External concrete weight coating

External concrete weight coating application is performed by “impingement” method. Concrete coating is applied by continuously throwing the concrete mix on longitudinally moving and rotating pipe with protective coating and installed steel reinforcing cage and/or with the use of reinforcing wire mesh. Application of concrete weight coating allows to avoid coming of pipes to the surface and provides protection from mechanical damages. Concrete is applied on factory insulating coating. Concrete application may be performed using concrete of different densities, which makes it possible for the product to comply with different project requirements. Coating thickness can vary from 40 mm to 150 mm. Concrete application provides pipe coating of uniform thickness with minimum deviations of specified weight.
Manufactured product complies with Russian and international standards (Gazprom Company Standard, DNV, RMRS and others).
