Haihao Group Supports Turkish Energy Project with Advanced Inconel 825 Pipes
In the world of energy engineering, sour gas systems represent one of the harshest operating conditions. Corrosion, high pressure, and fluctuating temperatures can quickly erode materials that are not purpose-built for endurance.
When a leading Turkish EPC contractor sought high-performance piping for a sour gas project, they turned to Haihao Group—a long-established manufacturer known for its precision-engineered nickel alloy and carbon steel piping products.
Haihao supplied a batch of Inconel 825 seamless pipes, measuring 6 inches in diameter and Schedule 10S (3.4 mm wall thickness), in strict accordance with ASTM B423 UNS N08825 and ASME B36.19M.

Why Inconel 825? The Material Behind the Performance
The Inconel 825 alloy—a nickel-iron-chromium base enhanced with molybdenum, copper, and titanium-offers exceptional resistance to both oxidizing and reducing acids. This makes it particularly suited for hydrogen sulfide environments, which are common in sour gas production.
Its resilience against pitting, stress corrosion cracking, and intergranular attack ensures long-term operational safety, even under extreme chemical exposure.
“We don’t just supply pipes-we deliver confidence,” said a Haihao materials engineer. “Our Inconel 825 products are built for stability, tested for integrity, and certified for performance.”
From Design to Delivery: Every Detail Matters
Each Inconel 825 seamless pipe was produced using advanced cold-drawn forming to ensure uniform grain structure and dimensional accuracy. The beveled ends were prepared for on-site welding, and every unit was coated with protective oil to prevent oxidation during transit.
Haihao’s products were delivered with EN 10204 3.1 certification, ensuring full traceability from raw material to finished component. The pipes meet the NACE MR0175 requirement for sour service applications-an essential specification for safe energy transport systems.
A Long-Term Commitment to the Global Energy Market
This shipment marks another milestone in Haihao’s partnership with international clients who operate in oil & gas, refining, and petrochemical sectors. Over the years, the company has developed an extensive supply record covering nickel alloys (Inconel, Incoloy, Monel), duplex stainless steels, and high-temperature alloys.
By combining engineering expertise with custom fabrication capabilities, Haihao Group continues to deliver solutions tailored to the world’s toughest projects.
