Hepworth PERTII is no crosslinking necessary process as HDPE(PE100) material with good temperature /pressure resistance t for long term service，perform excellent resistance to creep rupture。Good thermal stability under hydrostatic pressure exceeds PE-RT Type II classification (ISO 24033&GB/T28799) .Wall-thickness reduction for Type II, material savings of 14 % in comparison to PE-RT Type I(ISO10508class #2).
Good melt strength and fusion ability , good resistance to stress cracking.
All PERT Hepworth systems use well-established homogeneous welding techniques to join components. The weld becomes the strongest part of the system. Using socket welding ensure the reliability of the whole system.
PERT II flexible pressure piping systems for the growing demand of flexible pipes in surface heating and cooling systems.
PERT II can be used for mono- and multilayer pipe designs containing oxygen barrier layers such as EVOH in heating pipes.
