Pipe Checker Pro for Windows (developed by Air Design, Inc. Air - Sekkei) is an extremely compact and powerful dedicated software for Mechanical Engineering and Electrical (MEP) engineers, especially in the field of HVAC and Water Supply and Drainage.
Along with "brother" Duct Checker Pro (calculating the wind sock), The Tube Checker Pro is an indispensable pocket tool for calculate and select pipe size (diameter) quickly and accurately.
Core Features of Pipe Checker Pro
- Automatic pipeline size selection: Based on the flow rate or design payload, the software automatically calculates and gives the appropriate pipe size.
- Pressure loss (Ma close): Accurate display of pressure drop (friction loss per meter pipe length – $mmH_2O/m$ or $Pa/m$) and actual water velocity in the chosen pipeline to ensure smooth, optimal operation of the system.
- Support for a variety of pipe materials: It allows calculation on a variety of common pipes in the industry such as steel pipe, copper pipe, plastic pipe (PVC, PPR, PEX) etc., giving engineers flexibility to apply it to chiller systems, condenser systems or plant water supply and drainage systems.
- Smart traffic conversion: It automatically converts the Fiery Units into the actual simultaneous water flow.
- Visual custom interfaces: Supports flexible unit changes, bright/dark interface (Theme) switching and saving selection criteria for reuse for later projects.

💡 Notable advantages
- Ultra Light & Convenience: The software is very small, has a minimal, intuitive interface, and can be run directly (Portable version) without any cumbersome installation.
- Fast processing speed: Instead of having to manually look up the pressure loss table that takes time, you just type in the parameters and press
Enterto get immediate results.
Operating system environment & settings
- Operating systems support: It is well compatible on Windows (from Windows XP, 7, 8 to Windows 10 and Windows 11), supporting both 32 - bit and 64 - bit platforms.
If you're doing a plumbing design air conditioning (Water Chiller), a fire safety system or a plumbing system, Pipe Checker Pro It's a powerful assistant who can standardize pipe diameters in a matter of a few clicks. Do you need specific instructions on how to enter the parameters to calculate a particular type of pipe?
