GNEE offers precision engineered A691 91CR Alloy Steel EFW Pipes at cost-effective prices for various engineering applications.
A691 9CR grade alloy steel welded pipe contains a combination of copper, silicon, phosphorus, nickel and chromium content. A691 9CR welded steel pipe thus has excellent high temperature properties. It can withstand high temperatures up to about 600°C (1112°F) while maintaining its mechanical properties. But the pressure limit depends on the pipe size, wall thickness and specific design criteria.
A691 9CR alloy steel straight seam pipe is widely used in the oil and gas industry, chemical industry and power industry due to its high strength and creep resistance.
