Flange Rating Tool

Easily calculate and determine flange ratings with this powerful and user-friendly app. Designed for engineers, designers, and professionals working with piping and pressure systems, the Flange Rating Tool simplifies checking ASME B16.5 pressure-temperature ratings for every pressure class. Enter your operating pressure and temperature, pick a material and class, and instantly see the maximum allowable pressure, whether you're within rating, and how much margin you have left. KEY FEATURES • Instant results: live pass/fail verdict with a utilization bar showing how close you are to the limit — no calculate button needed. • Smart recommendations: the app tells you the minimum flange class that satisfies your conditions, and switches to it in one tap. • Rating curve chart: visualize the full pressure-temperature curve for the selected material and class, with your operating point plotted on it. • Complete rating tables: browse the full ASME B16.5 table for every class at every temperature, with your selection highlighted. • Comprehensive materials: SS316, SS316L, SS304, SS304L, SS321, and A105 across classes 150# to 2500#, with interpolation between table temperatures. • Metric and Imperial: work in barg, psig, kPag, or kg/cm²g and °C, °F, or K — switch unit systems in one tap from Settings. • History: save any check and restore it later, in whichever units you're using at the time. • Share and document: export a result as text or a clean one-page PDF report including the rating curve and full table — ideal for design records. • Beautiful and accessible: modern Material 3 design with light and dark themes and colorblind-friendly status colors. • Offline access: everything works anywhere, anytime — no internet connection needed. WHO IS IT FOR? • Engineers and designers in the oil & gas, chemical, and mechanical industries. • Professionals involved in pipeline design, installation, or maintenance. • Students and educators seeking a reliable flange rating reference tool. Make your flange rating calculations faster, more accurate, and hassle-free with the Flange Rating Tool app. Download now and streamline your engineering tasks! Note: ratings are based on ASME B16.5 pressure-temperature tables. This app is an engineering aid — always verify results against the applicable code edition and your project specifications before use.
