iron ore concrete weight coating

iron ore concrete weight coating kwaksmolle

The concrete mixture is made up of iron ore, aggregate, cement and water and is applied to the pipe with a speed of approx. 190km/h. The concrete coating doubles the weight of the pipe to about 24 tonnes for added stability on the seabed and to provide mechanical protection during handling, transportation and laying operations.
