Description / Abstract:

The Standard sets out requirements for macrocomposite pipes consisting of a welded aluminum tube laminated by a melt adhesive to layers of crosslinked polyethylene inside and outside the aluminum tube. The Standard also provides requirements for fittings (connectors) for use with this composite pipe. The pipes considered in this Standard are for use in potable cold- and hot-water supply, central heating, and underfloor heating systems, and are pressure-rated for 1380 kPa (200 psi) at 23°C and/or 860 kPa (125 psi) at 82°C. 

The Standard includes requirements for materials, quality of work, dimensions, thermocycling resistance, sustained pressure performance, delamination resistance, and marking.


(1) In developing the hydrostatic design basis for the pipes, in accordance with CSA Standard B137.0, the fibre stress has been replaced by pressure.

(2) The pressure rating of macrocomposite pipes is sensitive to the thickness of the aluminum metal reinforcing layer. Pipes having the same dimension ratio but different metal reinforcing layer thicknesses will have different pressure ratings. Dimension ratio therefore cannot be used, as with homogeneous walled pipes, for assessing changes in pressure rating with wall thickness variation
