Look up flange dimensions, bolt sizes and torque patterns in three taps with Flange Bolt.

Just enter the flange size, type, and class, and the tool instantly shows all the ASME data you need.

Here's just a sample of the available data.

Bolting data:
1. Number of bolts
2. Diameter of bolts
3. Length of bolts (stud bolts and machine bolts)
4. Wrench size
4. Torque pattern
5. Suggested torque

Flange dimensions:
1. Outside diameter of flange
2. Flange thickness
3. Diameter of bolt circle
4. Flange weight

Gasket dimensions:
1. Gasket inside diameter
2. Gasket outside diameter

And many more fields.

All values are sourced directly from ASME flange bolt charts and flange torque charts like ASME B16.5 "Pipe Flanges and Flanged Fittings: NPS 1/2 through NPS 24 Metric/Inch Standard".

Looking up flange bolt sizes and torque patterns with Flange Bolt is far faster and less error prone than searching through PDF charts and tables. The sole purpose of the tool is to make it as simple as possible for a pipefitters, steamfitters, and others working in piping to look up flange bolt size and torque pattern information.

Is there a feature you'd like from Flange Bolt that you don't see? Request it through the app and we'll do our best to add it to the development schedule.

Features of the app:
1. Full offline capability: No internet connection necessary to use. All data is stored locally on your phone. (The app requires minimum storage space overall)

2. Instant flange bolt sizes and torque patterns: Just enter the flange size, class, and type and the app instantly populates the correct values from the flange bolt size chart and the flange torque sequence chart, along with wrench size.

3. Flange torque sequence image: Each lookup shows the correct flange torque sequence image in picture form, with the studs numbered.

The information in this app covers:

(1) flanges with rating class designations 150, 300, 400, 600, 900, and 1500 in sizes NPS 1/2 through NPS 60 and flanges with rating class designation 2500 in sizes NPS 1/2 through NPS 12, with requirements given in U.S. Customary units with diameter of bolts and flange bolt holes expressed in inch units;

(2) flanged fittings with rating class designation 150 and 300 in sizes NPS 1/2 through NPS 60, with requirements given in U.S. Customary units with diameter of bolts and flange bolt holes expressed in inch units;

(3) flanged fittings with rating class designation 400, 600, 900, and 1500 in sizes NPS 1/2 through NPS 60 and flanged fittings with rating class designation 2500 in sizes NPS 1/2 through NPS 12 in U.S. Customary units.

Covers 4 bolt to 60 bolt sequences.
