3 Design 3.1 General 3.1.1 The design and thickness of the Tarec TM pir thermal insulation for pipework, vessels and equipment equipment operating at cryogenic, low or dual service temperatures shall be to provide: l prevention of condensation on the external surface of the insulation; l temperature control of processes in pipework and equipment; l personnel protection; and l sound control. 3.1.2 As an alternative to the prevention of condensation on the external surface of the insulation, the insulation thickness can be increased on the basis of improved heat gain limits, which will yield higher levels of insulation. The insulation thickness required for the prevention of condensation on the external surface of the insulation and improved heat gain limits or the control of process temperatures, will normally exceed the required thickness for plant safety and personnel protection. For determination of the thickness of insulation required for the prevention of condensation on the outer surface of the insulation refer to Appendices C1 & C2. For determination of the thickness of insulation required for improved heat gain limits and control of process temperatures calculated for typical design and external ambient conditions refer to Appendices C3 & C4. Insulation thicknesses for ambient conditions not indicated in the Appendices need to be calculated by the Kingspan Technical Service Department. 3.1.3 It is essential that moisture does not penetrate the insulation system. Moisture in the form of water vapour, liquid or ice reduces the thermal and structural properties of all insulation materials and will eventually lead to the corrosion of unprotected underlying metal surfaces. 3.1.4 Cryogenic and low temperature insulation of thickness 50 mm / 2 or greater on pipework, equipment and fittings shall be applied with staggered joints. The number of joints shall be kept to a minimum. The minimum thickness of any layer in a multi layered system shall be no less than 25 mm / 1. 3.1.5 A primary vapour barrier shall be applied to the external surface of the Tarec TM pir Process Insulation System. 3.1.6 A factory applied secondary vapour barrier shall be applied to the inner layer of a double layered system and to the intermediate layer of a triple layered system respectively. The secondary vapour barrier shall be a factory applied Triplex Foil Vapour Barrier Jacket sealed with self adhesive Triplex Foil Vapour Barrier Tape. 3.1.7 Vapour stops shall be provided at each termination or interruption in the continuity of the insulation and vapour barrier. Vapour stops shall be installed at each side of all fittings, flanges, valves and supports at the lowermost point of vertical pipework greater than 4 m / 13 in length and other components. For detailed drawings refer to Appendices D20 & D21. 3.1.8 The design of contraction joints and their positions shall be based upon the expected differential contraction between pipework or equipment and insulant as a result of extreme temperatures. For dimensions refer to Appendix C7. For detailed drawings refer to Appendices D12 & D13. 3.1.9 Steel / aluminium cladding, if used, shall be installed and secured in such a manner so that the underlying insulation and the primary vapour barrier as specified in the CINI Specification is not damaged. 5
