How to calculate the allowable pulling stress for the connection between the heat exchange tube and the tube sheet
Thread Content
The connection between the heat exchange tubes and the tube sheet is made using strong welding. Standards specify that this value should be 0.5 times the smaller of the allowable stress of the heat exchange tube material at the design temperature and the allowable stress of the tube sheet material. How is this allowable pull-out stress determined through testing? I would appreciate guidance from those with expertise in this area
