Concrete coated pipe used in submarine pipeline
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 mechanical protection to the outer coating and steel pipe of the pipeline to prevent damage to the anti-corrosion coating and steel pipe during lifting,transportation,installation and operation,to provide a negative buoyancy for the pipelines to keep the pipeline stable at the bottom of the sea (so called the weighting layer).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,and increasing the thermal insulation of the pipe and increase the resistance of the pipe to buckling stability.
