Heat exchange tube spacing
Thread Content
For GB151 shell-and-tube heat exchangers, it is specified that the spacing between the heat exchange tubes should not be less than 1.25 times the tube diameter; furthermore, it is noted that for tubes with an outer diameter of 25 mm, the center-to-center distance should be 32 mm. Diameter 25, center distance 32 ； In this case, the gap between the pipes is only 7 mm. Is it convenient to carry out welding manually using an TIG welder? For regular heat exchangers, should a larger multiple be used or a specialized welding machine?
It can be welded, whether using manual TIG welding or a tube-sheet welding machine; what’s crucial is the length of the tube end protruding from the tube sheet, as this determines whether the welding will be successful or not.

How much should the pipe tip generally extend?
