API 5L X52QS PSL2 concrete weight coating pipe, CWC pipe for sour service

The coating of API 5L X52QS PSL2 concrete weight coating pipe or CWC pipe consists of cement, water, aggregates and reinforcement materials, which are mixed in a mixer according to a specific proportion to form a special concrete, which is sprayed on the outside of API 5L X52QS PSL2 steel pipe after external anti-corrosion treatment by spraying or extrusion spraying device, forming a concrete coating with a certain thickness together with the reinforced steel mesh, so as to increase the weight of API 5L X52QS PSL2 steel pipe to overcome the buoyancy of the sea or water to the pipeline.

API 5L X52QS PSL2 concrete weight coated pipe chemical composition:

API 5L X52QS PSL2 concrete weight coated pipe mechanical properties:

The concrete coating can give proper weight adding to API 5L X52QS PSL2 concrete weight coating pipe, to support a resistant pressure against the water. So that the API 5L X52QS PSL2 CWC pipe can be used in swampy land with high water tables and also underwater pipelines.
