PipeSizer: Diameter Selector

Flow & Piping Tools

About this app

PipeSizer helps piping engineers quickly identify suitable pipe diameters from flow rate, fluid service, pipe material, and velocity criteria.

Enter your design conditions and compare standard pipe sizes ranked by calculated flow velocity. Each result shows whether the candidate is below, within, or above the selected velocity range, making preliminary diameter screening faster and easier to review.

KEY FEATURES

• Rank standard pipe diameters by calculated velocity
• Work with water, process liquids, hydrocarbons, and basic slurry services
• Select pipe materials, liners, and liner thicknesses
• Use traceable velocity ranges with supporting references
• Override velocity limits when project criteria require it
• Switch between SI and Imperial units
• Save and revisit sizing results
• Share calculation summaries
• Send selected results to Pump Mate for further hydraulic analysis
• Choose light or dark appearance
• Available in English, Spanish, French, and Portuguese
• Core sizing functionality works offline

PipeSizer is designed for preliminary engineering, field checks, and conceptual studies. It provides transparent calculations and references so you can understand the basis of each result.

Engineering disclaimer: PipeSizer is a screening and decision-support tool. Final pipe sizing must consider pressure loss, system hydraulics, transient conditions, erosion, corrosion, applicable codes, and project-specific requirements. Results should be reviewed by a qualified engineer.

What’s new

PipeSizer 1.1.0 brings the Google Play launch build in line with the App Store version, including the latest usability, layout, and stability polish from closed testing.
