Let’s start with the video.

Both pipe rack and pipe track are different. Here on the slide, you can see the difference between the Pipe rack and Pipe track.

Pipe Rack Pipe Track
Elevated steel or concrete structures Grounded or grade-level pipe support
Support all main process lines Mainly used in OSBL area to support pipelines
Steel or concrete structures Sleepers are used

Pipe tracks are grounded or grade-level pipe support, which is also known as Pipe Sleepers. Whereas pipe racks are elevated steel or concrete structures. Refer to this image to see the difference.


Pipe racks support all main process lines that connect equipment such as pumps, storage tanks, static vessels, and columns. It also connects various relief and blowdown headers. All lines leaving and entering the plant, utility supplying lines such as steam, air, cooling water, inert gas, etc., are routed through a pipeline corridor.

Main Pipe Rack and Unit Pipe Rack

The pipe rack can also be classified as Main Pipe Rack and unit pipe rack.

Main Piperack helps transfer material between units, storage, and utility areas. It connects multiple units and runs across the facility.

Whereas, Unit pipe racks are located within the unit and connect to the equipment of the unit.

Refer to the image given here; the main pipe rack and unit pipe rack are shown. I have also shown Pipe Track. You know the difference between them, as I have already explained to you.
