Heat exchanger tube

Tube, pipe, fittings and flanges

Heat exchanger tube in an extensive range of austenitic stainless steels, duplex stainless steels, nickel alloys, titanium and zirconium, suitable for all types of heat exchangers, such as seawater coolers, condensers, evaporators, heaters and reheaters.

Heat exchanger tube

Our heat exchanger tube portfolio includes imperial and metric sizes, from outside diameter 12 mm up to 40 mm (0.472 to 1.575 in.). Special sizes can be made to order. Alleima heat exchanger tubes are supplied in straight lengths up to 30 meters, or as U-bent tubes.

Lower life-cycle cost with duplex stainless steels

Our portfolio of duplex stainless steels is the widest on the market. Duplex stainless steel heat exchanger tubes perform exceptionally well in a variety of environments and media common in process industries, resulting in lower life-cycle costs.

An innovative and sustainable alternative to expensive nickel alloys

Choosing the right material can advance the life of your heat exchanger

Heat exchangers are crucial in process industries. These include refineries, petrochemical, and chemical plants. They heat and cool process streams. They conserve energy in the plant and minimize additional heat from external sources by burning gas or oil or using electricity. The most common industrial heat exchanger is the shell-and-tube type.
