What is difference between HDPE and PVC pipes?
PVC is a durable vinyl polymer whereas HDPE is a polyethylene thermoplastic made from petroleum. Both pipes are strong through high temperatures. When comparing failure ratings when exposed to events like rain, stress, wind, heat or cold, HDPE is proven to be more durable.
Why is HDPE pipe used?
HDPE Pipe Uses and Advantages. HDPE pipes are known for its lighter weight as compared to iron or galvanized pipes. These flexible and reliable pipes come with unmatched corrosion and chemical resistance. As HDPE pipes are lightweight, it easy to install and transport.
Which is stronger PVC or HDPE?
HDPE is a softer, more bendable plastic, making HDPE pipe more suitable for lower pressure, tight bending radius situations. On the other hand, PVC is a much stronger and stiffer material, which is why PVC pipes are more widely used for direct burial and trenchless installations.
Who Uses HDPE pipes?
Nuclear power plants and power stations use HDPE to carry water, seawater, chemicals, and safe radioactive drainage and ultimately as effluent pipelines. Power plants commonly use HDPE as a cooling water pipe and ash slurry disposal pipes. Oil refineries carry air, water, and acids in HDPE pipelines.
Is HDPE pipe the same as PEX?
High-Density Polyethylene (HDPE) pipe has been used for decades in non-potable water applications. Suppliers then developed cross-linked polyethylene (PEX) with superior strength and high temperature performance. PEX is common in radiant floor heating applications and, increasingly, in domestic hot/cold water systems.
What is the life expectancy of HDPE pipe?
High-density Polyethylene (HDPE) Pipes Estimated life span – 50 to 100 years HDPE pipes are manufactured by the extrusion technique on a single screw extruder. HDPE granules are melted and cast in dies.
What does HDPE pipe stand for?
The acronym HDPE stands for high density polyethylene .. The substance is used in bags, bottles and other household products, as well as in piping systems. HDPE is known for its tensile strength and ability to withstand high temperatures.
What are the usage characteristics of HDPE pipe?
It takes less energy to manufacture HDPE than non-plastic pipes.
What is the difference between PVC and HDPE?
The key difference between HDPE and PVC is the difference in density; HDPE is denser than PVC, and this leads to differences in their physical properties and industrial applications. In addition, the difference in chemical structure and manufacturing process also give them some unique material properties.
