GH4169 High-Temperature Alloy Seamless Tubes for Oil and Gas Use description

GNEE GH4169 High-Temperature Alloy Seamless Tubes for Oil and Gas Use
GH4169 (also known as Inconel 718) seamless tubing is a high-temperature alloy highly favored in the oil and gas industry due to its high strength, corrosion resistance, and oxidation resistance even at temperatures up to 700°C (1300°F). Its durability under harsh conditions, excellent weldability, and superior mechanical properties (including high yield strength and tensile strength) make it ideal for demanding applications such as well casing, tubing, and drilling equipment.
GH4169 seamless steel pipe offers excellent high-temperature strength, corrosion resistance, and weldability, making it ideal for the aerospace, oil and gas, and power generation industries. Manufactured according to ASTM B983 and AMS 5589/5590 standards, this nickel-based alloy steel pipe boasts superior mechanical properties, including tensile strength up to 1380 MPa and excellent creep resistance. It maintains excellent oxidation resistance at temperatures up to 980°C (1800°F), ensuring durability in extreme environments. Our GH4169 seamless steel pipe can be customized in size and finish to meet customer requirements and is designed for critical applications.
