This calculator is designed to aid piping engineers piping students pipe welders pipe assemblers and so on!
It's a regular scientific calculator with build-in piping equations and formulas as shown below:

✔ Uses International System of Units (SI) or United States Units (US)
✔ Can use degrees or radians
✔ Have a memory mode which can store as much data as you want
✔ Come with a pipe and fittings database according to ASME standard code (ASME B36.10 for pipes and ASME B16.9 for fittings) where you can get dimensions and weights
✔ Have a material database according to ASTM standard code
✔ Calculate the volume of welding material needed to weld pipes
✔ Calculate flow rate velocity and pipe diameter
✔ Can find the closest standard pipe just by giving the inner diameter and thickness
✔ Calculate Complex Roll Offset Simple Roll Offset Mitered Cut Back Parallel Cut Back Cut Length Odd Angle Water Column Area Volume
✔ You can change the calculator color (black or white)
✔ Have a build-in converter which can convert pressure temperature length weights power and volume

Oh and it come with a manual in pdf format so you wont get lost! :)

Much more will be added in the followings updates!
