Alloy Steel Seamless Tube Heat Exchanger U Bend Tube ASTM A213 T5 T9 T11 T22 Boiler Tube Condenser Air Cooler

ASTM A213 T9 ALLOY STEEL SEAMLESS U BEND TUBE HEAT EXCHANGER TUBING


ASTM A213 T9 Seamless Ferritic and Austenitic Alloy-Steel Boiler, Superheater, Heat-Exchanger Tubes.

ASME SA213 T9 Tube is useful in modern power devices that operate with high efficiency to guarantee their long-term, e and trouble-free operation. ASTM a213 T9 Tube is used to heat water that is circulated through a closed loop piping system for general facility and service water heating. Low-temperature systems generally operate below 200°C. Medium-temperature systems generally operate between 200 and 250°C. SA213 T9 Boiler Tube is made from heat resisting carbon and low alloy steel which can withstand the loads at various pressures and temperatures. Boiler tubes is useful for parts of energy type equipment’s like boilers, super heaters, economizers, heat exchangers, etc. T9 boiler tubes are manufactured as hot rolled or cold drawn with welded and seamless manufacturing process.
ASTM A213 T9 Grades containing the letter H in their designation have requirements different from those of similar grades not containing the letter H. These different requirements provide higher creep-rupture strength than normally achievable in similar grades without these different requirements. ASTM A213 T9 tubes shall be made by the seamless process and shall be either hot finished or cold finished, as specified. Grade TP347HFG shall be cold finished. Heat treatment shall be done separately and in addition to heating for hot forming. The ferritic alloy and ferritic stainless steels shall be reheated. On the other hand, austenitic stainless steel tubes shall be furnished in the heat-treated condition. Alternatively, immediately after hot forming, while the temperature of the tubes is not less than the minimum solution temperature, tubes may be individually quenched in water or rapidly cooled by other means. Tension test, hardness test, flattening test, and flaring test shall be done to each tube. Also, each tube shall be subjected to the nondestructive electric test or hydrostatic test.

Overview of ASTM A213


A213 is often called chrome moly tube because of the chemical makeup of Molybdenum (Mo) and Chromium (Cr). Molybdenum increases the strength of steel as well as the elastic limit, resistance to wear, impact qualities, and hardenability. Moly increases the resistance to softening, restrains grain growth and makes chromium steel less susceptible to embrittlement. Moly is the most effective single additive that increases high temperature creep strength. It also enhances the corrosion resistance of steel, and inhibits pitting. Chromium (or chrome) is the essential constituent of stainless steel. Any steel with 12% or more Chrome is considered stainless. Chrome is virtually irreplaceable in resisting oxidation at elevated temperatures. Chrome raises the tensile, yield, and hardness at room temperatures. The composition chrome moly alloy steel Pipe make it ideal for use in power plants, refineries, petro chemical plants, and oil field services where fluids and gases are transported at extremely high temperatures and pressures.


Features of ASTM A213 T9 Alloy Steel Heat Exchanger Tubes


  • A213 T9 seamless alloy tubes shall be delivered in fully killed, and either as hot-finished or cold finished product..Heat treatment is carried out separately and in addition to hot forming.
  • Flattening Test - One flattening test shall be made on specimens from each end of one finished tube, not the one used for theflaring test, from each lot.
  • Faring Tiest - One flaring test shall be made on specimens from each end of one finished tube,not the one used for the flatteningtest, from each lot.
  • Hydrostatic or Nondestructive Electric Test - Each tube shall be subjected to the nondestructive electric test or the hydrostatic test.The type of test to be used shall be at the option of the manufacturer, unless otherwise specified in the purchase order.
