Store description excerpt
Flange Hole Marker is a professional calculation tool designed to simplify flange hole dividing and marking work. The app is used to calculate equispaced flange hole marking, flange holes at any angle, and equivalent number of holes on a given pitch circle diameter. This application is widely used in piping, fabrication, flange machining, and heavy engineering industries where accurate flange hole marking is required. It helps eliminate manual calculations and improves accuracy during hole center marking on flanges and circular components. Available Calculators: Equispaced Flange Hole Marking Calculator Flange Holes at Any Angle Marking Calculator Equivalent Number of Holes Calculator Equispaced Flange Hole Marking: This calculator is used to divide flange holes equally on a pitch circle diameter or bolt circle diameter. Enter the Pitch Circle Diameter (PCD) or Bolt Circle Diameter (BCD) in mm and the number of holes. The app calculates the dividing marking distance (chord length) used for accurate flange hole marking. Flange Holes at Any Angle: This calculator is used when flange holes are required at a specific angle instead of equal spacing. Enter the Pitch Circle Diameter (PCD) or Bolt Circle Diameter (BCD) and the required hole angle in degrees. The app provides the dividing marking distance for precise hole placement. Equivalent Number of Holes: This calculator is used to estimate how many holes can be equally marked on a given circle. Enter the circle diameter and the small hole diameter. The app calculates the maximum number of holes that can be fitted on the desired circle. Key Features: Flange hole marking calculator Equispaced flange hole division Flange hole marking at any angle Equivalent number of holes estimation Uses PCD or BCD input values Accurate chord length calculation Simple and easy-to-use interface Flange Hole Marker is very useful for professionals involved in flange fabrication, flange machining, piping systems, pressure vessels, heat exchangers, storage tanks, reactors, agitators, mixers, and heavy engineering equipment manufacturing. This app is ideal for anyone who needs fast and accurate flange hole center marking without manual calculations.
