Piping systems are used to transport liquids and gases in many industrial applications like power plants, laboratories, and hospitals. They are made up of pipe sections joined with fittings and supported by hangers. Understanding piping fundamentals, materials, design, fabrication, installation, and testing is important for working in piping system design and construction. Basic engineering documents for piping include block flow diagrams, process flow diagrams, piping and instrumentation diagrams, piping layout drawings, isometric drawings, and equipment layouts. Common abbreviations used include designations for piping services and equipment as well as notes on insulation, pipe materials, joint types, and dimensions.

- 1. INTRODUCTION TO PIPING Pipe sections when joined with fittings, valves and other mechanical equipment and properly supported by hangers and supports are called PIPING.
- 2. The Piping systems are an essential and integral part of our modern civilization just as arteries & veins and are mainly used for transportation of liquid or gases. The piping systems in thermal power plants are used to convey high-pressure and high-temperature steam to generate electricity. Other piping systems in a power plant transport high-and low-pressure water, chemicals, low- pressure steam, and condensate.
- 3. Piping systems are used in hospitals to transport gases and fluids for medical purposes. The piping systems are used in laboratories carry gases, chemicals, vapors and other fluids that are critical for conducting research and development. If you have strong visualization power and if you are very keen in learning every day in your life then only there is a huge scope in Piping System Design, Construction of Piping, operation, maintenance of various piping systems including Inspection and Testing. To work in this field one need to understand the basic piping fundamentals, various materials used in projects & selection criteria, specific design considerations, fabrication & installation, testing & inspection requirements.
- 4. BASIC ENGINEERING • Block Flow Diagrams (BFD): Very simple diagrams composed of rectangles and lines indicating major material or energy flows. • Process Flow Diagrams (PFD's): Typically more complex diagrams of major unit operations as well as flow lines. They usually include a material balance, and sometimes an energy balance, showing typical or design flow rates, stream compositions, and stream and equipment pressures and temperatures.
- 5. • Piping and Instrumentation Diagrams (P&ID's): Diagrams showing each and every pipeline with piping class (carbon steel or stainless steel) and pipe size (diameter). They also show valving along with instrument locations and process control schemes. • Piping Layout (Orthographic- Plans and Elevations) Piping layout is developed in both plan view and elevation view and section details are added for clarity wherever necessary. These drawings are called the General Arrangement of Piping.
- 6. • Isometrics – (Pictorial - Isometric Views) In complex piping system, especially within the unit/plant building where orthographic views do not illustrate the details of design, pictorial view in isometric presentation is drawn for clarity.
- 7. Equipment Layout Equipment Layout is just that-where pieces of equipment, such as displays and controls, are laid out in relation to everything else around them. We also have to fix the co-ordinates (North East) of the Equipment in layout.
