B - Make sure that your tools are sharp, that adhesives and paint are fresh and that brushes are in good order. C - Never install insulating materials on functioning equipment; make sure that the equipment is not switched back on until at least 36/48 hours after the insulation material has been installed. D - lnsulation material should be protected with a coating of paint or PVC or aluminium material within 48 hours of installation, especially on outdoor equipment. E - Before insulating pipework ,ducts, metal tanks etc. ensure that any rust is treated with an anti-corrosion agent that has been allowed to dry for at least 24/36 hours. F - Make sure that the parts joined by adhesive are joined by pressure and not by pulling. G - Ensure that junction points and critical points like pumps, flanges, fittings and supports are perfectly sealed. H - Never insulate pipework that is too close together; optimum separation distance is at least 3/4 cm. I N S T R U C T I O N M A N U A L HINTS FOR INSULATION WORK 3 10A - Ensure that you are working in the best environmental conditions (check instructions on the adhesive tin or on the technical data sheet). lt is better to use smaller tins to avoid the premature evaporation of the solvents in the adhesive. B - Always use the correct size brushes (depending on the surface to be glued) that have short, stiff bristles. C - Spread the adhesive in the right quantity on the surface to be glued, ensuring that the surface is clean and free from dust, dirt, oils and fats. D - Before joining the surfaces to be glued it is advisable to allow the solvents to evaporate. Remember that the treated surfaces adhere only when the adhesive is no longer “tacky. I N S T R U C T I O N M A N U A L ADVICE FOR WORKING WITH ADHESIVES 4 Do not proceed yet. 11When the pipe ends are free and not yet assembled, the insulation material can be threaded over the pipe, this applies also to curved sections (fig. 1). NB. This application works subject to the following limitations: for insulation material with a thickness 6-9-13 mm up to a diameter of 1 and 1/4” (42-43 mm), for insulation material with a thickness of 19 mm up to 3/4” (27/28 mm). For large wall thickness insulation material or pipes with a larger diameter than those above proceed using the method detailed in figs. 2 and 3. NOTE: For best insulation practice it is advisable to glue the ends of the insulation material (figs. 4 and 4b). I N S T R U C T I O N M A N U A L 5.1INSULATING PIPEWORK 12A - Wrap a strip of the insulation sheet to be applied around the pipe (fig. 4c) and mark the circumference. B - Copy the mark on the material and cut (fig. 4d) C - Glue the parts to be joined (fig. 4e). D - lnsulate the pipe (fig. 4f). I N S T R U C T I O N M A N U A L STRAIGHT PIPES WITH A DIAMETER ABOVE 160 mm INSULATING PIPEWORK 13ELBOWS Proceed as indicated in figs. 5a,b,c,d. A - Make a 45° cut in the tube to produce two sections B - Join the two parts C - Cut lengthwise D - Thread onto the pipe and glue the cut edges I N S T R U C T I O N M A N U A L 5.2 INSULATING BENDS - ELBOWS 14STANDARD BENDS (DIMA 3) A - Cut the insulation tube into 3, 4 or 5 sections as indicated (fig. 6a). B - Glue the various sections (fig. 6b). C - Cut the joined piece lengthwise, slide onto the curved pipe and glue the cut edges (fig. 6c). I N S T R U C T I O N M A N U A L INSULATING BENDS - ELBOWS 15LARGE RADIUS BENDS (DIMA 5) A - Measure the internal radius of the bend to be insulated (fig. 7a). B - Measure the circumference of the pipe using a piece of tape of the thickness with which the pipe is to be insulated (fig. 7b). C - With chalk, trace the measurements on the insulating material and with a compass draw the bend (fig. 7c). I N S T R U C T I O N M A N U A L INSULATING BENDS - ELBOWS 16D - Cut the first section and then use that as a template for the second and then glue correctly and proceed as in figs. 8a, 8b, 8c, 8d, 8e. I N S T R U C T I O N M A N U A L INSULATING BENDS - ELBOWS 17Proceed as illustrated in the illustrations below (figs. 9a and 9b). Prepare with a suitably sharpened metallic pipe that has the same diameter as the T-pipe to be insulated (fig. 9a). Cut the insulation tube at a 45° angle (two sections of the correct length fig. 9b). In both cases join the two sections with glue (fig. 9c). Cut the joined pieces as in fig. 9d and then fit to the T-pipe section (fig. 9e) and glue. I N S T R U C T I O N M A N U A L 5.3INSULATING T-FITTINGS, REDUCERS AND ANGLED PIPEWORK T-FITTINGS 18Next >
