The Pipe Coating Amount calculator computes the amount of coating material for the exterior surface area of a pipe based on the pipe diameter, length and the thickness of the coating.
INSTRUCTIONS: Choose units and enter the following:
Coating of Pipe (V): The calculator returns the volume of material to coat the surface area in gallons. However, this can be automatically converted to compatible units via the pull-down menu.
V =2π⋅(d/2)⋅l ⋅ t
Pipes can be coated with various materials to protect them from corrosion and other environmental factors. Some common materials used for coating pipes include:
The choice of coating material depends on factors such as the type of pipe, the environment in which it will be installed, and the specific requirements for corrosion protection.
The USP-0550 pressure thickness guide specifies that the outside coating shall be an asphaltic coating approximately one mil thick.
The International Organization for Standardization (ISO) 8179-1 is the standard. 200 g/m2 is approximately 1 mil in thickness.
One expert suggests that the range of thickness of paint on pipes is from 15 to 100 microns.
