UNS N07718 Nickel Alloy Seamless Pipe – API 6A Inconel 718 Tubes Manufacturer

UNS N07718 Nickel Alloy Seamless Pipe – API 6A Inconel 718 Tubes Manufacturer

The API 6A / UNS N07718 Nickel Alloy Seamless Pipe is manufactured from high-performance Nickel Alloy 718 (Inconel 718), a precipitation-hardened nickel-chromium alloy widely recognized for its outstanding strength, corrosion resistance, and fatigue resistance. Designed to meet API 6A requirements, these seamless pipes ensure reliable performance in high-pressure, sour service, and extreme offshore environments.

Key Features

• API 6A Certified – Complies with international standards for oilfield equipment and critical service environments.

• High Mechanical Strength – Retains superior tensile and yield strength up to 700°C (1290°F).

• Corrosion Resistance – Excellent resistance against sulfide stress cracking, chloride-induced corrosion, and sour gas.

• Seamless Construction – Provides defect-free internal structure with uniform wall thickness and higher pressure resistance.

• Extended Service Life – Withstands cyclic loading, extreme pressure, and aggressive media without degradation.
