Lord Fin Tube-ASTM A213 TP309 Seamless Tube

What is ASTM A213 TP309 seamless tube?

ASTM A213 is a standard specification for seamless ferritic and austenitic alloy-steel boiler, superheater, and heat-exchanger tubes. This specification covers grades of minimum wall thickness, seamless, and cold-drawn, intermediate alloy steel tubes for heat exchangers, condensers, and similar heat transfer apparatus. The TP309 is designed to have high-temperature strength, resistance to oxidation, and excellent heat resistance.

The chemical composition of ASTM A213 TP309 Seamless Tube is as follows:

Carbon (C): 0.08 max

Manganese (Mn): 2.00 max

Phosphorus (P): 0.045 max

Sulfur (S): 0.030 max

Silicon (Si): 0.75 max

Chromium (Cr): 22.0-24.0

Nickel (Ni): 12.0-15.0

The mechanical properties of ASTM A213 TP309 Seamless Tube are as follows:

Tensile Strength: 515 MPa (75,000 psi) minimum

Yield Strength: 205 MPa (30,000 psi) minimum

Elongation: 40% minimum

Hardness: Brinell 217 maximum, Rockwell B 95 maximum

ASTM A213 TP309 seamless tube usages:

The TP309 is designed to have high-temperature strength, resistance to oxidation, and excellent heat resistance.

The seamless tube produced according to this specification is suitable for use in high-temperature applications such as in petrochemical plants, power plants, and refineries, where elevated temperatures and high pressures are common.

The ASTM A213 TP309 seamless tube is available in a range of sizes and thicknesses, and can also be customized to meet specific requirements. It is manufactured using various techniques such as cold-drawing, hot-finished, and cold-finished methods.

It is important to note that this specification only covers the manufacturing of the tube and does not include any guidelines for the design or installation of the tube in a given application. It is recommended to consult with a qualified engineer or professional before selecting or using this product in any specific application.
