ASME SA 213 / SA 213M covers seamless ferritic and austenitic alloy-steel boiler, superheater, and heat-exchanger tubes. For stainless steel tubing supply, the most common grades include TP304, TP304L, TP316, TP316L, TP321, TP347, and other heat- and corrosion-resistant grades.
These seamless tubes are widely used in boilers, condensers, heat exchangers, pressure vessels, power plants, petrochemical equipment, and other high-temperature or corrosive service conditions where reliable dimensional accuracy and material consistency are required.

These stainless steel seamless pipes and tubes are typically packed in seaworthy export packaging to ensure safe transportation and long-distance delivery.
Depending on the product size and customer requirements, the pipes or tubes are bundled with protective straps, packed in wooden cases, plywood cases, or hexagonal bundles, with both ends protected by plastic caps where applicable.
Each package is clearly labeled with grade, size, standard, heat number, and shipment details for full traceability. Waterproof wrapping, woven bags, and anti-rust protection can also be provided to ensure the materials arrive in good condition during ocean shipment and storage.

Answer: ASME SA 213 is mainly used for seamless boiler tubes, superheater tubes, and heat exchanger tubes in high-temperature and pressure service.
Answer: SA 213 is mainly for heat exchanger, boiler, and superheater tubing, while SA 312 covers stainless steel seamless and welded pipe for general corrosive and high-temperature service.
Answer: Yes. TP316L is one of the common grades supplied under ASME SA 213.
