51 alloy pipe network recommended: P91 alloy pipe use 1, P91 alloy pipe is widely used. The general-purpose P91 alloy pipe is rolled by common carbon structural steel, low alloy structural steel or alloy structural steel, and has the largest output, and is mainly used as a pipe or structural part for conveying fluid.
2, according to the use of different types of three types of supply: a, according to chemical composition and mechanical properties of the supply; b, according to the mechanical performance of the supply; c, according to the water pressure test supply. Pipes supplied by Types a and b, if used to withstand liquid pressure, are also subject to hydrostatic testing.
3. P91 imported alloy pipes for special purposes include P91 alloy pipes for boilers, P91 alloy pipes for geological use, and seamless pipes for petroleum.
