As per API RP 573...
1. Please describe the difference between Bowing and Sagging of tubes in Fired heaters and do the same acceptance limits apply for Bowed as well as sagged tubes.
In both sagging and bowing, tubes deformation is due to creep phenomenon as per API RP 573. So the acceptance limit of both sagged or...
