Description
PEX Pipe, made of crosslinked polyethylene (PE-X), is designed to convey pressurized fluids at operating temperatures of up to 95 °C. Its crosslinked molecular structure combines the mechanical strength of polyethylene with exceptional thermal stability, allowing its use in applications where conventional plastic pipe reaches its limits. It offers excellent resistance to slow crack growth (SCG), high flexibility and high durability, even when buried in unprepared trenches or with stony backfill. Its low friction coefficient ensures efficient flow, reducing head loss and pumping costs.
Market and applications
- Industry.
- Hot fluid transport systems.
- Industrial thermal networks.
- Heating processes.
- Chemical plants.
- Buried or aboveground installations where high resistance to temperature, abrasion and internal pressure is required.
