Job title................................................................................................................ Organisation...................................................................................................... 1.Which of these were not specifically mentioned as a driver for the development of multilayered pipe? A Existing plastic pipes were not recyclable B Oxygen diffuses through plastic C Plastic pipes were unable to hold visually acceptable straight pipe runs D Plastic pipes can curl due to shape memory E Plastic pipes required extensive fixing 2.What is the surface roughness of the example PE-RT Al PE-RT multilayer pipe? A 2m B 7m C 12m D 17m E 22m 3.What operating pressure is associated with multilayer pipe in the article? A 1bar B 10bar C 30bar D 60bar E 100bar 4.Which of these is unlikely to be true for current multilayer pipework system technology? A Bends in smaller sizes can be formed by hand without collapsing the tube B Cutting pipe and connections in these systems is clean, with no consumables C Fittings are probably made of materials including plastic, stainless steel and brass D It is WRAS-approved for use in drinking-water installations E They provide a flexible and adaptable method of Address .............................................................................................................. ............................................................................................................................... ...............................................................................................................................

CIBSE Guide section B1 considers heating systems, including pipework design and expansion (Appendix A1.5). CIBSE AM14:2010 section 4.3.7 gives an introduction on thermal expansion of pipework. BSRIA Guide 30/2007 (Section W) provides one of the most complete references for practically sizing basic pipework systems.

A 1% the expansion of simple (single-layer) PE-RT pipe B 5% the expansion of simple (single-layer) PE-RT pipe C 10% the expansion of simple (single-layer) PE-RT pipe D 50% the expansion of simple (single-layer) PE-RT pipe E Almost the same expansion as a simple (single-layer) PE-RT pipe 50 May 2020 www.cibsejournal.com CIBSE May 20 pp47-50 CPD Geberit v2.indd 50 24/04/2020 16:35
