Typical Applications

Where alloy boiler tube is specified

Power and boiler systemsSuperheaters, reheaters, economizers, water wall related packages and boiler pressure parts where creep strength and heat treatment control are critical.
High-temperature pipeworkSteam lines, headers, high-temperature process pipe and auxiliary equipment where A335 / SA335 P grades may be specified.
Industrial pressure equipmentRefinery, petrochemical, utility and process packages requiring alloy grade traceability, NDE records and controlled delivery documentation.
Grade routing note

For boiler tubes, T grades such as T11, T22, T91 and T92 are normally routed against A213 / SA213. For high-temperature pipe packages, P grades such as P11, P22 and P91 are normally routed against A335 / SA335.

Inspection note

Alloy boiler tube quotation should define heat treatment, NDE, PMI, hardness, hydrotest, MTC level and any third-party inspection early, because these items affect mill selection and delivery lead time.

Buyer FAQ

Questions to settle before quotation

Which standards are common for alloy boiler tube?

Common references include ASTM A213 or ASME SA213 for seamless ferritic and austenitic alloy boiler, superheater and heat exchanger tubes, ASTM A335 or ASME SA335 for high-temperature seamless alloy pipe, and EN, JIS, DIN or GB project references.

What is the difference between T grades and P grades?

T grades such as T11, T22, T91 and T92 are commonly used for boiler and heat exchanger tubes under A213 or SA213. P grades such as P11, P22 and P91 are commonly used for high-temperature seamless alloy pipe under A335 or SA335.

Why is heat treatment important?

Alloy boiler tubes rely on the correct heat treatment condition for strength, hardness and high-temperature performance. The mill route should match the ordered standard, grade and project inspection plan.

What information is needed before quotation?

Confirm standard, grade, OD, wall thickness, schedule or drawing, length, heat treatment, inspection plan, PMI or NDE requirements, MTC level, packing, quantity and destination port.
