Scope

1.1
This Standard covers polyethylene/aluminum/polyethylene (PE-AL-PE) macrocomposite pipe consisting of a welded aluminum tube laminated by a melt adhesive to layers of polyethylene (PE) inside and outside the aluminum tube. The pipes covered in this Standard are pressure rated for 1380 kPa at 23 C, 1035 kPa at 60 C, or 690 kPa at 82 C.

Systems are intended for use in potable water distribution systems or other applications, including municipal water service lines, reclaimed water distribution, radiant panel heating systems, hydronic baseboard heating systems, snow and ice melting systems, building services piping, compressed air distribution, ground source geothermal systems, underground irrigation, and compressed gas distribution (not including fuel gases), provided that the PE-AL-PE systems comply with the applicable code requirements. Residential and commercial systems are included.

Note: The complete structure, consisting of the aluminum, melt adhesive, and layers of PE intimately bonded together, is known as pipe. For the purposes of this Standard, the layer of welded aluminum, or the internal or external layer of PE, is known as a tube. Tubes, intimately bonded together by the melt adhesive, form a pipe.

1.2
The Standard specifies requirements for materials, quality of work, dimensions, thermocycling resistance, sustained pressure performance, delamination resistance, and marking.

Notes:

1) In developing the hydrostatic design basis for PE-AL-PE pipes, in accordance with CSA B137.0, pressure has been substituted for fibre stress.

2) The pressure rating of PE-AL-PE pipes is contingent on 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. The dimension ratio therefore cannot be used, as it is with homogeneous walled pipes, to assess changes in pressure rating with wall thickness variation.

This Standard also covers fittings (connectors) for use with PEX-AL-PEX pipe. The pipes covered in this Standard are pressure rated for 1380 kPa at 23 C or 860 kPa at 82 C, or both.

Systems are intended for use in potable water distribution systems or other applications, including municipal water service lines, reclaimed water distribution, radiant panel heating systems, hydronic baseboard heating systems, snow and ice melting systems, building services piping, compressed air distribution, ground source geothermal systems, underground irrigation, and compressed gas distribution (not including fuel gases), provided that the PEX-AL-PEX systems comply with the applicable code requirements. Residential and commercial systems are included.

Note: The complete structure, consisting of the aluminum, melt adhesive, and layers of crosslinked polyethylene intimately bonded together, is known as pipe. For the purposes of this Standard, the layer of welded aluminum, or the internal and external layer of crosslinked polyethylene, is known as a tube. Tubes, intimately bonded together by the melt adhesive, form a pipe.

1.2
This Standard specifies requirements for materials, quality of work, dimensions, thermocycling resistance, sustained pressure performance, delamination resistance, and marking.

Notes:

1) In developing the hydrostatic design basis for PEX-AL-PEX pipes, in accordance with CSA B137.0, pressure has been substituted for fibre stress.

2) The pressure rating of PEX-AL-PEX pipes is contingent on 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. The dimension ratio therefore cannot be used, as it is with homogeneous walled pipes, to assess changes in pressure rating with wall thickness variation.

Notes:

1) In this Standard, "pipe" refers to pipe having NPS (nominal pipe size) outside diameters and "tubing" refers to pipe having NTS (nominal tube size) outside diameters.
