Inconel 625 seamless pipe SCH40 for offshore sour water treatment systems with excellent resistance to corrosion and H2S.

Looking for a trusted supplier? Want a quick reply ? Contact us for free advice.

We supply high-performance ASTM B444 Inconel 625 seamless pipe SCH40, specifically designed for offshore sour water treatment systems where corrosion resistance is critical.

Sour water systems in oil & gas operations contain hydrogen sulfide (H2S), chlorides, and other aggressive substances that can rapidly degrade conventional materials. Pipelines used in these environments must withstand both chemical corrosion and pressure variations to ensure safe and continuous operation.

Inconel 625 is a nickel-based alloy known for its excellent resistance to sulfide stress cracking, pitting, and chloride-induced corrosion. It performs reliably in harsh offshore environments, making it an ideal choice for sour service applications.

Our seamless pipes are manufactured with strict quality control to ensure uniform structure, high mechanical strength, and long-term durability, meeting international standards for oilfield applications.

Key Advantages

  • Excellent resistance to H2S corrosion and sour environments
  • Strong performance in chloride-rich offshore conditions
  • High strength under pressure fluctuations
  • Reduced risk of leakage and system failure
  • Long service life with minimal maintenance

Technical Specifications

  • Material: Inconel 625
  • Standard: ASTM B444
  • Type: Seamless Pipe
  • Schedule: SCH40
  • Length: 6 meters

Typical Applications

  • Sour water treatment systems
  • Offshore oilfield pipelines
  • Refinery processing units
  • Chemical handling systems

Using Inconel 625 pipes helps operators ensure safe operation, reduce corrosion-related failures, and extend system lifespan in sour service environments.
