Coating Steel Pipe Bituminous Asphalt Coating Coated Pipe vs. Bare Pipe

Southland Pipe offers several types of steel pipe coating processes. The pipe for sale from our yard is sold as is, bare pipe, meaning, there's no coating, inside or outside. There are multiple options for coated pipe for every order. When you request a particular coated pipe, coated inside and/or coated outside, you have a choice of applications for pipe as large as 72"OD.

º Shot Blast & Sand Blast Cleaning available
º Bituminous Asphalt steel pipe coating available (Fast and least expensive)
º Coal Tar Epoxy Coating (Typically applied in two coats, 16 mil minimum)
º Multi-Coat Exterior and Interior Paint systems, Polyurethane, and Tape Wrapping also available

Bare steel pipe will eventually corrode, or rust. Since the total performance of a pipe coating system involves the three separate processes, application to the pipe, handling and storage of the pipe, and in-ground or above-ground service of the pipe; the functional requirements and the resistance to deterioration should be considered when establishing your criteria for the coating properties that we offer.

Bituminous Asphalt Coating

The principal uses for asphalt coatings include internal and external application to carbon steel pipe. Our bituminous asphalt coating has been tested to meet ANSI-A21.4 and AWWA C104 specifications for potable water, and has been found to be acceptable and is certified to NSF Standard 61. This coating is black in color. When applied correctly, this fast coating process provides the cathodic protection required for most underground structural steel pipe. This is the least expensive method we offer for pipe coating for cathodic protection, and we are able to provide reliable response times because this is the least complicated coating process that we offer. Primarily used for road bore casings and other casing pipes.

Epoxy Coating - Sprayed Application

Typical applications include heavy-duty service conditions such as chemical plants, bridge piling structures, and pipelines. Excellent resistance to immersion in salt-water, above ground extreme temperature swings and abrasive wear and tear.
