Process plants and engineering projects rely heavily on piping design. Piping engineering involves designing efficient pipework systems to move gasses and liquids safely within manufacturing facilities. A well-designed piping system can maximize space utilization, facilitate construction, reduce maintenance expenses, be easier for staff members to access, and increase overall system performance.
Introduction Of Piping Design
Piping systems provide vitality to modern life. Cities rely on them for waste transport from homes, businesses and public facilities to the treatment plant or point of discharge; water from sources to points of distribution; crude oil pipelines transport it from oil wells for processing or tank farms for storage purposes while natural gas distribution occurs through channels from storage tanks directly into power piping plants, businesses or homes requiring its usage; also these pipelines transport natural gas between sources and destinations - power generation plants being one.
Pipelines are widely employed within chemical plants, paper mills, food processing facilities and similar industrial sites to transport liquids, chemicals, mixtures, gasses, vapors or solids from one location to the next. What is piping design? Piping systems are essential components of healthcare facilities that utilize gasses and liquids therapeutically for treatment, while laboratory piping systems transport gasses, chemicals, vapors and fluids necessary for research and development. Just as our bodies depend on arterial walls for support, piping systems also play an integral part in modern civilization.
Pipe piping refers to all components that contain pressure - pipe fittings, gaskets, bolting gaskets, valves, pressure-containing sections of other piping components and their pressure-containing sections - such as pipes. To avoid overpressurization and stressing these pressure-containing elements, hangers, supports, and other items may also be included under its purview. Naturally enough, lines fall under this classification when joined with fittings, valves or mechanical equipment and appropriately supported by hangers/supports - also called 'pipe sections.
The Extent Of Piping Design
Pipe design encompasses the task of connecting equipment to suitable piping components selected by process engineering teams for connection; analogous to how human veins connect major organs, the scope of piping design is often described in terms of the veinlike links that comprise it.

The Fundamental Components Of Piping Design
Piping design should meet all applicable safety regulations and laws to ensure proper installation of accessories, Piping and equipment - including fundamental components of piping design are mentioned below - at once.
Plant Configuration
- Fire, Leakage, Simple Evacuation, Safety Showers, Eye Wash, Dropdown zone, crane, forklift, hose station, platform, ladder, and stairs are examples of maneuverability and maintainability.
- Cost: Material and equipment optimization, economical layout
- Constructability: Space for fabrication, the ability to move and erect large equipment, and the order in which things are built
- Other factors include weather, wind direction, location, pertinent regulations, product in/out, utilities and drain location, battery limit conditions, and future expansion area.
Piping engineers start by developing the site plan, followed by unit and overall plot plans; unit plot plans are the most critical element. Major piping development begins after implementing unit plot plans; pipe racks may even be included.
- Studies on pipe routing and orientations for ladders, platforms, and nozzles are developed.
- Since underground work is where construction begins, underground Piping is prioritized.
- We identify lines to be stress analyzed based on the size, temperature, pressure, type of flow, and equipment type to which the cable is connected. With the aid of programmes like
- Conduct stress analyses.
- Nozzle orientation for equipment in pipe routing studies.
Underground Piping
Underground Piping refers to pipes that are concealed below the surface to optimize plant design and construction processes by finding ways to connect each process to various utilities in an effective manner. Underground Piping includes trench, sewer and cooling water systems among its range.
- Location of the equipment foundation
- Underground instrument and electrical lines
- Information about civil/structural issues
- road design, etc.
Workflow Is A Necessary Input For Piping Design
- Required Input: Our input requirements cover various disciplines' deliverables, such as structural arrangement drawings, cable layouts and level sketches for instrumentation, PFD/P&ID documents, vendor prints, line lists and data sheets.
- Piping Activities: Activities related to Piping include creating site plans, overall plot plans, unit plot plans, job instructions, project specifications, materials take-off (MTO), rack sizing and orientation, as well as modeling equipment and Piping layout outlines and stress analyses, among many other duties.
- Outputs For Piping: Installation Services include site plans, overall plot plans, unit plot plans, nozzle orientation, full 3D model and isometrics as examples of outputs; MTO (piping Materials Testing Office), project specifications; GA drawings of GA pipe supports with special support index/data sheets MTO support MTO insulation/paint MTO as outputs as well as project specifications are examples of outputs; all these outputs from pipe installations will contribute towards producing their respective specifications for these specifications projects.
