Corrosion Resistant Linings | Rotolining | Polymer Coating

Extend the life of your assets with polymer lining inside steel vessels, pipes, and fittings. Polymer lining protects your assets from acids, alkalis, oxidizers & solvents by applying a layer of polyethylene enriched with corrosion-resistant chemicals.<br><br>What makes a polymer lining stand out from other linings is that its lining process forms a protective layer of 2-11 mm thickness which is maximum compared to all other linings.

  3. General Profile 3

  4. General Profile Al Nasser Industrial Enterpises LLC (ANIE) ANIE was established in 1993 by Al Nasser Holdings LLC to promote profitable industrial ventures and establish a presence in the GCC region. Over the following three decades, the goals and strategies initially envisioned have been translated into remarkable achievements resulting in tremendous growth in the manufacturing sector and firmly establishing ANIE as a noteworthy private sector leader. ANIE is, today, one of the leading industrial holding companies in the UAE, and is poised for further growth. 4

  5. General Profile Polycon Gulf Ltd is part of Al Nasser Industrial Enterprises (ANIE). The company was established in 1991 to manufacture a wide range of polyethylene water & chemical storage tanks. It was the first of its kind in the GCC. 5

  6. General Profile ØGuiding Principles: v Be First to Bring Value for Money to the Customer v No compromise on Quality & Service 6

  7. General Profile PRODUCT RANGE Water Tanks • Vertical / Horizontal / Under Ground Tank • Standard 3 layers / insulated 4 layers • Size 35 to 10,000 USG Road Barriers & Track Barriers Portable Rest Rooms Customized Products For Security • Defense Bunkers • Marine Buoys and Pontoons Sewage Manholes, Branching Garbage Bins Illuminated Planters Pallets 7

  9. CONTENT 1. Polyethylene Lining – Introduction 2. The Process 3. Benefits and Comparisons 4. Applications and Market Segments 9

  10. POLYETHYLENE (ROTO) LINING What is Polyethylene / Roto Lining ? Roto lining is a technique that allows a chemically modified polyethylene & various materials to bond with metals to line metal vessels, chemical storage tanks, carbon steel pipes and fittings. The rotational molding process allows a seamless lining of 2 - 8 mm thick to the interior surfaces of the carbon steel pipes, fittings and vessels. 10

  11. BENEFITS OF ROTO LINING Ø Excellent Resistance to Corrosion from v Acids , Alkalies and Salts Ø Seamless / Joint free Lining Ø Easier to Line Complex Shapes Ø Thicker Lining & Uniform wall thickness Ø Fast processing time Ø Longer ‘Life-Cycle’ compared to other lining Ø Process controls by sophisticated PLC 11

  12. APPLICATIONS Ø Saline Water Handling Systems v Oil & Gas Sector v Ballast Water v Water Based Fire Fighting Systems v Water Treatment Plants Ø Chemicals Sector v Acid Tanker & Vessels v Reactors & Receivers v Transmission lines Ø Critical Spares Replacement …. 12

  13. INDUSTRIES Ø Oil & Gas Industries Ø Petrochemicals & Chemical Transport Ø Ship Building & Ship Maintenance Ø Water Treatment & Water Handling Ø Thermal Power Plants Ø MEP and Maintenance Contractors Ø Fertilizers Ø And many more. 13

  14. THE PROCESS 1. 2. 3. 4. 5. 6. Pre Lining Inspection Preparation Molding Process Finishing Final Inspection & Testing Packing & Delivery 14

  15. Pre Lining Inspection Visual Inspection: All welding joints should be properly grounded and should be free from any burrs. The inside surface of spools should be free from dust/grease/oily residue or any foreign materials 15

  16. Preparation Grit Blasting: Coarse Grit blasting is done using Steel Grit, for better adhesion on internal surface as per ISO standard 16

  17. Preparation Surface Profile : Surface profile test after grit blasting is carried out as per ASTM Standard Salt Contamination Test: Is carried out as per SSPC Guideline prior to starting lining. 17

  18. Molding Process • Carried out using a highly sophisticated machine with finest process monitoring & controls • Each article requires different preparation procedure and different processing. Roto lining process ensures an excellent plastic to metal bonding. 18

  19. Finishing 19

  20. Final Product Inspection & Testing Thickness Test (ASTM Standard) Hammer Test Spark Test: 100% holiday testing or spark testing is performed to insure liner integrity. Spark test is performed with 15 KV DC. 20

  21. Final Product Inspection & Testing Adhesion Test: Adhesion test is conducted on different samples. Lining sample is done on flat sheet. Mechanical Properties Test: Tensile test Compressive Hardness Izod Impact as per ASTM standard 21
