The problem of thermal tightening for small floating heads in heat exchanger maintenance
Thread Content
Is it necessary to perform heat tightening on the small floating head of the heat exchanger during maintenance?
For the repair of heat exchangers, small floating heads usually require heating and tightening to ensure a tight connection and prevent leaks. .
How tight? Will it be tight again after opening it and letting the medium flow out?:lol
According to the bolt torque, heat tightening is not required. Factors such as bolt material, gasket type and material, and installation methods that affect the uniformity of bolt loads are responsible; most leaks occur due to uneven initial loading of the bolts. The issue that still needs to be addressed in hot tightening is the uniform distribution of bolt loads, a problem that can be resolved simultaneously in the cold state
