Surface condensers are the most common type used in power plants. They are essentially shell-and-tube heat exchangers, in which the primary heat transfer mechanisms are the condensing of the saturated steam on the outside of the tubes and the forced convection heating of the circulating water inside the tubes.

Nearly all materials subject to cyclic loads break at stresses much lower than the rupture stresses produced by steady loads. The phenomenon is referred to as fatigue. Fatigue failures are defined as “repeated stress failures” and are results of stress repetition, rather than duration of time. Fatigue failure can also be a result of thermal variation; fatigue failure has occurred in boiler drums due to temperature variations in the shell at the feed water inlet. Read more

Seismic forces on a vessel result from a sudden erratic vibratory motion of the ground on which the vessel is supported and the vessel response to this motion. The principal factors in the damage to pressure vessels are the intensity and the duration of the earthquake motion. The forces and stresses in pressure vessels during an earthquake are transient, dynamic in nature, and complex. To simplify the design procedure, the vertical component of the earthquake is neglected, and the horizontal component is reduced to equivalent static forces. Read more

A skirt support consists of a cylindrical or conical shell welded to the bottom head of the vessel. A base ring at the bottom of the skirt transmits the load to the foundations through the anchor bolts. Read more

The User is responsible for defining all applicable loads and conditions acting on the pressure vessel that affect its design. These loads and conditions are specified in the User’s Design Specification. The manufacturer cannot include any loadings or conditions in the design that are not defined in the UDS. Read more

What is ASME Section VIII, Div. 2? ASME VIII-2 contains mandatory requirements, specific prohibitions, and non-mandatory guidance for the design, materials, fabrication, examination, inspection, testing and certification of pressure vessels and their associated pressure relief devices. This Code is also applicable to those chambers of combination units that are in the scope of ASME VIII-2. Read more

Tall pressure vessels are generally defined as those where the height to diameter ratio (H/D) is more than 15. These vessels are built these days as self-supporting structures, i.e., they are supported on cylindrical or conical skirts with a base ring resting on a concrete foundation and firmly fixed to the foundation by anchor bolts embedded in concrete.
