These are excellent surface protection coating methods using tape wrapped around a cylindrical substrate with non-barrier coating properties. They are applied along the length of the pipe.
They are mainly used in pipelines (gas, oil, water and solvent waste) and in the marine industry to provide cathodic corrosion and waterproof protection for girth welds and fittings, depending on the surrounding environmental conditions and climate.
Just like any other coating method, coating with tape produces the film and thickness needed to cover the entire surface of the pipe. They are made of polymer that can withstand tearing and abrasion. They can be combined with liquid coatings such as epoxies for enhanced surface protection.
Most industries prefer a combination of wrap and primer to create strong surface protection. These tapes or wraps can contain multiple layers of material, depending on the location and surrounding conditions. The exterior tape is usually UV tape to provide a reflective surface.
The tape coating system is a very simple method that requires the use of tape and packaging tools to facilitate the application process. This type of tape is designed for above and below ground systems. It is made of the following materials and additives:
the fabric
polymer
rubber
asphalt
petrolatum compound
