Note1: calculations are provided for estimation only. Actual tape requirements may vary depending on application method, real coverage, and extra.
Note2: For estimating paint consumption, use an equivalent pipe length of 1.5 × pipe diameter for elbows and 2.8 × the largest branch diameter for tees. Examples: 42″ × 24″ × 12″ Tee = 2.8 m of 42″ pipe surface
Online free tool for calculate wrapping Tapes used to cover the under ground pipes to protect them from corrosion.
The standard formula to calculate the total paint required is:
Where:
A: Total surface area of the pipe (m2).
DFT: Target Dry Film Thickness in microns.
Volume Solids (%): The percentage of solid material in the paint (e.g., enter 65 if it is 65%).
LF: Loss Factor expressed as a decimal (e.g., enter 0.30 for a 30% paint loss/overspray).
10: A constant conversion factor that aligns microns, square meters, and liters.
The standard formula to calculate the total paint required is:
Where:
A: Total surface area of the pipe (m2).
Theoretical Coverage: The area one liter covers at the specified thickness, given in m2/Liter.
LF: Loss Factor expressed as a decimal (e.g., 0.25 for 25% waste)
Volume Solids represents the percentage of the liquid paint that remains on the surface as a solid, dry film after the solvents have completely evaporated.
Note1: If a paint has 60% volume solids, it means 40% of the wet paint layer will evaporate into the air, and 60% will stay on the pipe as protection.
Note2: Usually Paint Volume Solids mentioned in the paint data sheet.
Note3: If your target DFT is 150 microns and the paint’s Volume Solids is 60% (0.60), the painter must apply a wet layer of 250 microns
This is the total external surface area of the pipe cylinder that needs to be painted. It determines how much paint you need to buy for the project.
Where:
A: Surface Area (typically in square meters)
D: Outside or inside Diameter of the pipe (in meters)
L: Total Length of the pipe (in meters)
