Industrial facilities of all kinds rely on process piping to move fluid, gas, and fine particulate matter. Process piping refers to the interconnected system of pipes or tubes that transport materials within and throughout a facility. Process piping systems may be simple and limited in scope, or they may be extensive and intricate, depending on the application. As such, it’s important to work with an experienced process piping supplier who can negotiate the many variables involved in process piping design.

As a turnkey service provider, Marshall Industrial Technologies specializes in the design, fabrication, and installation of austenitic sanitary and high-purity process piping systems. We support clients from design through installation to provide personalized, high-performance process piping across diverse industries and applications.

What is Process Piping?

Process piping comprises all the pipes, valves, and control instruments that regulate fluid and gas movement in industrial operations. Process piping systems are often used to move, separate, mix, or pressurize these media, preparing them for use in various industrial processes.

It’s important to note that not all pipes present at an industrial facility qualify as process piping. Process piping is distinct from plumbing, and it also excludes pipes used for heating, cooling, or power processing. Process piping includes only components used to support industrial applications such as mixing or transporting raw materials or products that requires the piping be free of contaminants.

Designing a Process Piping System

Process piping systems vary dramatically depending on their functions. Not only do the number and placement of pipes differ, but so do fundamental variables such as pipe materials and control elements. Designing a process piping system involves negotiating these variables to develop a system that is tailored to your unique constraints.

Key considerations in process piping design include:

Material Selection

One of the first and most influential steps in process piping design is material selection. In choosing piping and valve materials, consider the materials to be transported, as well as the application’s temperature and pressure requirements. The most common option includes stainless steel, however Inconel, Monel, Hastelloy and other specialty materials may be available to meet challenging constraints.

Installation Practicalities

No matter how complex your process piping system, keep in mind that straight routes are invariably easier to install and maintain. The simpler you can keep your pipe route, the more affordable it will be. Similarly, consider what will be feasible to install given your facility’s constraints. What makes sense on paper may be difficult to install in practice, depending on existing equipment, piping, and walls. For this reason, flexibility must be incorporated into the planned pipe route to account for natural imprecision in the installation process.


Just as a solid design allows for the practicalities of installation; maintenance, repair and cleaning must be considered. To facilitate proper upkeep, consider breaking longer sections into shorter, more manageable pipe sections. Doing so makes it easier to disassemble a localized portion of the piping for repairs or upgrades. Similarly, consider how the piping will drain before being serviced, and ensure that valves are easily accessible. Failure to consider these factors can unnecessarily lengthen the maintenance process, all while inconveniencing and potentially endangering technicians.


Functionality must be the core concern when developing any piping system. The specific application will dictate the appropriate suction requirements, pipe friction, insulation, and control valves for the system. However, rather than viewing these variables in isolation, consider how the system will function as a whole—ensure that all design elements complement one another and provide what is necessary to achieve your goals. Along the same lines, consider what happens if one component fails and plan accordingly. Finally, assess whether the system might benefit from future expansion. If so, you might end headers with a flange to make building onto the system easier.

Industry Applications

Process piping is used across diverse industries. If a facility handles gases, liquids, slurries, or fine particles, it almost certainly relies on process piping to handle those materials. Some industries that make extensive use of process piping include:

  • Oil refineries
  • Chemical processing plants
  • Food and beverage facilities
  • Power plants
  • Paper mills
  • Brewers
  • Wastewater treatment facilities

In these and other industrial settings, process piping facilitates:

  • Filtration
  • Mixing or separation of liquids or gases
  • Pressurization or depressurization of liquids or gases
  • Regulation of fluid or gas flow
