ASTM A213 Seamless Ferritic and Austenitic Alloy-Steel Boiler, Superheater, and Heat-Exchanger Tubes: T91: ASTM A335 Seamless Ferritic Alloy-Steel Pipe for High-Temperature Service: P91: JIS G3462 Alloy steel tubes for boiler and heat exchanger: STBA 26: GB 5310 Seamless steel tubes and pipes for high pressure boiler: 10Cr9Mo1VNbN (10Cr9Mo1VNb)
SA213 T91 Tube is a specification of ferritic and martensitic stainless steel and there are different grades. The T91 is one of the higher grades. It is applicable in high temperature applications. Hi-tech Metal & Tubes is a manufacturer and supplier of these pipes in various grades and types. The T91 Boiler Tube can vary in size from 3/8 inches to 30 inches in diameter and the length of the pipe could be
Whats the difference between T91 and P91 pipe? | SHEW-E STEEL
SA213 T91 Boiler Tube. SA213 T91 Material. T91 Alloy Steel Tube(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.
Growing experience with P91/T91 forcing essential code changes. By Jeffrey F Henry, Alstom Power Inc and ASME Task Group With todays combined-cycle powerplants operating at more demanding steam conditions and in more rigorous cycling duty than facilities built only a few years ago, designers increasingly are specifying creep-strengthenhanced ferritic steels-such as the modified 9Cr- 1Mo
T91 tubing belong to ASTM A213 which do Ferrite and Austenitic boiler superheater and heat exchanger seamless steel tube. But for ASTM A335 P91 tubing, they intended for Ferritic and alloy seamless steel tubes intended for high-temperature service.

Jun 04, 2018 · First of all, They are attributed to different standard categories. T91 tubing belong to ASTM A213 which do Ferrite and Austenitic boiler superheater and heat exchanger seamless steel tube. But for ASTM A335 P91 tubing, they intended for Ferritic and alloy seamless steel tube
The T91/ P91 steel is primarily used for superheater and reheater in power plant boiler construction, headers, main steam pipeline, as well as the heating furnace piping in petrochemical industry. Compared to other austenitic alloy steels, it has better thermal
