What is piping isometric drawing?
Piping engineer world
by ellaya86
1y ago
Piping isometric drawings is the term used for automatically generating spool sheets, complete with bills of materials (BOM) for pipe spool fabrication which satisfies the process requirements. Isometrics are modelled and generated from 3D model software into 2D drawings (isometric sheet) which is used for fabrication by construction subcontractor. An isometric usually shows a complete line from one piece of line or equipment to another. It gives all information necessary for fabrication and erection of piping. Items and information to be shown on an isometrics include: North arrow (Plant nor ..read more

How to design pump piping ?
Piping engineer world
by ellaya86
2y ago
This chapter highlights the types of pumps commonly found in industrial plants, along with maintenance and operation considerations for a pump and operation considerations for a pump piping layout. The two primary piping connections are the suction and discharge nozzles (i.e. Liquid inlet and outlet).The impeller Within the pump case draws the liquid into the pump and sends it out at a high velocity. The impeller shaft is sealed with a stuffing box where the shaft exists the case to prevent the pump fluid from leaking, Drips from wearing seals are picked up in the stiffing box drain. The pump ..read more

What is Piping and instrumentation diagram?
Piping engineer world
by ellaya86
2y ago
Piping and instrumentation diagram are the piping designers roadmap for layout piping systems. The designer should understand the P&ID and the specific system characteristics. With this knowledge the designer is required to develop the P&ID and arrange connections and branches as required to best suit the process to actual physical design. The piping and instrumentation diagram (P&ID) provides a schematic representation of the piping, process control and Instrumentation which shows the functional relationships among the system components. The P&ID also provides important inform ..read more
