ASTM A213 T11 hot-worked seamless pipes shall be manufactured by hot-rolled seamless process. Available in full annealing or isothermal annealing; or normalized and tempered for both heat treatment conditions. The maximum service temperature of ASTM A213 T11 grade alloy pipe is 560°C. It is a high temperature steel pipe with good oxidation resistance.
They are tested by non-destructive electrical or hydrostatic test and tempered at a temperature above 650°C to ensure that ASTM A213 T11 seamless boiler tubes are suitable for boilers, superheaters and heat exchangers.
ASME SA213 T11 alloy steel seamless pipes have good high temperature resistant physical properties and are used in various application industries such as petroleum, chemical, power, natural gas, water, metallurgy, shipbuilding, construction, etc.
