Detail Engineering of Piping Systems
                     Detailed Engineering of 
Piping Systems
What is Detailed Engineering ?
 An integral part of the engineering design process
 Creates detailed scope of work for every aspect of project development
 Applicable across many industrial and process engineering areas such as utility, chemical, pulp and paper
 An important deciding factor for an engineer as it provides the background plan necessary for designing and 
engineering of piping assignments.

Detailed Engineering In a Nutshell 
 In a nutshell, detailed engineering includes
 Development of P&IDs
 Development of detailed drawings, including isometrics and stress analysis
 Development of detailed drawings related to electrical facilities, instrumentation and civil works
 Supplier management
 Cost and schedule control
 Equipment procurement
 Economic evaluation
 Environmental impact
 Start-up procedures
Piping Detailed Engineering: The Process
 Includes all the components of piping system like pipe, valves and fittings.
 Involves the design and engineering of piping systems including piping components and supports, equipment 
selection & size, instrumentation & control.
 The process involves designing and developing piping & instrumentation diagrams also known as P&IDs, 
equipment plot plans, defining the piping arrangement and creating fabrication drawings.
Piping Detail Engineering: What is Involved ?
 Piping Design Engineering
 Piping 2D/3D Modeling  Preparation of piping material specifications 
 (PMS)Preliminary Piping Layout

 Preparation of Line list according to P&IDPreparation of preliminary & detailed GADs, 
BOMs/ MTOs etc.  Preparation of Isometrics
 Preparation of equipment Datasheets  Final GADs/BOM
 Preparation of design basis and standard 
drawings
Piping Detail Engineering: What is Involved ?
 Pipe Stress Analysis
 Preparation of Critical line list from piping line 
list according to design standard
 Modeling in software like CAESAR II and 
AutoPIPE form isometrics
 Prepare stress isometrics
 Nozzle data sheet
 Make report from CAESAR II and AutoPIPE
Piping Detail Engineering: What is Involved ?
 Pipe Support Engineering
 Special supports preparation
 Preparation of data sheets and requisition for 
pipe supports
 Pipe Support Layouts
 Pipe Support Detail Drawings
 Pipe Support Markings based on industry 
standards and special requirements
 Standardization of Pipe Supports
Piping Detail Engineering: Who’re Involved
 Engineers, designers, draftsman and CAD operators in piping design & engineering industry.
 An expert in the field of piping detailed engineering.
 The experts help fabricators and contractors in calculating the cost and get a better understanding of design, 
layout and construction of piping systems
Detail Piping Engineering: How does it help ?
 Detail piping engineering helps to 
 Know how your piping system should work.
 Decide what material must be used to make the piping structure of the engineering project
 Select the type of material for certain pipes and piping components
 Draft fabrication and construction specifications
 Helps engineers to execute a thermal analysis, vibration analysis and stress analysis for sound piping layout and 
implementation
To Conclude
 Piping Detail Engineering involves multiple aspects not only related to 
piping but also involves related equipment selection and process & 
instrumentation control. Hence, it requires utmost accuracy and 
expertise to ensure that piping system doesn’t fail under any kind of 
situation.
