A Quick Introduction To Piping System Design

A highly important task is pipe system design. It necessitates an understanding of both the varied needs for designing systems and the overall process of plants. As much of any plant’s structure is made up of piping and other equipment, the pipeline design must be flawless to prevent disputes. To avoid errors in calculating stress, load, operating pressure, temperature, and many other factors, piping engineers and designers must perform their duties with the utmost care. The nervous system of a certain Process in the Thermal or Oil & Gas sectors comprise pipes of the design piping systems. The optimum method for transferring fluids, liquid water mixes, solids, air, and other insoluble materials under various situations are to use piping systems, which are mandated by process requirements. These garbage sets of connections typically experience pressure, temperature, or a combination of both. Additionally, these piping systems are once more affected by noxious conditions, corrosion, erosion, etc. Finally, it creates a delicate pipe system design that makes a mess or ensures a facility can run safely for a longer period.

Design Piping System – Contents and Coverage

The field of piping design is extensive. The following is covered and engineered for an effective process:

  • Materials for piping and its components must be necessary.
  • Stress and load calculations for pipes
  • pipe construction
  • Assembly of Piping
  • Erection Assessment Inspection of Piping
  • Pipe hydro testing
  • Costing of Piping System

Most of any process plant’s investment, barring the key equipment is spent on piping. 15% of the total cost of the materials is made up of the piping itself. Whereas 25% of person-hours are spent on the design of the piping system, 65% of person-hours are spent on detail design, which includes piping design, and 35% of person-hours are spent on implementation. 65% of the person-hours spent on detail design (DD) engineering, out of which 25% are used only for piping, and the remaining 40% are consumed by other disciplines, such as mechanical, electrical, civil, environmental, instrumentation, etc., make up the total effort put into project management, procurement, quality control, etc. A piping system’s level of precision and finesse depends largely on the As-built data of its static or rotating equipment, purchased control valves, and in-line instrumentation like flow meters and venturi meters. So, piping gas cannot be determined until the suitable equipment manufacturing timetable or vendor input. It is causing a delay in the construction drawing’s publication.

Design of Piping System – Know How

A piping designer’s expertise must extend beyond actual pipe installation. Understanding the cost of pipeline materials, metal composition, outcomes, and fabrication techniques may be a bonus for inefficient pipe design. The instrumentation is critically crucial since the plumbing system’s design is the most vital component of the fundamental knowledge of DD engineering for numerous disciplines, such as process and civil. Design Piping System is subjected to liquid or process pressure, fluctuating temperatures, and pipe expansion or contraction referred to as stresses. These stresses are then passed to several connected pieces of equipment of various designs, leading to a breakdown. Therefore, to solve these kinds of practical issues, one should be familiar with the fundamentals of structural engineering. Good engineering practices, accepted codes, and process engineering would be the cherry on top. According to legend, a plumbing engineer’s best qualities are limitless patience and the ability to visualize 3-dimensional blueprints.

Design of Piping System – Latest Techniques

To implement simple and quick solutions that produce drawings with minimal time consumption, compile pictures with maximum accuracy, and address piping stress analysis, computers, and their custom software have been developed. Bill of materials, which also includes stress analysis, as well as Plant Design and Management System (PDMS) software is the best user-friendly and cited examples; these are just a few of the numerous software programs that are being introduced to the market for effortless, uncomplicated, and accurate isometrics.

Types of Piping Design Software

They are categorized into two classes based on their features and applications of piping design software:

  1. 2-D piping design software: Although 3D software is more popular nowadays, 2D software is still used to create many isometrics piping drawings, including GAD, and P&ID.
  1. A 3D design program creates and represents every piping component and layout in a 3D perspective, which makes it simpler for the user to visualize and use the piping network physically on location.

Best 3D piping Design Software

These days, 3D piping design software is widely utilized and favored. Because it is simple to represent the entire plant architecture in a A 3-dimensional environment with the aid of these piping design tools because they are exact duplicates of natural plants; 3d models of plants are incredibly simple to comprehend. Several of the popular 3D piping design programs include:

  • SP3D by Hexagon
  • Auto PLANT 3D by Bentley
  • AutoCAD Plant 3D by Autodesk
  • CADWorx Plant Professional Par Hexagon
  • M4 plant by Cadschroer
  • Edraw max by Edrawsoft

Best 2D piping design software

With technological advancements, most businesses now favor 3D software for piping system design. However, the industry is still using 2D piping design software. Among the most popular and effective 2D piping design programs are:

  • AutoCAD
  • Micro station
  • IronCAD
  • Lucid chart


The piping system’s design is a serious task that must be handled with attention if the project is to be completed quickly, affordably, and safely. The piping system’s design is subjected to liquids, gases, and semi-solids with variable pressures and temperatures, which causes the pipes to contract and expand. A skilled designer is always aware of the following:

  • To create a successful project to reduce the execution effort.
  • to reduce the project’s overall cost.
  • The fundamentals of the plant process
  • Create a visual representation of the concepts and incorporate them into the project’s design for easier execution.
  • Put an end to disputes and conflicts between various disciplines.
