Process Flow Diagram (PFD) – Piping and Instrument Diagram (PID)

Process Flow Diagram or Piping and instrument diagram For an engineer, the drawing is everything. An engineer must understand all drawing i.e Process Flow Diagram (PFD), Piping and Instrument Diagram (PID), Isometric drawing, engineering drawing, manufacture drawing, welding-map drawing or As-built drawing. Engineer who cannot read drawing can be considered as a blind engineer. Which drawing is the most important? Every drawing is important, depending on the purpose we use it. PFD-Process Flow Diagram is a helicopter view of a plant. From this drawing, we can see the production process in general, the stage of production and capacity in every[…]

Introduction to Pipeline Code ASME B31.4

The most popular pipeline code in the industry is ASME B31.4. Mechanical engineer is required to understand this code if he want to be hired by Oil and Gas Company. Basically ASME B31.4 specifies requirements for design, material selection, construction / assembly procedures, inspection / testing, and maintenance of liquid pipe systems between fields or production facilities, tank farms, above or underground storage facilities, processing plants natural gas, refineries, pumping stations, ammonia plants, terminals (marine, railway, and truck), and other delivery and receiving points, as well as fluid-carrying pipelines in pumping stations, tank farms and terminals associated with piping systems[…]

Entry level Mechanical Engineer must learn Process Piping code ASME B31.3

Some of mechanical engineering students  learns basic design of piping and pipeline in college. we must learn some piping and pipeline code in industry that we never get it in college. The most popular piping code is ASME B31.3 that used in process piping and ASME B31.1 for power piping. Process piping is a piping system installed inside a plant that used to connect equipment. This Code has the intent to be an engineering requirement in designing a safe piping system in both design and installation. But, one thing must be kept in mind, that the Code does not apply[…]
