Compressed Air Piping Layout

Transair Aluminum Piping

Pipe Material
Traditionally, engineers have specified a variety of piping materials for compressed air systems, including black iron, galvanized steel, copper, and stainless steel. More recently, aluminum piping has become the preferred option considered by mechanical contractors, architects and engineering firms. Some of the disadvantages of these systems versus aluminum include labor intensive installation, corrosion problems, prone to leaks, costly to repair or may pose safety concerns and often other systems are hard to modify.

Diameter Considerations:
The cost of compressed air frequently represents a high proportion of the initial cost of a compressed air system. While smaller diameter pipe will help save on capital cost, the restriction due to the small pipe causes greater pressure drop throughout the system, thus increasing energy consumption. Those higher energy costs can quickly exceed the price of larger diameter piping.

Layout Considerations:
The ideal distribution system provides an optimal supply of compressed air at the required pressure to all locations. The layout of compressed air pipelines, however, creates friction and results in pressure drop. Pressure drop in a compressed air piping system should be no more than 1 to 2% of capacity.

Strategies to Reduce Pressure Drop

Install the compressed air main piping in a loop or grid, so that there are multiple paths for air to travel to any location. Even in a simple loop, there are two paths for air to get to any user. If this halves the flow traveling in each direction around the loop, then pressure drop is reduced to ¼ of the level that would be seen in a single trunk line of the same pipe size.

Always use full port valves that do not reduce pipe diameter. Ball valves are preferred, but butterfly valves can be a good choice, as long as the seal materials are compatible with compressed air, moisture, and compressor lubricant.

Install isolation valves at many locations in the air mains. This allows small sections of the main to be shut down to accommodate expansions, additional drops, or pipe modifications without shutting down the entire air system. This reduces the temptation to split undersized air drops to many machines whenever an additional drop is required.

Install periodic drip legs from the bottom of the air mains. These should be used only for draining contaminants and/or checking air quality. If the system is being installed new, and is not of an easily modified material, consider placing a tee and valve at each pipe coupling, so that an outlet is never more than 10 feet down the air main.

Limit use of elbows, minimize changes in the direction of airflow, remove constrictions, reduce excessive pipe lengths and isolate unused compressed air piping because it may be a significant source of air leaks.

It is important to note that improper or incorrectly applied piping and material in a compressed air system can result in mechanical failure, damage, and serious injury or death. For assistance in your next piping layout, please contact us regarding our take-off services.

BIM Models (Autodesk REVIT)

BIM (Building Information Modeling) is the process of creating a cohesive 3D model of a construction project. These models allow for revision management, coordination, and design review throughout the life of the project. BIM allows for quicker construction, while lessening the chance for clash and costly job-site redesigns. 

Every element of a construction project is modeled to prevent clash of infrastructure systems. By using BIM, the engineer responsible for the compressed air system can see where the fire suppression system will be and design accordingly. All the key players of the project can view a simulation of the project and see what the finished product will look like. 

Parker chose Autodesk Revit format for their BIM compatible files. Revit is widely used by engineers, architects, and construction professionals.

Design Software

Parker Transair offers a design software program to help you produce system layout drawings and quotations for your compressed air, vacuum, or inert gas aluminum systems. 

Using a 3D grid, you can build the piping layout and the software will generate a bill of material with all the components and pipe sections necessary for the final product. Our design software is ideal for straightforward layouts. For more complex layouts, you will want to use either our Revit or CAD files.

TCM Site Survey

Compressed air is one of the most critical and expensive utilities in any manufacturing facility. That said, the health of the compressed air system is often times overlooked. Parker developed the Transair Condition Monitoring (TCM) system to give you an insider's look into what is going on in your system. With wireless sensors and a cloud-based monitoring platform, you can have 24/7 access to the health of your system. 

Knowing what and where to monitor can be a challenge. To help, Parker's team of compressed air experts will come to your site and help you to identify what to monitor and where to place the sensors. Through an extensive questionnaire and plant tour, our experts will identify your paint points and recommend a monitoring solution to meet your needs.

Compressed Air Piping Installation Guidelines

When installing compressed air piping, always adhere to the following installation guidelines to reduce the risk of injury:

•Calculate expansion/contraction of system prior to installation.
•Complete all tests, inspections, and compliance checks prior to pressurization
• Protect pipe from mechanical impact.
• Avoid rotation of pipe and supports as well as loosen the nuts during installation.
• Avoid installation within a solid mass (concrete, foam, etc.) without proper protection.
• Do not hang external equipment on pipe, use pipe as support for electrical equipment, or expose pipe to chemicals that are incompatible with components.
• Vent piping sections prior to maintaining or modifying the system.
• Use only Transair components and accessories throughout the system, including pipe clips and fixture clamps.
• Install pipe with two supports per 10' length, and three supports per 20' length.
• Examine all hoses and connections to see they are in good condition before pressurizing the system.
• Never point the air hose nozzle at any part of your body or at any other person. Never look into the end of a compressed air device or kink the hose to stop airflow.
• Do not use a pipe wrench to tighten fittings on 1/2", 1", and 1 1/2" pipes.
• Use flexible hose to absorb vibrations and always use an anti-whiplash strap.
• Never cut the pipe with a saw.
• Always carefully chamfer and deburr the pipe after cutting or drilling pipe.
