CSA - CAN/CSA-B137.9-98

Polyethylene/Aluminum/Polyethylene Composite Pressure Pipe Systems

inactive
Organization: CSA
Publication Date: 1 January 1998
Status: inactive
Page Count: 26
scope:

The Standard covers 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 covers fittings (connectors) for use with this composite pipe. The pipes covered in this Standard are for use in potable water supply systems and are pressure rated for 1380 kPa (200 psl) at 23°C and/or 1035 kPa (150 psi) at 60°C.

The Standard includes requirements for materials, workmanship, dimensions, thermocycling resistance, sustained pressure performance, dclaminatlon resistance, and marking.

Notes:

(1) In developing the hydrostatic design basis for the pipes, in accordance with CSA Standard CAN3-B137.0, the fibre stress has been replaced by pressure.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 cannot therefore be used, as with homogeneous walled