Statutory Requirements' Importance In Piping Design
Legal and Administrative Requirements for Piping Designs:
- Any country's statutory and regulatory requirements govern a plant's design when it is established there. Here are a few instances:
- The Explosive and Petroleum Safety Organisation (PESO): As a statutory authority, PESO is tasked with enforcing the Explosives Act of 1884, the Petroleum Act of 1934, the Inflammable Substances Act of 1952, and other related acts with the overall goal of guaranteeing the safety and security of the public and property against fire and explosion.
- Oil India Safety Directorate (OISD): for instance. OISD-STD-117: Fire Protection Facilities for Petroleum Depots and Terminals, OISD-STD-118: Layout for Oil and Gas Installations, etc.
- Relating to the Environment and Pollution: additionally to be adhered to, such as the permitted rate of NOx and SOx emissions.]

Coordination Of The Interior And External In Piping Design
Since engineering teams from multiple fields often overlap with pipe design codes work, piping stress engineers must collaborate closely with these departments while still possessing an in-depth knowledge of their plant's overall operation.
- The engineering group's upstream discipline is the process. Process requirements data sheets (PFD), P&ID, equipment lists, line lists, etc, are provided by the industrial processes.
- We receive the Mechanical Data Sheet of Equipment from the mechanical group. Vendor Prints (VPs) are the final stages of design pressure that are made available.
- The necessary foundation for machinery, rack and equipment structures, underground trenches, pits, structures for various pipe supports, etc, are provided by the Civil/Structural/Architectural group.
- The instrumentation group provides a wide range of data for control valves, relief valves, and inline and online instruments.
- Electrical provides cable layouts, drawings for classifying hazardous areas, etc.
- Preparing the plot plans is another task for each of these disciplines.
- The piping design temperature greatly impacts the construction, operation, and function of a plant.
- Depending on the project's size, construction and procurement may be an internal or external group.
- The client is the most significant external group to coordinate with.
- Other outside organizations include the PMC and the Licensor. They both have equal significance. ITB should be carefully read to comprehend the code requirements for the Licensor and PMC.
Classification Of Piping
Classifying pipes according to pressure-temperature rating systems used to categorize flows is standard practice within the industry. Rating should not necessarily depend upon determining the weakest pressure-containing component; an inferior material or one with lower ratings due to design considerations could become the weakest link within an interconnected piping system; it also provides custom solutions, innovative solutions, consulting services and stress analysis.
Class ratings governed by ASME B16.1, B16.3, B16.24 and B16.42 standards may also be employed to classify Piping. There may also be specific pressure and temperature ratings used on systems not covered by any such measure. Pression nominal (PN), representing the approximate pressure rating in bars, is one rating designator used to identify bar ratings with designation numbers. One bar equals 14.5 PSI or 100 Kilopascals Pa (kPa). Pressure units of measurement use bars. Table A1.2 offers an interactive crosswalk between ASME class ratings and PN rating designators, in which class numbers provide proportional relationships among their various PN numbers while their ratings don't. Therefore, it would be more beneficial to identify each rating by class numbers rather than simply numbering each with designation or class numbers.
Components Of Piping
Piping is any system composed of pipes, fittings, flanges, valves and other parts comprising a conduit system for fluid conveyance. Piping specifications are essential in structure and functionality - whether used to move fluid from location to location or process and condition fluid. In an extensive chemical processing system, this could involve many more parts than just valves and fittings being present, while more basic conveyance systems might contain only valves and fittings as the only essential pieces composing their structure and functionality - purposes and components of Piping design will be further explored below in subsequent sections.
Products For Pipes And Tubes
Pressure pipe and tube products are manufactured using various materials, techniques, and standard specifications that meet multiple designs. Their final user must select an inexpensive product appropriate to service conditions; steel pressure piping comes in cast, wrought and seam-welded forms, for example; their wall thicknesses comply with ASME while stainless steel pipes meet ASME requirements.
Tubing Under Pressure
Pressure tubing is commonly found in external heat applications like boilers or superheaters. Pressure tubing is designed according to each buyer's minimum or average wall thickness and outside diameter requirements; two finishes of pressure tubing exist: hot and cold. Wall thickness may not always be expressed in terms of gauge numbers but fractions of an inch instead - when gauge numbers are mentioned without specifying an overall system like Birmingham wire gauge (BWG).
