ASME SA213 T5 Tubes

ASTM A213 (ASME SA213) T5 tube is a type of chromium-molybdenum alloy steel pipe. It contains 4.00% – 6.00% Cr and 0.45% – 0.65% Mo. Its UNS name is K41545. It is manufactured in accordance with the standard ASME SA 213/213M “Specification for Ferritic and Austenitic Alloy – Steel Seamless Tubes for Boilers, Superheaters, and Heat Exchangers”. It has has good high-temperature strength, oxidation resistance and corrosion resistance. Therefore, it is often used as seamless steel pipes for boilers, superheaters and heat exchangers.

We manufacture seamless steel pipes with outer diameters ranging from Ф6 to Ф114 mm and wall thicknesses from 0.8 to 10 mm. Our main materials include high-quality carbon steel, alloy steel, low-temperature steel, and corrosion-resistant steel, etc. We strictly control quality at every production stage to ensure all products are thoroughly inspected before delivery. We are certified with TS-A1, ISO9001, ISO14001, OHSAS18001, and pressure equipment licenses recognized in the EU, Germany, and Russia. Feel free to contact us for more information.

ASME SA213 T5 Tubes Standard Scope

This specification covers ferritic and austenitic seamless steel pipes used in boilers, superheaters, and heat exchangers. The steel grades include T5, TP304, etc. The pipe sizes range from an inner diameter of 1/8 inch (3.2 mm) to an outer diameter of 5 inches (127 mm), and the wall thickness ranges from 0.015 inch to 0.500 inch (0.4 mm to 12.7 mm). Other specifications can be provided according to order requirements. This standard is developed in both the International System of Units and the Imperial units, and it is required to be used independently. It also follows the standardization principles of the Technical Barriers to Trade (TBT) Committee of the World Trade Organization.
