The scope of this presentation is to present basic information and understanding of the ASME code for the design of pressure vessels for the chemical and process industry as applicable in the United States and most of North and South America. Pressure vessels are manufactured all over the world under various international standards. These standards specify the requirements to be met during the manufacture of pressure vessels; however, the means used to meet the requirements are not specified in any of these standards. Read more

In this article, the topics are arranged according to the sequence of manufacture of a pressure vessel under the following assumptions: 1. The dished ends and cones are bought from outside with the material supplied by the vendor under proper certification. 2. All plates and piping materials, including but not limited to pipes, elbows, flanges, studs/ bolts and nuts, gaskets, etc., are bought out items from reputed vendors with proper certification.

Tubes are the basic components of shell and tube heat exchangers, providing the heat transfer surface between one fluid flowing inside the tube and the other fluid flowing across the outside of the tube. The tubes may be seamless or welded and most commonly made of copper or steel alloys. Other alloys of nickel, titanium, or aluminum may also be required for specific applications. Seamless tubing is produced in an extrusion process; welded tubing is produced by rolling a strip into a cylinder and welding the seam. Welded tubing is usually more economical. Read more

Arc welding is one of several fusion processes for joining metals. By the application of intense heat, metal at the joint between two parts is melted and caused to intermix – directly or, more commonly, with an intermediate molten filler metal. Upon cooling and solidification, a metallurgical bond results. Read more

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
