CSA - CAN/CSA-B137.9-M91

Polyethylene/Aluminum/Polyethylene Composite Pressure Pipe Systems

inactive
Organization: CSA
Publication Date: 1 April 1991
Status: inactive
Page Count: 32
scope:

The Standard sets out requirements for macrocomposite pipes consisting of a welded aluminum tube laminated by a melt adhesive to layers of 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 water supply systems and are pressure rated for 1380 kPa (200 psi) at 23°C and/or 1035 kPa (150 psi) at 60°C.

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

Notes:

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In developing the hydrostatic design bosh for the pipes, in accordance with CSA Standard B137.0, the fibre stress has been replaced by pressure.

(2) The pressure rating of mocrocomposite pipes is sensitive to the thickness of the ok/minum metal reinforcing layer. Pipes having the same dimension ratio bat different metal reinforcing layer thicknesses wn'l have different pressure rotings. Dimension ratio therefore cannot be used, os with homogeneous availed pipes, for assessing changes in pressure rating with wall thickness variation
