Pipe Coating Amount

Processing...

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:

(d) Diameter of Pipe (use exterior diameter)
(l) Length of Pipe
(t) Coating Thickness
(n) Number of Pipes to Coat

Coating of Pipe (V): The calculator returns the volume of material to coat the surface area 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 coating for a pipe is:

V =2π⋅(d/2)⋅l ⋅ t

where:

V = Amount (volume) of Pipe Coating
d = Diameter of Pipe
l = Length of Pipe
t = thickness of coating

Pipe Coating Guidelines

Pipes can be coated with various materials to protect them from corrosion and other environmental factors. Some common materials used for coating pipes include:

Epoxy Coatings: Epoxy coatings are often used to protect pipes from corrosion. They provide a durable and chemically resistant layer.
Polyethylene (PE) Coatings: PE coatings are applied to pipes for corrosion resistance and to provide a protective barrier against moisture and chemicals.
Polypropylene (PP) Coatings: PP coatings are similar to PE coatings and are used to protect pipes in corrosive environments.
Fusion-Bonded Epoxy (FBE): FBE coatings are applied using a heat treatment process to create a strong bond with the pipe surface, offering corrosion protection.
Coal Tar Enamel (CTE): CTE coatings have been traditionally used for corrosion protection, although their use has decreased due to environmental concerns.
Zinc Coatings: Zinc coatings, such as hot-dip galvanizing, are effective in preventing corrosion. They provide a sacrificial layer that corrodes instead of the pipe.
Asphaltic Coatings: Bituminous coatings, made from asphalt or coal tar, offer protection against corrosion and are often used for underground pipelines.
Concrete Coatings: Concrete can be applied as a coating for pipes, especially for those buried underground. It provides physical protection and can resist environmental conditions.
Corrosion Inhibitors: Some pipes are coated with corrosion inhibitors that help prevent the corrosion of the pipe material.

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.

Coating Thickness Guidelines

Asphaltic Coating

The USP-0550 pressure thickness guide specifies that the outside coating shall be an asphaltic coating approximately one mil thick.

Zinc Coating

The International Organization for Standardization (ISO) 8179-1 is the standard. 200 g/m²is approximately 1 mil in thickness.

Paint Coating

One expert suggests that the range of thickness of paint on pipes is from 15 to 100 microns.
