Underground Pre-Insulated Pipe
Underground Pre-Insulated Pipe
(OP)
I am helping an engineer design an underground hot/chilled water distribution system and am looking for as much useful help as possible. We are looking at a pre-insulated pipe design with either FRP or PVC casing and Steel or Ductile Iron pipe vs. HDPE casing and Steel or Ductile Iron pipe. What are the benefits/detriments of either of these casing designs. Pipe sizes range from 24" down to 8". Any thoughts or experiences would be greatly appreciated. Thanks!

As mentioned above why not go directly for PE pipe. You obviously need to consider the strength at elevated temperature of any plastic (including fibreglass) pipe.

The grade of ABS used is not that used in the USA that caused all those problems years ago.
This resin has been used in Australia and the Far East for nearly forty years on pressure pipe up to DN 800.
For chilled water it is great as it doesnt have the problem of corrosion under the insulation as steel does. Reduces the need for chemical treatment.
I am designing a major complex in Dubai at the moment using this material. Have used straight ABS for the last thirty years in sewage treatment plants and mineral processing. Its as tough as nails and easier than steeel to assemble.
