Safe And Removable High-Efficiency Double Tube Sheet Heat Exchanger

Description

The double tube sheet heat exchanger is a heat exchanger with two tube sheets with a certain gap at one end of the heat exchanger or equivalent to two tube sheets with a certain gap. In actual operation, double tube sheet heat exchangers are generally used in the following two occasions: one is to absolutely prevent the mixing of the medium between the tube and shell sides, for example, for the shell-side water, the tube-side chlorine or chloride.

Comparison of Double Tube Sheet Heat Exchanger and Single Tube Sheet Heat Exchanger Manufacturing

① Different manufacturing costs: Compared with the single tube sheet heat exchanger, the double tube sheet heat exchanger has two outer tube sheets, a cavity between the two inner and outer tube sheets, and a heat exchange tube in the cavity.

② Different expansion joints: There are generally four types of connection between heat exchange tubes and tube sheets, namely strength welding (common argon arc welding), strength expansion, strength welding + sticking expansion, strength expansion + sealing welding, the difference is mainly reflected in Whether the pipe hole is slotted or not, the welding groove and the extension length of the pipe, etc. Expansion can be divided into non-uniform expansion (mechanical ball expansion), uniform expansion (hydraulic expansion, liquid bag expansion, rubber expansion, Explosion expansion, etc.).

The design of the double tube sheet heat exchanger requires strength welding + strength expansion, and the hydraulic tube expansion method is adopted.

The general design of single tube sheet heat exchanger requires strength welding + stick expansion, and mechanical expansion or manual expansion can be used.
