PIPE SUPPORTS & STEEL WORK 1. In situations where there are piping load bearing supports and steel work clash, and the complete specified insulation thickness cannot be implemented, due to space restrictions, the insulation layer shall, where applicable, be cut around the steel leg support. The cut outs shall be neat/tidy and accurate with no gaps present. 2. The cut out details shall be sealed at all times with Armaflex Adhesive / Arma-Chek mastic. 3. Where applicable and required, for optimum performance, in order to avoid acoustic and thermal bridging, all steel work that is directly attached to the main piping equipment shall be insulated to the same thickness and product combination as indicated within the Clients Project Insulation Specification. In addition, where required valves and flanges can be insulated with the same thickness and material combinations as the connecting pipe. The insulation layers, follow the contours of the equipment. Storage of Armacell products Store in a safe place, following all procedures of the client and Armacell relating to Health + Safety, storage and handling procedures. REFERENCE Armaflex Installation Manual Arma-Chek R - Installation Manual Armaflex Cold Work Application Manual 4. Final system appearance All unwanted Armaflex Adhesive marks and spillages on the final outer Arma-Chek R covering layer shall be easily cleaned away using Armaflex Cleaner applied using a clean cloth. It is recommended that this procedure be followed whilst cleaning the seam and joint details prior to applying the mastic as the final application detail of the insulation system. Note: Ensure the Armaflex Cleaner has dried away, before applying the mastic. This should take 1-3 minutes for the solvents to evaporate depending on the ambient air temperature. INSULATION OF VALVES WITH ARMASOUND INDUSTRIAL SYSTEMS For the acoustic treatment of valves, please refer to the Armacell Installation Processing Specification document where applicable. In addition, where valves and flanges are to be insulated with the same insulation system as the connecting pipe, the insulation layers should follow the contours of the equipment. Armacell - Installation Processing Specification (IPS). Project specific issue. NOTE: In order to gain the maximum performance from both the materials and the acoustic value requirements it is important that a high standard of workmanship is achieved during this type of application. All installers are advised to receive or attended an Armacell Installation Training Course and be certificated / approved before commencing the application process as detailed above. 6 ArmaSound ARMACELL INTERNATIONAL GMBH
