Import Heat Exchanger Tubes — Buy in Bulk from Supplier in China

The listing offers seamless heat exchanger tubes that meet a broad selection of international standards such as ASTM A213, ASTM A269, EN 10216‑5, DIN 17456 and GOST 9940. Materials include a full series of stainless steels like TP304/304L, 316/316L, 321/321H, 347/347H and nickel alloys such as 904L. Nominal diameters are supplied from ½ inch up to 32 inch NB and the outer‑diameter range runs from ¼ inch (6.25 mm) to 8 inch (203 mm). Wall‑thicknesses are available between 0.02 inch (0.5 mm) and 0.5 inch (12 mm) according to schedule numbers 5S, 10S, 40S, 80S and up to XXS.

The tubes are produced by cold‑drawn, cold‑rolled or precision‑rolled processes to achieve tight dimensional tolerances.
