Clarification of Pipe Insulation

Whilst our blog attempts to give general guidance and we take care not to publish any misleading content, sometimes it is difficult to manage all different standards for the various code classifications across different countries. Our last blog “Why use Thermoplastics” implied that thermal insulation was not required. We have altered the 5th point to say one of the key benefits of thermoplastics is Low thermal conductivity has improved thermal performance over traditional materials. This point was altered as one of blog readers cited standard AS/NZS 3500:4:2003 Table 8.1 Piping connected to storage water heater piping Minimum thermal insulation “R” Value Internal locations 0.3; for external locations :-  Climate Region (A  0.3) (refer to fig 8.1 New South Wales) Climate region (B  0.6) Climate region (C 1.0). Table 8.2 Heated Water Piping has similar requirements, and notes the following(3a) 13 mm of closed cell polymer R= 0.3 (3b) 25 mm of closed cell polymer R=06 (3c) 38 mm closed cell polymer R=1.0 It is understood that the R values relate to water temperatures of 60◦C. From this information we (the reader) are inclined to believe that thermal insulation is at least recommended by AS/NZS 3500, and possibly also other regulation boards. Use of correct pipe insulation can also result reduced energy costs; a desirable advantage. The point we (the writer) were trying to make was to compare thermal conductivity between copper and PP-R for instance. It is great to receive...

Why use Thermoplastics?

This is a wrap of the key benefits of using thermoplastics  1. Corrosion-free No incrustation thanks to smooth internal surface 2. Chemical resistance Good compatibility with chemicals Most economical solution for your requirements 3. Low total cost of installation Reduced pipe sizes Reduced welding times 4. Low material weight Low density – no machinery required to carry material Low anchor forces save installation costs 5. Low thermal conductivity Improved thermal performance over traditional materials No corrosion due to less condensation and higher resistance results in cost savings 6. No electrical conductivity No corrosion No additional earthing...
