A691 1-1/4CR Alloy Steel EFW Pipe
A691 1-1/4CR alloy steel EFW (Electric Fusion Welding) pipe is an alloy steel pipe manufactured using the electrofusion welding (EFW) process. The alloy composition of this steel pipe contains a higher proportion of chromium (Cr), specifically 1-1/4% chromium, so it is called 1-1/4CR.
A691 1-1/4CR alloy steel pipe is suitable for a variety of environments, especially in the petroleum, natural gas, chemical, electric power and other industries, for transporting fluid media such as steam, water, oil, gas, etc.
