Definition - What does Tape Coatings mean?
These are state-of-the-art surface protective coating methods that use tapes that are wrapped around a cylindrical substrate with non-shielding coating properties. They are applied along the length of the pipes.
They are mostly used in the pipeline (gas, oil, water and solvent waste) and marine industries to provide a protective shielding against cathodic corrosion and waterproofing on girth weld joints and fittings depending on the surrounding environmental conditions and climate.
Corrosionpedia explains Tape Coatings
Just like any other coating method, the use of tape coatings can produce membranes and thickness necessary to cover the entire surface of a pipe. They are made from polymers, which can withstand tear and abrasion. They can be used in conjunction with liquid coatings like epoxies to enhance surface protection.
Most industries prefer the combination of wraps and primers to create a strong surface protection. These tapes or wraps can contain multiple layers of the material depending on the location and surrounding conditions. The outer tape is normally a UV tape to provide a reflective surface.
The tape coating system is a very easy method that entails the use of the tape and a wrapping tool to facilitate the process of application. This type of tape is designed for above and underground systems. It is made from the following materials and additives:
- Petrolatum compounds
