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
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.
