How to Read P&ID

How to Read P&ID

Sound knowledge in P&ID is inevitable. The P&ID is the key input for all the piping activities. It is very important for a piping design engineers to read, understand and interpret the P&ID (Process design) in to mechanical system. Preparation of P&ID is the role of process engineer hence piping design engineer are only expected to understand P&ID. There is ... Read More »

History of Ultrasonics

History of Ultrasonics

Prior to world war II, sonar, the technique of sending sound waves through water and observing the returning echoes to characterize submerged objects, inspired early ultrasound investigators to explore ways to apply the concept to medical diagnosis. In 1929 and 1935, Sokolov studied the use of ultrasonic waves in detecting metal objects. Mulhauser, in 1931, obtained a patent for using ... Read More »

Pipe Routing Concepts

Pipe Routing Concepts

Piping engineering is not as simple as it sounds to be, so do pipe routing. Certain rules and logics to be considered for routing pipes in process plant or in other wise we can say industriall piping is different from other commerical piping system. Here is the list of parameters to meet the minimum design requirement. Simple routing Minimize fitting ... Read More »

P&ID and PFD

PID and PFD

Two of the most important drawing documents in this stage are… A Process Flow Diagram (PFD), shows all equipment in the process scheme like pumps, compressors, heater, reactors, distillation column that are required for processing, and links them up in the form of a flow diagram showing materials flow and heat flow through each of the equipment. The other most ... Read More »

Design Pressure Selection

Design Pressure Selection

Process design has requested that a vessel be designed to accommodate a new process. The vessel must be a jacketed vessel. The process is stable and the normal operating pressure of the inner vessel is 425 psi and the normal operating pressure of the jacket is 500 psi. During startup, the inner vessel must be pressurized to 350 psi before ... Read More »
