P265GH P91 Alloy Steel Seamless Pipes Balck Seamless Carbon Steel Pipe

Name : X10CrMoVNb9-1 Alloy Steel Seamless pipes for High-temperature Service T91/P91 (X10CrMoVNb9-1)​

Definition :

Grade T/P91 is a ferritic-martensitic (9 % chromium, 1 % molybdenum) steel micro-alloyed with vanadium and niobium, and has a controlled nitrogen content according to ASTM A 335, A 213 or to EN 10216-2 standard under the designation X10CrMoVNb9-1.

Application :

On fossil-fuelled power plants, this grade is mainly used for high-temperature applications in superheater and reheater tubes, headers and steam piping (main steam and hot reheat).

Challenges :

Grade T/P91 exhibits excellent elevated-temperature strength and creep behavior up to 580 °C - 600 °C. Its 9 % chromium content offers better corrosion and oxidation resistance than grade 22. In addition, the reduced weight of boiler and piping components resulting from the steel's superior performance compared with other standard steels allows higher resistance to thermal fatigue. Compared with austenitic steels, grade T/P91 has higher heat transfer and lower thermal expansion coefficients.

Materials in industry standard designations: STD, 40, XH, 60, 80, 100, 120, 140, 160, XXH
Special customer designated nominal and minimum wall thicknesses can also be furnished.
Non standard OD & ID are available.

Best Pipeline can offer pipe from turned and bored forgings in accordance with Specifications A/SA369 when client requirements for size, wall thickness, quantity or delivery cannot be met by material available under Specifications A/SA335.

A/SA369 material is manufactured in grades including FP11, FP22, FP5, FP9, FP91, and FP92 corresponding to the same grades listed above for A/SA335.
