This standard covers the requirement for supply and application of materials for THERMAL INSULATION of equipment, piping and other items.

4 REFERENCE STANDARDS. IS 14164 Code of Practice for Industrial Application and finishing of THERMAL INSULATION material at temperature -800C and up to 7500C. IS 737 Wrought aluminimum and aluminium alloys, sheet, strip IS 1254 SPECIFICATION for corrugated aluminum sheet TS 6701 THERMAL INSULATION Hot service TS 6702 THERMAL INSULATION Cold service ASTM C-680 Standard Practice for Heat Loss or Gain and Surface Temp. Deviations: Should unforeseen difficulties arise to comply with requirements of this standard. Alternative material and application techniques superior to the requirements of this standard be submitted with complete details for approval of owner.

5 In case of contradiction between requirements of this standard and the NIT/Work order, the later will be followed. LIMITATIONS. Temperature Limits. This standard deals with INSULATION applied externally on piping equipments etc. as per the table below:- Maximum Operating Type of Temperature INSULATION 600C to 7500C for , & HOT. - 1800C to 200C COLD. THICKNESS DESIGN BASIS. Thickness calculation method as per procedure given in ASTM C-680. 1. Hot INSULATION Design Ambient Temperature : 35 C. Design Surface Temperature : 600C.

6 Permissible Heat Loss : 150 hr. FORM NO: 02-0000-0021F3 REV2 All rights reserved TECHNICAL SPECIFICATION PC65-TS-6700 0. THERMAL INSULATION DOCUMENT NO REV. GENERAL REQUIREMENT. SHEET 5 OF 21. Permissible Wind Velocity Outside : 1 m/sec Permissible Wind Velocity Inside : m/sec 2. Cold INSULATION Design Ambient Temperature : 35 C. Design Surface Temperature : 2 C below ambient/ Deg C above the Dew Point Permissible Heat Gain : 10-12 kcal/m2 hr Relative Humidity : 85%. Permissible Wind Velocity Outside : 1 m/sec.

7 Permissible Wind Velocity Inside : m/sec. GENERAL REQUIREMENTS. Information to be supplied to contractor - Material of construction / dimension of equipments / pipes required to be insulated. - Temperature - Location of equipment (Indoor/Outdoor/Elevn.). - Requirement of removable box type INSULATION if any - Special requirements if any regarding type of INSULATION material and other properties. - These information shall be supplied in form of INSULATION schedule. STORAGE OF MATERIAL. INSULATION material shall at no time be stacked directly on the ground; instead it will be stored at a level higher than ground level.

8 It should not only be covered by tarpaulin but other effective protections against weather are also to be provided. The contractor shall provide a properly covered storage to the satisfaction of engineer-in-charge (Refer IS: 10556).. HYDROSTATIC TEST FOR PIPES. Before taking up INSULATION job on piping or vessels it shall be ensured that hydrostatic test of the concerned equipment / piping is completed. Where it is felt necessary to take up the INSULATION job before such testing are performed all welded and mechanical joints shall be left un-insulated for a length of at least 150mm on either side of the joint.

9 PROTECTION OF INCOMPLETE JOBS. Any part of INSULATION job which is not provided with final weather proofing will be adequately protected by means of tarpaulins and other aids. After the day's work similar protection should be provided for the partially completed jobs to be continued the next day to avoid any absorption of rain / moisture during the night. INSULATION SUPPORTS (CLEATS) TO BE PROVIDED BY EQUIPMENT SUPPLIER. Suitable supports (cleats) in the form of rings, lugs, studs or pins shall be provided on equipment by equipment supplier as per Annexure-I, However should any additional supports or anchorage be felt necessary by the INSULATION contractor the same will be recommended by FORM NO: 02-0000-0021F3 REV2 All rights reserved TECHNICAL SPECIFICATION PC65-TS-6700 0.

These will be installed by the contractor free of any extra cost. MATERIAL REQUIREMENTS. INSULATION MATERIALS. General - Whenever reference to any Standard is made it is presumed that the latest revision as on date should be considered unless otherwise specified.. SPECIFICATION and other requirements SPECIFICATION and other requirements will be as per TS-6701 for Hot Service and TS-6702 for Cold Service.
