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.
