## What is Flange AR?

Flange AR is an innovative measurement tool designed for piping engineers, maintenance operators, and industrial professionals.

Missing or worn-out flange specification marks usually mean interrupting fluid flow and unfastening bolts just to measure dimensions. Flange AR solves this by combining Augmented Reality (AR) and AI technology, allowing you to accurately identify flange specifications on-site without any disassembly.

Key Features:

Zero Disassembly Required: Measure flanges on active pipelines without stopping fluid flow or unfastening bolts, saving valuable maintenance time.

Global Standards Database: Instantly cross-reference dimensions with major international standards, including ANSI (B16.1), BS/EN (4504), JIS (B 2210), AS (2129), and ISO (7005-1).

Wide Measurement Range: Supports a comprehensive range of pipe diameters from 15mm to 600mm (1/2" to 24").

Smart Recognition: Advanced AI-assisted detection ensures accurate dimension determination, even in partially occluded industrial environments.

Instant Photo Documentation: Automatically append the retrieved flange specifications directly onto your captured photos for easy reporting, sharing, and record-keeping.

Save time, eliminate guesswork, and elevate your pipeline maintenance efficiency with the world's first AR flange measurement app.
