Stainless Steel Tube Bundles 316L Heat Exchanger Great heat transfer performance
What is tube bundle?
In a shell-and tube-exchanger the tube bundle is enclosed in a cylindrical shell, through which the second fluid flows.
A tube bundle is a set of tubes in a shell-and-tube heat exchanger.The tube plate at both ends of the tube bundle and the shell into one, simple structure, but only for hot and cold fluid temperature difference is not large, and the shell process does not require mechanical cleaning when the heat transfer operation. When the temperature difference is slightly larger and the shell pressure is not too high, can be installed in the shell with elastic compensation ring to reduce thermal stress.
