Wherever necessary this specification indicates the basis for selecting a criterion, This specification is suitable for use in normal process plant atmospheres. Altemative designs and materials would be specified if necessary for corrosive atmosphere or potential leaks and spills of chemicals. All the codes/standards mentioned in this specification shall be of latest issue, This specification does not cover cold service insulation. For cold services, Specification 6- 44-0003 is applicable. ‘This specification does not cover insulation for boiler or fired heaters and associated air heaters, economizers, flue ducting and air ducting. Piping, equipment, storage tanks & vessels requiring insulation and the temperatures (operating temperatures) shall normally be specified, as applicable, on the following project documents: - Piping and Instrument Diagrams (P&IDs) and Line Lists. : Piping General Arrangement Drawings & Isometries. - Instrument Piping Details and Schedules. : Vessel, Exchanger, Storage Tank and sphere documents and Insulation Schedules. : Equipment suppliers General Arrangement Drawings for equipment items in Package plant. DESIGN BASIS Criteria Insulation thickness tables are based on heat loss criteria.

Unless otherwise specified, all valves and flanged joints shall be completely insulated only in steam, condensate service, hot oil lines and in lines which are trace heated or jacketed to ‘maintain temperatures. For bucket and float type traps the inlet piping and trap shall be insulated. Insulation on inlet piping to thermostatic and thermodynamic steam traps shall terminate at approximately 500mm before the trap. Steam trap outlet piping other than closed condensate recovery system shall not be insulated ‘except for personnel protection reasons. Heat traced instrumentation shall be insulated. The fluid containing sections of such struments and the associated piping shall be completely insulated. Indication length shall remain visible. Instrumentation other than heat traced shall not be insulated unless otherwise required by Instrumentation department. Insulation shall not be applied to the following, unless otherwise specified. : Piping which becomes hot intermittently, such as relief valves, vents, steam-out and snuffing steam systems, flare and blowdown systems. - Steam condensate lines downstream of steam traps discharging to drainage system, unless otherwise mentioned, ~ Supports for piping, excluding pipe hangers to the extent covered by insulation.

The Contractor is responsible for applying an insulating system that will give a satisfactory operational performance and the requirements given herein shall be regarded as the acceptable minimum, The Contractor shall carryout the work in accordance with the best practices of insulation application with the minimum of waste and debris and the final job shall have a neat, efficient and workmanlike appearance. ‘The insulation shall be so designéd/applied such that ingress of water is prevented, leaked product can drain off and vapour can escape. All hydrostatic tests on piping and equipment, including steam tracing systems, shall be carried out before insulating material is applied. ‘The insulation Contractor shall only insulate those sections of the plant that have been specifically released for such work by the engineer-in-charge. If insulation must be installed before pressure test, then all welds and flanged joints in the pipe shall be left uncovered till successful completion of pressure test. Then insulation shall be completed Surfaces to be insulated shall be thoroughly cleaned, dried and made free from loose scale, oil or grease. It shall be the Contractor's responsibility to remove loosely adhering scale and dirt before applying insulation.

The flats are for insulation support and holes provided in them are to be used for insulation securement. Also provided on either head is a central ring made of 10 dia galvanized steel rod. For vessels which do not have central nozzle, these rings shall not be provided by vessel fabricator. For such vessels, insulation contractor shall provide these rings. - Boot of vessel, if any, is provided with circular support ring with holes, as indicated in sketch. 2 Blanket shall be applied over the surface with joints tightly butted and laced together with Imm dia galvanized lacing wire Other block insulation shall be applied with the longer dimension parallel to the axis of the vessel or equipment. When blocks are applied in multiple layers, all joints in successive layers shall be parallel to the long axis, shall be staggered and sealed with insulating cement for calcium silicate or suitable adhesive for others. In all cases, the insulation is to fit the contour of the vessel or equipment, so that the use of a leveling coat of insulating cement should not be normally necessary to get an acceptable smooth exterior. 3 Special considerations for insulating high temperature Vessels (Required only if provided with calcium silicate insulation) (Fig. 15) This provision is required to take care of the effects of equipment circumferential thermal expansion on insulation, This provision is required only for vessels and Exchangers provided with calcium silicate insulation. Calcium silicate insulation should be installed in bevelled or curved segments only, to avoid voids and provide an efficient insulation system, For equipments upto 3000mm in diameter and 200°C, to take care of equipment circumferential expansion, the circumferential block is-cut and fitted to be 13mm greater in circumference than the equipment and secured so that tension of the bands produces compression on the butt edges rather than on the surface towards the vessel; the little annular space and the compressiveness of the blocks would suffice to take care of circumferential expansion of equipment. If the vessel is above 3000mm in diameter or if temperature is above 200°C or both, a 25mm thick Rockwool fibre blanket insulation shall be applied around the equipment prior to the application of calcium silicate. This acts as an expansion area around the ‘equipment to act as mechanical and sometimes thermal cushions. The calcium silicate block must be cut and fitted to the outside radius of the equipment plus the thickness of the Rockwool spacer insulation. The insulation, when installed, should not compress the fibrous blanket. Above provision to take care of circumferential expansion is required both for shell and head. 4.3.3 Insulation Securement (for all insulation materials) (Refer Fig-13 and 14) Each layer of insulation on shells of equipment shall be secured by bands at every 225 centres.
