The sleeves shall be suitable for 3LPE/FBE coated pipes operating up to 60°C continuously. 3.1.1 Each Joint Coating System shall consist of : a) A wraparound heat shrinkable sleeve reinforced with fibre-glass. The sleeve shall be coated with a higher- shear- strength thermoplastic hot-melt adhesive. b) A solvent-free, two component liquid epoxy primer c) A specifically designed wear cone d) A clamping belt 3.1.2 Sleeve Backing The heat shrinkable sleeves shall be manufactured from minimum 1.0 mm thick radiation cross linked, thermally stabilized, UV -resistant heatshrinkable fabric, composed of a fibre glass reinforcement and polyolefin fibres, embedded in a polyolefin matrix. \\Akjha\work contrac\standard TS for Pipe Line WC (Vol-II) MASTER FOLDER\74 field joint for HDD crossing\Specification for FPJ Coating for HDD Crossing - 074-f.doc Page 2 of 14
3.1.3 Sleeve Adhesive The inner surface of the sleeves shall be coated with a controlled thickness of minimum 1mm of adhesive which in combination with the modified epoxy primer, will bond to and seal to the steel pipe and common yard applied medium temperature yard coatings. 3.1.4 Epoxy Primer The Epoxy primer shall be a solvent free, modified two components liquid epoxy type primer, which is applied to cleaned and dry steel surface. When the sleeve coatings, comes in contact with the liquid primer during installation, a strong bond is formed upon full curing of the system. 3.2 Properties of Field Joint Coating Material The pipe sleeves furnished under this specification shall be tested and shall meet the requirements specified in the table below:- 3.2.1 Heat-Shrinkable Sleeve Material Property Test Method Condition Requirement Cold Crack ISO 4675 Below 40°C Chemical resistance Followed by test for bursting strength Thermal ageing Followed by test for bursting strength 3.2.2 Adhesive material ISO 175 168 hrs. immersion on either 0.1 N NaCl @ 23°C, 0.1N H2 SO4 @ ISO 3303 23°C, 0.1 N NaOH @ 23°C, Fuel oil @ 23°C.
