PVC and HDPE are undoubtedly the two most favored pipes used for underground construction.
However, there is much more discussion about which pipe is best for homes and businesses to work with piping solutions.
Both pipes have their robustness and weaknesses therefore selecting one can be tough.
These differentiations between PVC pipe and HDPE pipe to helps you to decide which pipe to work with for your plumbing requirements.
PVC and HDPE pipes and fittings are used widely in water piping solutions.
PVC pipe and HDPE pipe have some similar features that make them the preferred choice for a wide range of applications.
Some of features are:
- Made of Plastic
- Lightweight
- Resistant to Corrosion
- Resistant to bacterial and chemical build-up
- Have higher life expectancy than metallic pipes
Comparison between PVC and HDPE pipe fittings
Longevity
PVC is a durable vinyl polymer while HDPE is a polyethylene thermoplastic made from petroleum.
Both pipes are made through high temperatures. When comparing failure ratings when uncover to events such as rain, stress, wind, heat or cold.
HDPE is proven to be more strong. PVC pipe has a rating of one in 48,650 occurrences; HDPE one in 10,000,000 incidents.
Flexible PVC pipe is however more valuable for one-time projects.
Joining of
PVC pipes are joined by using gasket that is one type of seal that holds two pipes together.
HDPE pipes are joined by heat of fusion. Therefore, while PVC pipe joining can be connected underwater, HDPE cannot.
But HDPE pipes can withstand more shock waves than PVC.
Thermal performance
Expansion of pipes causes slow due to Non-stop exposure to hot or cold weather. Whereas four time expand of HDPE pipe.
Installation
PVC can be place in Open Trench and Drop Burial ways.
The set up process is easy and quick; not based on weather conditions, and does not need any particular machinery to install.
Overall PVC Pipe price is quite reasonable.
HDPE pipes can be set in Open Trench, Drop Burial, Directional Bore, and Horizontal Bore ways.
Trained personnel and energy intensive equipment are required for HDPE fittings. HDPE pipe price can be expensive.
Leakage of PVC and HDPE
PVC pipes are robust and tough, so they can be mechanically attached to valves, non-plastic fittings.
A chief disadvantage is the leakage of water through these joints.
Softer and more bendable HDPE pipes give leak free joints to stop water seepage.
Use in irrigation
PVC pipe is widely used for irrigation. However, more people choose HDPE pipe for irrigation systems where digging is difficult.
For golf course irrigation systems, HDPE pipes are best suited.
Application
PVC pipes are most used in domestic application for water piping solution.
They are also used for sewer, drains, irrigation and industrial purposes.
HDPE has more extensive uses for the delivery of natural gas, petroleum and chemicals.
They are also used in water, sanitation and storm sewer systems.
Conclusion
These comprehensive differences will surely help you to choose best pipe according to your requirement.
