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.
Core pipe shall be rigid HDPE PE100, in accordance with ISO 4427/DIN 8074/8075. Thermal insulation is made of 100% CFC free polyurethane foam; having a minimum density of 48 kg/m3 and thermal conductivity coefficient (λ) in the range of to W/mK.

HDPE is known for its high strength to density ratio. The density of HDPE can range from 930 to 970 kg/m 3. Although the density of HDPE is only marginally higher than that of low density polyethylene, HDPE has little branching, giving it stronger intermolecular forces and
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.
