Tools
Compliance starts at the bench, not the binder.
Four calculators for the numbers a weld shop checks every week. Free to use, nothing to sign up for, each one worked step by step, with a unit conversion table beneath it.
Heat input
Arc energy from voltage, current and travel speed or run length and time. ISO method with a thermal efficiency factor, or the ASME IX method without one.
Open the calculator →Minimum wall thickness and MAWP
Pressure design thickness for straight pipe under internal pressure, and the allowable pressure for a wall you already have. Choose a pipe size and schedule, and type the stress and the factors.
Open the calculator →Blank thickness
Minimum thickness of a flat blank (a spade or a blind) from the gasket diameter, the design pressure and the allowable stress.
Open the calculator →PED/PESR calculator
The conformity assessment category for a vessel, a pipe or a steam generator from the pressure, the volume or size and the fluid, with the working shown.
Open the calculator →For guidance only. Verify against the code edition in force and your own design basis. These tools do not store anything you type.
