Concrete coated pipe also called concrete weight coating pipe (CWC pipe), it is the steel pipe external with concrete weight coating (Mixed with cement, aggregates, reinforced steel mesh and water), to provide the strong downward force protection or a negative buoyancy for the pipelines. This pipe is commonly used in sub-sea (submarine) pipelines, with adding the proper weight of the concrete coatings to support a resistant pressure against sea water.
Concrete coated pipe types and dimensions
For to use in different circumstances in the sub-sea environment, the pipe could be in different dimensions, and available with with different weight / thickness / density of concrete coatings, also can be processed with anti-corrosion coatings and insulation coatings.
