Insulation work on industrial plant – ancilliary work – calculation O9/2008 approved as a current document part 1 part 2 This paper proposes a measurement method for pipes and equipment that are/are to be insulated. It provides an inventory of calculation bases for the measurement of all elements of which the insulation of industrial plant consists including: - Pipes and ducts - Distributors and collectors - Appliances, vessels and columns - Caps and dome ends 2. Rules for carrying out thermal insulation work – hot Under revision – combined with no 3 under review 3. Rules for carrying out thermal insulation work – cold Under revision – combined with no 2 under review 4. Working manual : system for measurement and recording of industrial insulation cladding 02/1995 under review This manual creates a system of measurement for sheet metal preparation and assembly for cladding pipes, fittings, vessels and tanks in industrial installations. 5. Problems with associated with the warranty of specified surface temperatures 09/2008 approved as a current document This paper highlights the problems associated with warranting surface temperatures with theoretical calculations as the surface temperature is dependant on a number of physical parameters that cannot be calculated or estimated with the necessary degree of certainty. 6. High profitability through ecologically based insulation thicknesses 09/2008 approved as a current document This paper shows that if insulation thicknesses are increased beyond the optimum ‘economic thickness’ to meet an ‘ecological’ standard, the pay back period is only marginally increased particularly on larger bore pipework. 7. Heat insulation of refrigerated premises and buildings – technical clauses 09/2008 approved as a current document This paper provides technical clauses that define the heat insulation works of refrigerated premises and buildings. They give instructions concerning the materials and products required and corresponding rules for installation. 8. Principles of cold insulation 09/2008 approved as a current document This paper discusses the prime requirement to minimise risk of moisture entering cold insulation systems and how to achieve this by use of an efficient vapour retarder and closed cell insulation effectively bonded together. 9. Prevention of corrosion on insulation cladding 09/2008 approved as a current document This paper explains the nature of and mechanism for metal corrosion. It considers the relative corrosion risks for the various metal traditionally used for insulation claddings and their fixings and considers strategies to minimise corrosion. 10. Corrosion under insulation: Problems and solutions 09/2008 approved as a current document This paper considers the factors that can cause the corrosion under insulation that can lurk undetected with disastrous consequences. It explains separately how the designer and the insulation contractor can play their part in preventing this. It goes on to give practical guidance for effective insulation work and finally provides pointers to what the operator should consider to control deterioration of the insulation system. 11. Problems of thermal stress in metal reinforcements of large dimensional objects with elevated service temperatures 09/2008 approved as a current document This paper explains the problems caused by the reinforcing stiffeners required on hot large dimensioned ducts particularly found in power stations. The temperature differentials between the inner and outer edges of the stiffeners can lead to cracking of welded seams. It explains the considerations needed to calculate the appropriate insulation thickness to maintain the maximum admissible temperature differentials. 12. Design of cold insulation to prevent formation of condensation 09/2008 approved as a current document The most frequent reason for cold insulation is to prevent condensation on the insulation cladding surface. The paper provides a checklist of the information needed to design effective cold insulation systems whether provided by client or contractor. 13.
