The concrete layer adds additional weight to pipes to compensate the buoyancy of submarine pipelines, and it also provides protection from external influences.
How it Works
During the concrete weight coating process, concrete is applied onto the pipe.
Impingement: 3LPE/PP-coated pipes with weld cage or wire mesh reinforcement. Concrete is sprayed at the pipe by high speed application drums.
Compression: FBE or 3LPE/PP coated pipes with concrete wrapped around the pipe along with wire mesh reinforcement.

Wire mesh or caging system
Concrete mixing/batching plant
Concrete application equipment (impingement or compression)
