Nozzle Orientation marker is developed for easy, fast and simple use of this calculator while Nozzle marking on Pressure vessel, tank or any other shell.

it simply required input of outside circumference or shell outside diameter.

this app calculate arc length required for marking nozzle on shell at a given angle.

this app is also calculate arc length required for 1 degree.

This app is very useful for fabrication fitter, Quality engineer, fabrication engineer, fabrication supervisor or production engineer.

this app is widely used in pressure vessel fabrication or process equipment fabrication.
