Product Details

ASME SA213 T11 ALLOY STEEL SEAMLESS TUBE , BOILER AND HEAT EXCHANGE APPLICATION

A213 T11 is a specification for seamless ferritic and austenitic alloy steel boiler, superheater, and heat-exchanger tubes. It is commonly used in high-temperature applications such as power plants, refineries, and petrochemical plants. The A213 T11 alloy material exhibits good resistance to high-temperature oxidation and corrosion, making it suitable for environments with elevated temperatures and aggressive conditions. It is often used in the construction of boilers, superheaters, and heat exchangers where reliable performance at high temperatures is required.

Alloy steel tubes are a type of steel tubing that is made from alloyed steel, which is a combination of different elements such as chromium, molybdenum, nickel, or other alloying elements. These alloying elements are added to enhance the properties of the steel, such as increased strength, improved corrosion resistance, and better heat resistance.

Alloy steel tubes are commonly used in various industries, including oil and gas, power generation, automotive, aerospace, and construction. They are known for their high strength, durability, and ability to withstand high temperatures and pressures. These tubes are often used in applications that require resistance to corrosion, such as in boilers, heat exchangers, pipelines, and structural components.

The specific alloy composition and manufacturing process of alloy steel tubes can vary depending on the desired properties and intended application. They are typically produced through processes like seamless or welded manufacturing, and they come in various sizes, shapes, and grades to meet different industry requirements.

Main Materials of Alloy Steel:
ASTM A213 T5, T9, T11, T22, T23, T91, T92
ASTM A335 P5, P9, P11, P22, P91, P92

ASTM A/ASME SA 213 specification pipes are available in grades including T5, T9, T11, T22, T23, T91, T92. ASTM A/ASME SA335 Grade P5, P9, P11, P22, P91, P92. Alloy steel tubes are generally available in stock with OD sizes in all standard sizes and thicknesses.On demand, we can offer our customers with high quality alloy steel pipes and tubes with black painting, anti-corrosion oil and galvanised finish.
