Hdpe And Pvc Pipe Tech Tuesday Youtube This tech tuesday timmy tipton reviews similarities and differences of hdpe and pvc plus, how they stack up against traditional piping materials. Hdpe pipes have a higher coefficient of thermal expansion (cte) than pvc pipes. the cte of hdpe ranges from 100 to 220 (x 10^ ( 6)) °c, while the cte of pvc ranges from 50 to 110 (x 10^ ( 6)) °c. this means that hdpe pipes expand and contract more with temperature changes, which may increase stress on pipe joints and fittings.
What Are The Differences Between Pvc And Hdpe Petron Thermoplast Pvc and hdpe pipe are inarguably the two most popular pipes used in underground construction and in this article we will compare pvc vs hdpe pipe. in a trenchless technology survey published in our august issue in 2008, we polled sewer system operators and consulting engineers from around the united states about their pipe choices. Generally, hdpe is more cost effective than pvc, especially for larger projects. hdpe pipes, for example, are often more affordable than pvc pipes of the same size and pressure rating. however, the cost difference may vary depending on factors such as the region, availability, and specific application requirements. Pvc is a fairly durable vinyl polymer while hdpe is a thermoplastic made from petroleum. they are both considered plastics. when comparing failure ratings, pvc has shown to be higher than hdpe. pvc has a rating of one in 48,650 events compared to hpde with one in 10,000,000. these failure events included rain stress, wind, heat or cold. Hdpe pipes expand four times more than pvc pipes. hdpe pipes have a lower thermal conductivity than pvc pipes, making them more heat transfer resistant. the thermal conductivity of hdpe ranges from 0.42 to 0.51 w m·k, while pvc’s conductivity ranges from 0.14 to 0.28 w m·k.

Hdpe pipes expand four times more than pvc pipes. hdpe pipes have a lower thermal conductivity than pvc pipes, making them more heat transfer resistant. the thermal conductivity of hdpe ranges from 0.42 to 0.51 w m·k, while pvc’s conductivity ranges from 0.14 to 0.28 w m·k. With hdpe, the pipe can withstand twice the pressure class. in addition, pvc can handle 5.5 feet per second of flow rate before changing its water pressure rating, while hdpe can handle 14 feet per second. overall, hdpe is 2,500 more resistant to cracking and failure due to water hammer and fatigue. pvc has a higher pressure class for static. However, hdpe is able to withstand and dampen more shock waves than pvc. another of the advantages of hdpe pipes is that when covering fiber builds, hdpe works best for many reasons: hdpe can handle season stress (heat and cold). low temperature impact. hdpe can withstand 20 years or more of the sun’s uv rays, while pvc may not last three years.
