CPVC-AL-CPVC – 3 Layer Composite Pipes
Astral Multi Pro pipes are advanced multi-layered CPVC composite pipes which consist of an inner layer of CPVC, a middle layer of butt-welded aluminum, and an outside layer of CPVC. All the layers are bonded with an adhesive, specially formulated to withstand water temperature up to 93°C.
The three-layer construction of a pipe with a middle layer of aluminum provides strength to the pipe construction and reduces expansion and contraction. As these pipes are used in solar applications and are exposed to different weather conditions, the reduction in expansion and contraction keeps the joints intact.
