Multilayer Pipes

What is Multilayer pipes?

Multilayer polymer pipes that are made of a combination of metal and polymer are called multilayer pipes. In this type of pipes, which have high strength and impermeability, the inner and outer layers are made of polymer and a metal layer. (Aluminum) is placed between these layers by means of glue.

Pros

Easy installation

PEX uses a “crimp” installation method that involves crimping a ring around a ribbed fitting using a specialized tool. PEX can even be retrofitted to copper or PVC pipes using the crimp method and specialized fittings

Flexibility

PEX piping is conducive to tight spaces and sharp corners and can stretch for long distances without requiring additional fittings.

Cons

Inside use only

Since PEX is susceptible to deterioration from ultraviolet rays, these pipes can’t be used outside.

Discrepancy over safety

Some studies have shown that chemicals within PEX pipes leach into the drinking water, potentially exposing homeowners to carcinogens. As a result, PEX piping is against the plumbing code in the state of California.
