A concrete coated pipe, also known as a concrete weight coating pipe (CWC pipe), refers to a steel pipe that has been externally coated with concrete weight coating (Mixed with cement, aggregates, reinforced steel mesh and water).

2020年11月3日 · The 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 strong downward force protection (Impact from anchoring, dredging activity, fishing, ship sinking) or a negative buoyancy for the ...

Concrete coated pipes, also known as concrete weight coated (CWC) pipes, are steel pipes coated with a layer of heavy concrete. This type of coating is primarily used to provide negative buoyancy, ensuring that the pipes remain submerged in underwater environments.

CWC pipes are mainly used for laying subsea pipelines, providing negative buoyancy for pipes, ensuring their stability on the seabed, and providing mechanical protection for them. The surface of the steel pipe is sequentially coated with epoxy powder coating, adhesive coating, anti-corrosion coating, concrete coating, and reinforcement mesh.

CWC pipe consist of cement, water, aggregates and reinforcement materials, it’s advantage is to fix the pipeline stably performances and provides effective mechanical protection. Compared with other insulation type like pipe-in-pipe, CWC pipe is more efficient in saving cost, easy the pipeline installation and convenient the operations.

2023年9月8日 · CWC pipe is the abbreviation of Concrete Coated Pipe, also known as Concrete Weight Coating Pipe. It is a steel pipe coated with concrete on the outside. Concrete coatings (consisting of a mixture of cement, aggregate, steel mesh and water) can provide strong downward force protection or negative buoyancy to pipes.

KELDORI SERVICES LIMITED offers a premier solution for pipeline protection with its Concrete Weight Coating (CWC) for line pipes and joints. This specialized coating is designed to ensure negative buoyancy, making it an ideal choice for offshore pipelines, as well as river and road crossing applications.

Concrete weight coating provides additional weight to an anti-corrosion coated pipe in order to provide negative buoyancy and mechanical protection for pipelines in subsea and wet sub-terrain environments.

Union Steel Industry can provide concrete weight coating pipes, which are generally used in the construction of marine pipelines, especially in the transportation of marine crude oil.

2024年10月16日 · Concrete weight coating (CWC) is a method used to apply a dense concrete layer over a pipe, primarily to provide negative buoyancy and protect the pipe in offshore or underwater environments. This process enhances the durability of pipelines by offering mechanical protection and corrosion resistance while also helping to ensure the pipe remains ...
