Common use Material for Tube Bundle Heat Exchanger

There are two different tube bundles: Straight tubes and U tubes.

Depending on specific requirements and applications, there are the following tube material options:

Carbon Steel Tube : ASTM A179/ASME SA179/179M, ASTM A192, ASTM A333, ASTM A334

Alloy Steel Tubes: ASTM A213 T5, T9, T11, T22, T91

Copper Tubes

Applications:

Chemical Production

Petroleum Industry

Energy Power

Straight Tube Bundle VS U Tube Bundle

Straight tube bundle:

As the layout both ends in open status, the hot liquid is pumped through the bundle in a straight line from one end of the tank shell to another end of the tank shell. This type is efficient, but it requires more effort to open the tank shall remove the bundle to do cleaning or maintenance. Straight tube bundle has a lower installation cost than U tube bundle.

U Tube Bundle:

This bundle's impressive features are entry and exit points on the same side of the shell on a tube shell cap divided into two sealed chambers. The tubes are manufactured in U shape, which leaves the entry chamber and travels to the opposite end of the shell, and returns in the opposite direction to the exit chamber. This type of layout is easier to disassemble for maintenance with the bundle typically being slid out as a modular unit. U type tube bundle is also suited well with high temperature differences, relieves most thermal expansion and reduces contraction stresses in the bundle.
