EXTERNAL COATING SOLUTIONS
External Three Layer Polyethylene / Polypropylene [3LPE / 3LPP] Coating
Ratnamani's 3LPE/ 3LPP Coating is a multilayer coating composed of three functional components. This coating consists of the first layer which is a high-performance anti-corrosion fusion bonded epoxy [FE] second layer of a copolymer PE/PP adhesive for adhesion between the epoxy and PE/PP and an outer/third layer of polyethylene / polypropylene which provides mechanical protection. 3LPE Coatings provide excellent pipeline protection for small and large diameter pipelines with moderate to high operating temperatures whereas 3LPP Coatings not only provide the toughest, and the most durable pipe coating solution but also provide excellent pipeline protection for small and large diameter pipelines with high operating temperatures. Stainless Steel Pipes can also be supplied with external 3LPE / 3LPP Coating.
External Single Layer/Dual Layer Fusion Bonded Epoxy [FBE / DFBE] Coating
Ratnamani's SFBEis a single layer anti-corrosion coating which is consisting of a high-performance fusion bonded epoxy layer that provides excellent protection in moderate operating temperatures. FBE is a layer of anti-corrosion coating followed by an abrasion-resistant overcoat which provides excellent results for pipes being used under abrasive conditions.
External Coal Tar Enamel [CTE] Coating
Ratnamani's CTE plant is designed to apply a suitable Coal Tar Enamel [CTE] on the external pipe surface as per AWWA, BS or customer specified coating specifications. This CTE coating plant is used for corrosion & mechanical protection of Oil, Gas and Water Pipelines.
External Coal Tar Tape Coating
Coal Tar Tape is applied in cold conditions on the external pipe surface as per AWWA, BS or customer specified coating specifications. This tape coating system is used for corrosion & mechanical protection of Water Pipelines.
External Painting
Ratnamani does various types of External Painting for corrosion protection and insulation properties which can be applied by brush, roller or paint sprayer.
External Cement Mortar Lining
At Ratnamani mixed mortar is projected against the steel surface of the pipe while wire reinforcement is placed throughout the pipe surface as per the customer's specification to add strength. Once completed, water is sprayed as per the curing procedure and customer specification for guaranteed strength and protection. External Cement Mortar Lining is not only durable and inexpensive but protects buried steel pipe for long term service.
INTERNAL COATING SOLUTIONS
Internal Liquid Epoxy
Ratnamani's internal liquid coating plant is designed to apply a suitable spray coating, primer, or epoxy to the abrasively cleaned internal surface of the pipe. Internal Liquid Epoxy coating can be thin-film epoxy, 100% solids, two-component, solvent-free, high build epoxy lining applied to smoothen the internal pipe surface for improved flow and used to provide corrosion protection for the internals of steel pipes. This results in the reduction of friction and increases flow efficiency.
Internal Cement Mortar Lining
Internal Cement Mortar Lining plant is designed to apply a suitable Cement Mortar Lining on the internal pipe surface, as per AWWA coating specifications. Typically used for transportation of water or sewage.
Internal cement mortar lining is performed by use of a spinning machine, which rotates the pipe causing centrifugal pressure on cement mortar which helps in equalizing the mortar thickness and forming a smooth, dense protective lining. Once completed, water is sprayed and ends are capped as per the curing procedure and customer specification for guaranteed strength and protection.
