Aluminum-Polypropylene (AL-PP) Composite Piping Systems

IAPMO IGC 239 – Aluminum-Polypropylene (AL-PP) Composite Piping SystemsIAPMO IGC 239-2014 (R2020) covers:

• aluminum-polypropylene (AL-PP) composite pipe consisting of a core of extruded polypropylene (PP) surrounded by a welded aluminum (AL) tube joined by a melt adhesive; and
• fittings intended for use with the AL-PP composite pipe.

Piping systems covered by this Standard are intended for use in residential and commercial:

• hot- and cold-water supply and distribution systems;
• fire protection systems;
• radiant panel heating systems and hydronic baseboard heating systems;
• compressed air distribution systems; and
• gas distribution systems;

and pressure-rated for:

• 1,600 kPA (232 psi) at 23 °C (73 °F);
• 860 kPa (125 psi) at 82 °C (180 °F); or
• both.
