API 5L X60QS PSL2 CWC pipe, concrete weight coated pipe for sour service

API 5L X60QS PSL2 CWC pipe is shorten for API 5L X60QS PSL2 concrete weight coated pipe. The concrete coating consists of cement, water, aggregates and reinforcement materials, which are mixed in a mixer according to a specific proportion to form a special concrete. The concrete is sprayed on the outside of API 5L X60QS PSL2 steel pipe after external anti-corrosion treatment by spraying or extrusion spraying equipment, forming a concrete coating with a certain thickness together with the reinforced steel mesh. Thus can increase the weight of API 5L X60QS PSL2 steel pipe.

API 5L X60QS PSL2 CWC pipe chemical composition:

API 5L X60QS PSL2 CWC pipe mechanical properties:

The concrete coating gives added weight to API 5L X60QS PSL2 CWC pipe, enables API 5L X60QS PSL2 concrete weight coated pipe to better overcome buoyant force of the water. API 5L X60QS PSL2 CWC pipe can be used in swampy land with high water tables and also underwater pipelines.
