Concrete coating system is designed to provide negative buoyancy and mechanical protection for pipelines in subsea and wet environments. Compression Coat uses a side-wrap application process making it ideal for both small and large diameter pipelines. The product is available in various thicknesses and densities and can be applied over FBE or 3LPE coating.

Centerway steel co.,ltd can provide concrete coating pipe of various standards and grades, passed ISO9001, SGS and other certificates, accept third-party testing, has complete testing and testing facilities, from product development, raw material supply, production process management, etc. in accordance with international quality The system standards are standardized to provide customers with satisfactory pre-sale, in-sale and after-sale services.
