ASTM A672 C70 pipe is a widely used electric fusion welded (EFW) carbon steel pipe for high-temperature and high-pressure applications. It is manufactured using high-grade raw materials and advanced welding techniques to ensure high mechanical strength, durability, and resistance to corrosion. It can be extensively used in oil and gas, power generation, petrochemical, and refinery industries, which demand high performance.
Table of Content
ASTM A672 C70 pipe is a heat-treated low-carbon steel pipe that has been made by electric fusion welding to give it added strength. It meets the standards of ASTM for use in high-pressure applications at moderate temperature. It possesses toughness, weldability, and resistance to thermal stress, making it suitable in harsh environments.
Manufactured with a minimum tensile strength of 450 MPa and a minimum yield strength of 240 MPa, these pipes offer high structural stability and reliability for applications in a variety of different industries.
It can be widely applied in oil and gas, power plant, boiler, and marine industries due to high performance.
Preferred in mechanical applications for use in machinery components and industrial pipe systems.
