Product Description

Product Description

ASTM A213 T22 Seamless Ferritic Alloy-Steel Boiler Tubes are made by the seamless process,ASTM A213 T22 Steel Tubes for Seamless Ferritic and Austenitic Alloy-Steel Boiler, Superheater, and Heat-Exchanger Tubes.

T22 Boiler Tube is a high temperature tolerance tube that is used in acidic and corrosive environments such as the hydrochloric processing and in aluminum chloride catalyst involving applications. The material is resistant to strong inducing agents. Multi Metals (India) is a large supplier and manufacturer of the T22 Boiler Tube in various specifications, standards and types. There are seamless, EFW and Fabricated types with specification ASTM A213 and A691. The standards are according to ASTM, ASME and API standards. The outer dimensions of the tubes range from ½ inches to 5 inches but custom diameter tubes are also possible with us.

The T22 Tube Materials have low carbon less than 0.15%, manganese, phosphorus, sulfur, silicon and molybdenum in the composition. It has 163 HB max hardness, 205MPa minimum yield strength and 415MPa minimum tensile strength. The Sa213 T22 Tube can be welded with most conventional methods. Where the oxy-acetylene or submerged arc welding methods are to be employed, the tube has to be post weld heat treated; mostly annealing.

ASTM A213 T22 Steel

A213 T22: "A" is the mark of ASTM steel material. "213" refers to the code sequence number, "T22" refers to the steel grade classification, "t" refers to small diameter pipe, equivalent to 12CR2MOG small diameter pipe in China.)

 

A213 T22 is a chrome molybdenum high temperature ferritic steel for boiler and superheater with ASTM A-213 / A-213m standard steel grade of 2.25Cr-lMo. It was transplanted to GB5310 in 1985 and named 12CR2MOG. Other countries also have similar steel grades, such as 10CrMo910 in Federal Germany and stba24 in Japan. In the CR -1Mo steel series, its thermal strength performance comparison draft; at the same temperature (temperature ≤ 580 ºC), its creep fracture strength and allowable stress are even higher than that of 9Cr - 1Mo steel; moreover, it has good processability, weldability and durable plasticity. Therefore, it has been widely used in the harsh working environment, such as various heating pipes and high-pressure vessels in thermal power, nuclear power and some hydrogen generating equipment.

Surface Condition
Ferritic alloy cold-finished steel tubes are free of scale and suitable for inspection.
Ferritic alloy hot-finished steel tubes are free of loose scale and suitable for inspection.
 Note: Material furnished under ASTM A213 conform to the applicable requirements of the current edition of Specification A1016/A1016M

 

Application:

Allowable operating temperature: it is mainly used for superheater with wall temperature ≤ 580 ° C and steam pipe and header with wall temperature ≤ 540 ° C of large capacity power station boiler such as 300. 600MW. This kind of steel has been widely used in the United States, Japan and Europe. It has a long history in power plant operation and is a mature steel with stable running and good process performance.
