What's New in Pipe N Wire

3.1

May 30, 2025

What’s New in This 3.0 Version The all-new PipeNWire is here — completely redesigned, rebuilt, and recharged for today’s electricians. This major update is more than just a fresh coat of paint. We’ve taken everything you loved about the original PipeNWire and rebuilt it from the ground up with a faster, smarter, and more powerful experience. Whether you’re a seasoned journeyman or an apprentice, this version gives you the speed and accuracy you need on the job. Major Improvements: • Modern, Intuitive Interface PipeNWire now features a clean, easy-to-use design that works beautifully. Quickly select your pipe material, wires, and fill percentage, and get instant results. • Support for All NEC Standard Wires We’ve loaded in the most common wire types (THHN, XHHW, RHH, and more) along with their respective gauges and area values—accurate and compliant with the latest NEC conduit fill tables. • Smart Conduit Picker The app automatically centers on the smallest conduit size that meets your selected fill percentage. Easily scroll left or right to explore other sizes and see how each affects the total fill. • Save & Reload Calculations Now you can save your work! Give your calculation a name and load it anytime. Perfect for job planning, estimating, or record-keeping. You can also update saved calculations with new values. • Manual Pipe Size Override Need to choose a larger pipe size for easier pulls or future expansion? No problem. Override the recommended size and still see accurate fill data for your selection. • Persistent Preferences PipeNWire remembers your last-used pipe type, wire selection, and fill % so you can jump back in quickly and pick up right where you left off. • Built on a Modern Codebase The entire app has been rewritten in Swift using Apple’s latest frameworks. That means better performance, smoother animations, and long-term support for future iOS versions. Additional Enhancements: • Improved support for fractional and large conductor sizes • Faster performance and improved reliability • Cleaner visual layout for fill percentages and wire data • Enhanced compatibility with newer iPhones and iOS versions • Dark Mode support Thank You! PipeNWire was originally launched over a decade ago, and this update represents our renewed commitment to supporting the electrical community with accurate, job-ready tools. Thank you for your continued support, and for trusting apps like PipeNWire and iBend Pipe in your daily work. We’re always listening—if you have feature requests or suggestions, drop us a line. And if you love the update, we’d appreciate a rating or review!

APP CURRENTLY ISNT WORKING

This app is currently not working are used to work really really well before the update but after the update it does not let you select conduit. It does not let you select a size wire and it does not let you select your wire fill. Its permanently on EMT and it’s not let you choose sizes or types or anything so please fix that developers so we can get back to using it because it really is a great app!

Conduit body’s

Great little app
Conduit body fill would also be a dig help

Great app

Great app to use …. Buddies even call me all the time asking for conduit fill

Needs correction

The vast majority of wire insulation I use is T90 or RW90. Perhaps it’s an American thing, I don’t know what most of the insulation types (in this app) are in real world use.

Other wire fill apps have the two I need.

Works great for me
