Haihao Group Completes Export of NACE-Certified Inconel 825 Pipe Elbows to Turkish Energy Sector

Haihao Group, a leading international supplier of industrial piping systems, has announced the successful delivery of specialized Inconel 825 butt-weld pipe elbows to a major Turkish energy infrastructure project. The order, featuring both 90° and 45° long-radius configurations, highlights Haihao’s capacity to meet stringent requirements for corrosion-resistant pipeline components in aggressive environments.

Engineered for Sour Gas Resistance: Key Specifications

The shipment includes elbows manufactured from Nickel Alloy Inconel 825 (UNS N08825), a material selected for its superior performance in sour service applications. Compliant with ASME B16.9 (design standards) and ASME B36.10M (dimensional tolerances), these seamless fittings are designed to withstand high-pressure, high-temperature conditions common in oil refining, petrochemical processing, and offshore drilling.

ASME B16.9 Inconel 825 45 degree and 90 degree Pipe Elbows

Technical Highlights:

• Angle Options: 90° and 45° long-radius elbows
• Nominal Diameter: 150 mm (6 inches)
• Wall Thickness: 3.40 mm
• Schedule Rating: S-10S
• Material Grade: ASTM B366 WPNICMCUNS N08825
• Certification: EN 10204:2004 Type 3.1

Produced through a seamless manufacturing process, the elbows eliminate weld-related vulnerabilities, ensuring reliability in critical systems. Their compliance with NACE MR 01-75 further certifies their suitability for pipelines exposed to hydrogen sulfide (H₂S) and other corrosive substances.

Why Inconel 825? The Material Advantage

Inconel 825’s unique alloy composition—combining nickel, chromium, molybdenum, and copper—provides exceptional resistance to:

• Chloride stress corrosion cracking
• Pitting and crevice corrosion
• Oxidation at elevated temperatures

These properties make it indispensable for industries such as:

• Oil and gas exploration
• Chemical processing plants
• Desalination systems
• Power generation facilities

By opting for Inconel 825 pipe elbows, clients ensure long-term durability, minimized downtime, and compliance with global safety standards.
