Concrete weight pipe coating plants
Concrete weight coating adds weight and mechanical protection to pre-coated steel pipes. This helps pipelines remain stable in offshore or submerged conditions, where negative buoyancy is required.
Bauhuis designs and delivers concrete weight pipe coating plants based on the required pipe specification, coating thickness, reinforcement type and production setup.
Turnkey concrete weight coating plants
Bauhuis supplies equipment for complete concrete weight coating plants. Each system is engineered around the required output, pipe dimensions, coating thickness and project specification.
A complete line can include pipe handling, concrete batching, impingement or wrap coating, reinforcement application, anode installation, curing and reclaim systems.
Impingement or wrap coating
Bauhuis supplies two main types of concrete weight coating systems: impingement coating and compression wrap coating.
In an impingement plant, high-speed rollers apply the concrete mix onto the rotating pipe. In a wrap coating plant, the pipe moves helically past an applicator belt that presses concrete and wire mesh layers onto the pipe surface.
Concrete batch plant
The concrete mix is prepared in a dedicated batch plant. Iron ore, sand, cement and water are blended to achieve the required density and coating performance.
The batch plant can include cement silos, weighing bunkers, sieving equipment, transport belts, heavy-duty mixers and reclaim systems to reduce waste and improve process efficiency.
Reinforcement and anode installation
Concrete weight coatings require reinforcement. Depending on the coating system and project specification, Bauhuis equipment can support steel cages, steel wire mesh or a combination of both.
For anti-corrosion anodes, Bauhuis supplies complete installation stations with rotators, jib cranes, welding units and backfill equipment.
Curing systems
The curing process depends on the local climate and project conditions. In hot regions, coated pipes can be wrapped and cured outdoors. In colder environments, steam-heated curing cabins can be used to control the curing process.
Bauhuis designs curing systems around the required production flow, available space and environmental conditions.
