Overall, due to its thermal conductivity, GEOPERFORMX ® is the most efficient geothermal pipe available on the market. The density of the grout injected into the borehole being twice higher than that of the fluid inside the geothermal pipe, stress applied on the outer wall of the pipe is therefore important.
HDPE pipe is a type of flexible plastic pipe used for fluid and gas transfer and is often used to replace ageing concrete or HDPE mains pipelines. Made from the thermoplastic HDPE (high-density polyethylene), its high level of impermeability and strong molecular bond make it suitable for high pressure pipelines. Puhui Pipe manufacturer in China
Welcome to PE & HDPE Pipe Model Guidance for PE Pressure Pipe Systems a unique and comprehensive information tool The PE Pipe Model, developed by the PE100+ Association with inputs from many industry experts, includes the most frequently asked questions and answers (Q&A''s) of all the elements through the pipe system value chain: design, materials, construction, operation & …
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.
