Concrete Coating For Pipe

Concrete weight coating (CWC) is a plant-applied coating, which can optimize negative buoyancy and provide pipeline protection from harsh environments and mechanical damage, meanwhile, minimize cost.

CWC pipe coating is intended primarily for submerged service for water or oil and gas pipeline system. The excellent compression resistance of concrete pipe coating meets the most stringent international specifications, and can be used to meet each project’s specific requirements in different densities.

Production Process

The concrete is prepared in an automated batching plant using aggregates (e.g., sand, iron ore), cement and water. The mix is applied on the pipe by impingement or compression while one or more reinforcing wire meshes are incorporated, depending on the required coating thickness.

Features & Advantages

- Dual purpose: acts as both a buoyancy weight and a protective layer

- Various pipe diameters can be customized

- Stabilize pipes in flowing water or at water outlets

- Coatings manufactured on-site or remotely
