PI Integrated Systems is a leader in providing easy to use plant design solutions for the process and petrochemical industry. PI's FlexCAD family of equipment layout and piping design software provides highly productive 3D & 2D solutions to both owner/operators and EPC's in the design, construction and operations of process plants.

Piping design is a profession learned through experience and practiced with professionalism. Instead of making the job easier, most piping design software impedes productivity, requiring the professional piper to be both a CAD jock and computer expert as well.

PI Integrated Systems has taken a different approach to process and petrochemical plant design software, a "back to basics" approach that reflects the experience and the intuitiveness of the professional piper.

Simply put, FlexCAD software was created by pipers for pipers. Our products have been used for over 11 years, by over 3500 of some of the most demanding pipers in the business. They have used and tested our products, and told us what they need to do their job better. We listened, and the result is a family of products that work like you to fast track your design, and help you bring your projects in on-time and under-budget.
