Engineering Tools
Interactive Calculators
Real-time flange engineering tools designed to accelerate your calculations, verify ratings, and support design decisions. All calculators reference ASME B16.5 standards and published engineering data.
Available Tools
Three essential calculators covering pressure-temperature ratings, bolt torque, and dimension lookups.
Pressure-Temperature Rating
Look up maximum allowable working pressure (MAWP) for any material grade, pressure class, and temperature combination.
Bolt Torque Calculator
Calculate recommended bolt torque values based on bolt size, material grade, and lubrication conditions.
Flange Dimension Lookup
Quick reference for flange OD, bolt circle, number of bolts, bolt diameter, and thickness.
Why Use These Tools
Instant Results
No manual lookup tables or spreadsheets. Get answers in seconds. Real-time calculations eliminate transcription errors.
ASME-Aligned
All calculations reference ASME B16.5 published data. Results are for reference only. Verify against current spec or call (281) 484-8325 for certified data.
Design Verification
Verify that your selected material and pressure class meets your operating temperature requirements.
Mobile Accessible
Use on job sites, in meetings, or at your desk. Tools work on desktop, tablet, and mobile devices.
No Installation Required
Web-based tools run in your browser. No software installation, compatibility issues, or IT headaches.
Always Free
No subscription, registration, or licensing fees. Simple, straightforward access for engineers and technicians.
How to Use These Tools
1. Select Your Parameters
Each tool presents a simple form with dropdown menus or input fields. Choose your material grade, pressure class, size, or other relevant parameters.
2. View Instant Results
Results appear immediately. For pressure-temperature tool, see MAWP across a range of temperatures. For torque, see recommendations for dry, oiled, and molybdenum conditions.
3. Print or Screenshot
Print results for your project file or documentation. Screenshots capture data for sharing via email or team collaboration platforms.
4. Cross-Reference Standards
All results reference ASME B16.5. For critical applications, verify against original ASME documentation or contact our engineers for certified calculations.
Data Sources & Accuracy
All calculator data is sourced from ASME B16.5 published standards, ASME Section VIII pressure vessel rules, and industry-accepted reference materials. Results are representative and suitable for design and engineering purposes. For critical applications involving safety or regulation, always verify results against original standards or certified engineering calculations.
