Super Duplex UNS S32750 Pipe For Oil & Gas
Super Duplex UNS S32750 Pipe for Oil & Gas
Chemical Composition:
Chromium (Cr): 24-26%
Nickel (Ni): 6-8%
Molybdenum (Mo): 3-5%
Nitrogen (N): 0.24-0.32%
Other elements: Includes low carbon, small amounts of manganese, silicon, copper, etc.
Key Benefits:
High Corrosion Resistance: UNS S32750 has superior resistance to pitting, crevice corrosion, and chloride-induced stress corrosion cracking, making it ideal for subsea and saline environments.
Mechanical Strength: It has approximately twice the yield strength of conventional austenitic stainless steels, allowing for the design of thinner and lighter pipes without compromising performance.
Thermal Stability: Excellent resistance to high temperatures and thermal cycling, ideal for high-pressure and high-temperature conditions common in oil and gas extraction.
Long Service Life: With its ability to withstand aggressive environments and mechanical stress, this alloy ensures lower maintenance and extended operational life.
Applications in Oil & Gas:
Subsea pipelines: Super Duplex UNS S32750 is commonly used in underwater pipelines due to its superior corrosion resistance in seawater.
Offshore platforms: Used for heat exchangers, flowlines, and processing systems exposed to saltwater and chemicals.
Chemical injection lines: Provides safe transport of chemicals to wellheads for enhanced oil recovery (EOR) operations.
Desalination plants: Used for corrosion-resistant piping in offshore oil facilities where seawater is used for cooling or processing.
Standards & Specifications:
ASTM A789/A790: Specifications for seamless and welded UNS S32750 pipes.
NACE MR0175/ISO 15156: Compatibility with sour (H₂S) gas environments.
Pressure Ratings: These pipes can handle high-pressure applications typical in oil and gas production environments.
Sizes & Availability:
Available in seamless or welded pipes.
Outer Diameter (OD) typically ranges from 0.5" to 48" depending on application.
Thickness varies as per project requirements (Schedule 10S, 40S, 80S, etc.).
This alloy is preferred when strength and corrosion resistance are crucial, ensuring reliability in the demanding conditions found in oil and gas extraction, especially offshore operations.
