Paint for Pipes

The Paint for Pipes calculator computes the amount of paint needed to cover the exterior surface area of a pipe based on the pipe diameter, length, number of coats and the recommended area coverage of the paint. 

INSTRUCTIONS: Choose units and enter the following:

• (D) Diameter of Pipe (use exterior diameter)
• (L) Length of Pipe
• (nCT) Number of Coats
• (n) Number of Pipes
• (CVG) Area Covered by 1 Gallon of Paint

Paint for Pipes (V):  The calculator returns the volume of paint in gallons (or quarts) and liters (or milliliters).  However, these can be automatically converted to compatible units via the pull-down menu.

The Math / Science

The equation for the amount of paint for a pipe is:

    V =2π⋅(D/2)⋅L ⋅ (1 gallon / CVG)

where:

• V = Amount (volume) of Pipe Paint
• D = Diameter of Pipe
• L = Length of Pipe
• CVG = Coverage Area per Gallon

Paint Calculators

• Paint for a Room: Computes the number of gallons of paint or primer needed to paint an entire room, the four walls and ceiling and also for just the walls.
• Room Paint Cost: Estimates the cost of paint or primer needed to cover a rectangular room (blue in diagram) based on the length, width and height of the room.
• Paint for a Wall: Computes the number of gallons of paint or primer needed to paint a wall or any rectangular area (wall or ceiling).
• Cost to Paint a Wall: Estimates the cost of paint or primer needed to cover a wall or other area defined by a length and a height or width.
• Ceiling Paint Cost: Estimates the cost of paint or primer needed to cover a ceiling of a rectangular room based on the length and width of the room.  
• Exterior Paint for a House: Computes the number of gallons of exterior paint for a gabled building like a common house based on the dimensions, number of large and small windows, number of doors and the number of coats of paint
• Wood Stain Calculator: Computes the amount of wood stain to finish wood surfaces based on a length, width and the stain product coverage defined by a container size and coverage per container.
• Deck Stain and Sealer: Computes the number of quarts of stain and sealer needed for a deck based on the size and whether rough or smooth.
• Paint for Pipes: Computes the amount of paint needed to cover the exterior surface area of one or more pipes based on the pipe diameter, length, number of coats, number of pipes and the recommended area coverage of the paint. 
• Paint for Corrugated Surfaces: Computes the amount of paint needed for a corrugated surface based on the dimensions of the corrugated surface area (length and width), a corrugation factor, coverage per gallon of paint used and the number of coats of paint.
• Paint for Gambrel Wall: Computes the gallons of paint needed to cover a wall under a gambrel shaped roof.
• Paint Pricing Survey: Dataset containing a history of periodic pricing for paint products including primer and three price points (economy, medium and premium) paint.  Data comes from nationally advertised prices on the website of national retailers.
• Barn Paint Calc: Computes the amount of paint needed for the surface area of a barn (not the roof) including the sides under a gambrel roof and the sides.  This is based on the barn's span, length, total height, and height and width of the loft and coverage of the barn paint.
