volumes: Carbon Steel is the value choice for moderate media and structural work. Shift to Alloy Steel for strength at temperature, or 304L/316L when hygiene or basic corrosion resistance is needed.
- Atmospheric exposure and architecture: Corten forms a stable patina in suitable atmospheres, reducing repaint cycles. Use where visual character and lower maintenance over life are priorities.
- Weight-sensitive equipment: Titanium Grade 2 or Grade 5 gives high strength-to-weight with chloride resistance. Useful for offshore hardware, condensers, and heat exchangers where mass matters.
- Sour hydrocarbons and H₂S service: Select Duplex or Super Duplex, or nickel alloys qualified to relevant sour-service standards. Control hardness and verify limits for Cl⁻, H₂S, and temperature before welding.
- Velocity, erosion, and solids: Check allowable flow rates, especially for Cu-Ni and stainless in sand-laden streams. Smooth layouts and generous radii at elbows reduce impingement and wall loss.
- Welding and fabrication checks: Match filler metals to base alloy, control interpass temperatures, and clean welds properly. Confirm U-bends, forming steps, and heat treatment align with project QA.
- Crevices and galvanic couples: Minimize gasket gaps and stagnant zones to limit crevice attack. Use isolation kits when dissimilar metals meet, for example Cu-Ni to steel or Titanium to stainless.
- Cleaning and shutdown chemistry: Pick materials that tolerate your CIP acids or alkalis and the oxygen content during idle periods. Validate that off-cycle chemicals will not trigger localized attack.
- Cost vs performance ladder: Typical progression: Carbon Steel, Stainless 300-series, Duplex, 6-Mo, Nickel Alloys, then reactive metals like Titanium or Tantalum. Compare life-cycle cost, not just material price.
- Compliance and documentation: Map selections to code requirements and test plans. Specify EN 10204 MTCs, NDT, PMI, IGC where applicable, and confirm corrosion allowance and thickness against design life.
What to send us: fluid and contaminants, chloride ppm, temperature and pressure range, velocity or solids, design code, and QA needs. We will shortlist compliant grades, propose testing, and quote with export-ready packing and timelines.
Frequently Asked Questions
1. What’s the practical difference between Duplex and Super Duplex stainless?
Both resist chloride attack better than 300-series stainless. Super Duplex has higher pitting resistance and strength, so it’s favored for severe seawater and subsea jobs. Duplex is often chosen where conditions are demanding but not extreme.
2. When should I consider SMO 254 instead of 316L or duplex?
Use SMO 254 when chloride levels and temperatures push 316L past its limits and when duplex is constrained by weldability or qualification. It’s a proven option in brines, desalination and chloride-rich chemistries.
3. Inconel vs Incoloy: which suits high-temperature duty?
Both work at elevated temperatures. Inconel grades like 625 are known for hot strength and oxidation resistance in furnaces and hot sections, while Incoloy 800/800H/825 combine high-temp stability with corrosion resistance in heaters and process equipment. Your media and temperature profile decide the choice.
4. Where are Copper-Nickel alloys used?
Cu-Ni 90/10 and 70/30 shine in seawater service such as condensers, desalination and marine cooling where biofouling and corrosion resistance reduce downtime.
5. Why pick a reactive metal like Titanium or Tantalum?
Choose Titanium when you need a strong, lightweight metal with excellent seawater and many chemical resistances. Choose Tantalum for very aggressive acids and mixed media where even high-nickel alloys struggle, especially in heat exchangers and reactors.
