Thane Office: 701, Yash Ashoka CHS,Kopri, Station Road, Thane(E)– 400 603 MH, India INTRODUCTION What is Static Equipment? “Static Equipment” is a term in Mechanical Engineering which refers to any equipment which is in static mode of motion or does not have any rotating part. Examples of Static Equipment include Pressure vessels, Heat exchangers, Columns, Stacks, Storage Tanks and Reactors. The use of Static Equipment is common in the Process Industry which includes Refineries, Power Plants, Chemical Plants & Fertilizer Plants. The focus of this one-day workshop is to study some of the important clauses & concepts of ASME SEC VIII Div. 1 applied to design Static Equipment (Pressure Vessel). This code is based on “Design by rule” which means it is based on equations & formulas. But before we go further, we should contrast Static Equipment with Rotating Equipment. As the name suggests Rotating Equipment has at least one rotating part. Some examples are Pumps, Blowers, Compressors and Agitators. Rotary equipment has a different set of design codes and will often have a proprietary design as it takes many years of design plus manufacturing and working experience to develop the product. So, in Rotary Equipment, the designer and the fabricator are usually the same company or person and they develop their product over a number of years and by taking feedback and making incremental improvements. In this workshop, we’ll stay focused on Static Equipment Design. PAGE NO. 3 ABHISHEK SINGH SCOOTOID ENGINEERING SOLUTIONS PVT LTD.
