Product Description
ASTM A335 P5 P9 P11 P22 P91 Alloy Steel Pipe
Available in sizes from 1/2" to 80" for high-temperature industrial applications
Product Overview
X10CrMoVNb9-1 Alloy Steel Seamless Pipes for High-temperature Service T91/P91 (X10CrMoVNb9-1) are premium ferritic-martensitic steel pipes micro-alloyed with vanadium and niobium, manufactured according to ASTM A335, A213, and EN 10216-2 standards.
Primary Applications
These alloy steel pipes are specifically designed for fossil-fueled power plants, serving critical roles in:
- Superheater and reheater tubes
- Headers and steam piping systems
- Main steam and hot reheat lines
Performance Advantages
- Excellent elevated-temperature strength and creep resistance up to 580°C - 600°C
- Superior corrosion and oxidation resistance with 9% chromium content
- Enhanced thermal fatigue resistance through reduced component weight
- Higher heat transfer coefficients compared to austenitic steels
- Lower thermal expansion coefficients for improved stability
Available Specifications
Standard wall thickness designations: STD, 40, XH, 60, 80, 100, 120, 140, 160, XXH
Custom nominal and minimum wall thicknesses available upon request. Non-standard OD & ID dimensions can be furnished to meet specific project requirements.
Alternative Manufacturing Options
When size, wall thickness, quantity, or delivery requirements cannot be met by A/SA335 specifications, we offer pipes from turned and bored forgings in accordance with A/SA369 specifications. Available grades include FP11, FP22, FP5, FP9, FP91, and FP92.
