ASME SA213 TP316L Seamless Tube for Heat Exchanger, Boiler & Superheater

ASME SA-213/SA-213M covers seamless ferritic and austenitic alloy-steel boiler, superheater, and heat-exchanger tubes. TP316L is UNS S31603, a low-carbon austenitic stainless steel. Typical furnished sizes are 1/2 in. [3.2 mm] inside diameter to 5 in. [127 mm] outside diameter, with 0.015 to 0.500 in. [0.4 to 12.7 mm] minimum or average wall thickness. Tubes may be hot finished or cold finished.

Per ASME SA-213/SA-213M Table 2.

Key control points: maintain solution treatment temperature, use rapid cooling to reduce carbide precipitation risk, and keep heat number and heat-treatment lot traceability. For TP316L, ASME SA-213/SA-213M Table 3 does not list an austenitic grain size requirement.

Yuhong can pair TP316L tubes with tube bundles, U-tubes, finned tubes, tubesheets, baffles, and heads. Within ASME SA-213/SA-213M, related austenitic grades include TP304/304L/304H, TP316/316L/316H, TP321/321H, TP347/347H, and others. For heat-exchanger projects, TP316L can be quoted as straight lengths, U-bends, pickled or bright annealed, with ends prepared as required.

ASME SA213 TP316L tube is used in heat exchangers, boilers, superheaters, condensers, air coolers, pressure vessels, petrochemical plants, power generation, and chemical processing. Its low carbon content and molybdenum addition support use in many corrosive and chloride-bearing service conditions where improved pitting and crevice corrosion resistance is needed.

TP316L has a lower carbon maximum, 0.035%, which helps reduce carbide precipitation during welding or elevated-temperature exposure.

Product analysis, tension, hardness, flattening, flaring, and per-tube hydrostatic or nondestructive electric testing, as required by ASME SA-213/SA-213M.
