When the rotational shear was performed at 8 rpm, the hoop tensile strength, thermal conductivity in in-plane and heat resistance of the pipes increased by 235.9%, 34.4% and 32.6%, respectively. With the annealed temperature close to 125 °C for 40 min on the pipes, thin-lamella could be melted to the amorphous phase that facilitated the random chains rearrange on thick-kebab.
Thermal Conductivity of HDPE (Atmospheric and 1000 bar Pressures) Repeatability (95% confidence level) of thermal conductivity test data for one operator testing HDPE HCE000 from 170 C to 50 C at 1000 bar pressure (green) and at aient pressure (blue)
HDPE pipe containing 2-3% carbon black is suitable for indefinite long-term surface or above grade use or storage without cover or other measures to protect black product from direct exposure to UV energy.
Its material itself has very low thermal conductivity coefficient, good insulation performance, low smoke, low-toxic and excellent heat-resistance etc. Meanwhile PID double-sided aluminum foil phenolic composites duct inside and outside surface are composite of metal foil composite layer with special craft and phenolic resin, becoming the leading product in field of composite duct.

The first PE pipe material used in engineering appliions was Type 50 High Density PE (HDPE) with a long term stress of 50MPa. Subsequently, Medium Density (MDPE) materials, with improved pipe properties when compared to the earlier high density materials, were used in pipes due to their improved flexibility, ductility, slow crack growth resistance and crack propagation resistance.
