Flange bolting data, instantly, offline.

Flange Bolt Chart puts the ASME reference tables a pipefitter actually needs into one fast, native app — and it works with no signal at all.

LOOK IT UP IN SECONDS
Type "6 300 wn" and go straight to the answer. Search understands nominal pipe size, pressure class, flange type and facing in any order, so you are not tapping through four dropdowns while standing on a scaffold.

WHAT'S INSIDE
• Flange bolting — number of bolts, bolt diameter, wrench size (standard and heavy), bolt hole diameter, drift pin diameter and stud bolt length
• Stud bolt length calculator — the full ASME B16.5 equation with every component editable, so you can see exactly where the number comes from
• Flange dimensions — outside diameter, bolt circle, hub diameter, thickness
• Gaskets — flat ring, full face, spiral wound and ring joint
• Pipe — look up by schedule, or work backwards from a wall thickness
• Bolt threads — UNC and 8UN, with pitch, minor diameter and tensile stress area
• Line blanks and butterfly valve bolting
• Torque values and tightening patterns

SEE THE JOINT
A live bolt-circle diagram draws the actual flange face — the right number of holes, in the right places — and animates the star tightening sequence pass by pass. Pinch to zoom, hand the phone to the crew.

BUILT FOR THE FIELD
• Completely offline. Every table ships inside the app; nothing is fetched.
• Large, high-contrast values you can read with a wrench still in your hand.
• Imperial and metric throughout, switchable everywhere at once.
• Every value cites the standard it came from.

JOB SHEETS
Group the lookups for a tie-in into a named job, then export the whole thing as one clean PDF for the crew or the materials list.

Reference data is drawn from ASME B16.5, B16.47, B16.20, B16.21, B16.48, B36.10M, B1.1 and PCC-1.

All values are guidelines based on published standards and theoretical conditions. Always follow the specifications provided by your client and the equipment manufacturer.
