FlangeMatch is an offline engineering reference designed for pipefitters, boilermakers, and turnaround technicians working in refineries, offshore platforms, and industrial facilities. Built for harsh field environments with zero cellular connectivity, FlangeMatch provides instant access to standardized flange dimensions, bolt hole counts, wrench sizes, and recommended torque sequences without requiring internet access or account logins. KEY ENGINEERING REFERENCE FEATURES • Flange Dimension Tables: Rapidly look up nominal pipe sizes (NPS), pressure classes (150 through 2500), outside diameter, bolt circle, and facing thickness. • Bolting & Stud Specifications: Retrieve stud diameters, total bolt counts, stud lengths, and required heavy hex wrench socket sizes across ASME, ANSI, and API standards. • Torque Sequences & Patterns: Step-by-step cross-pattern bolting sequences to ensure even gasket compression and eliminate flange leakage. • Instant Offline Search: SQLite-powered indexing delivers instant search queries with zero input lag, even when searching deep across multi-class industrial tables. • Gasket Clearance Reference: Verify raised face (RF), flat face (FF), and ring joint (RTJ) dimensions before setting up pipe joints. DESIGNED FOR FIELD RELIABILITY • Zero Connectivity Required: Fully functional inside steel containment vessels, remote pipelines, and offshore platforms. • No Subscriptions: All reference charts and calculations are fully accessible directly upon installation. • Zero Trackers & Zero Ads: No intrusive popups or background telemetry draining battery life during turnaround shifts. • High-Contrast Interface: Clean typography optimized for high visibility in low-light industrial spaces.
