26 Coating Process Internal / External Coating With TMK Gulf International Pipe Industry s commitment to deliver highest quality products, corrosion protection is a critical element contributing to the lifespan of steel pipelines. When Carbon steel pipelines are invariably exposed to some type of corrosive environment, a corrosion protection is required which could be as simple as external paint or sophisticated internal and external coatings supplemented by a catholic protection system. Internal: Liquid Epoxy Coating External: Powder Epoxy Coating 24 This application uses a two-part liquid epoxy paint system which is applied in a single coat as anticorrosion for steel pipes. Then liquid epoxy is applied to the pipes inner surface by spray guns in a bogey, forming a uniform single layer epoxy which cures after application. This application uses Fusion Bonded Epoxy (FBE) powder as anticorrosion protection for steel pipes. FBE is a uniform single layer film coating offering good flexibility and excellence resistance to cathodic disbandment. Then the FBE powder is applied to the pipe surface by electrostatic guns, forming a uniform single layer film which cures shortly after application.

27 3 Layer Polyethylene System (3LPE) 3 Layer Polypropylene System (3LPP) 3LPE is a coating system consisting of an inner layer of Fusion Bonded Epoxy, copolymer adhesive layer and outer layer of Polyethylene. Inner layer provide corrosion protection and flexibility while outer layer of Polyethylene provide impact and abrasion protection. The total thickness and combination of various layers used will be in accordance with user specification. 3LPP is similar with 3LPE coating system, the difference is instead of using Polyethylene as an outer layer, and 3LPP uses Polypropylene tape. 3LPP is provided for improved impact and abrasion resistance compared to 3LPE and is suitable with operation temperatures of more than 110 C. 3LPP consists of an inner layer of Fusion Bonded Epoxy, copolymer adhesive layer and outer layer of Polypropylene. Inner layer provide corrosion protection and flexibility while outer layer of Polypropylene provide impact and abrasion protection. 25 The total thickness and combination of various layers used will be in accordance to user specification.

29 Quality Assurance TMK GIPI s Integrated Laboratory is fully equipped with the latest apparatus and technology, including a Optical Spectrometer, High capacity Universal Testing Machine and fully automated DWTT, Charpy Impact Tester, microscope, hardness tester etc. Offering a full range of test and inspection in accordance with API, ASTM, Shell and other international standards, the Laboratory can perform independent metallurgical, mechanical and chemical testing in accordance with ISO/IEC The nucleus of the Laboratory is the group of fully trained and experienced technicians and inspectors well versed in the stringent requirements of API Specifications. Non Destructive Tests are carried out via the latest in Ultrasonic Testing technology. An Offline unit is used for 100% weld seam inspection, a 10-probe Full Body unit offering full body lamination verification, and an Online unit for after-weld monitoring to provide added confidence in the integrity of our weld process. Several Portable UT s are also available for spot inspections when and where required. These NDT equipments are operated by qualified technicians. TMK GIPI can perform hydrostatic pressurization tests of up to 7,000 on offshore and high pressure rating pipes. Hydrogen Induced Cracking (HIC) and Sulfide Stress Cracking (SSC) tests to determine corrosion fatigue on pipes intended for Critical Sour Services are likewise performed in-house, as GIPI possess the only NACE-capable HIC Laboratory in the Sultanate of Oman. 27
