Differences Between PE Pipe And PVC Pipe

1. The difference between PE pipe and PVC pipe in transportation safety

Both PE material and PVC material are non-toxic and tasteless. After production and processing, the pipeline is strictly tested to ensure its transportation safety. In terms of materials, both are excellent choices for water pipelines.

2. Performance of resilience

The modulus of elasticity of PE pipe is usually lower than that of PVC pipe, and its toughness will be better, but the toughness is excessive but the rigidity is lacking. In the field of building water supply, the straightness is not good, and it is easy to deform, which causes the pipeline to be unsightly. Therefore, PVC pipes are often used to ensure the straightness and beauty of the pipes.

The toughness of PVC pipe is relatively poor, and it has strong rigidity. In installation, transportation and use, it is fragile and has a low expansion coefficient. Therefore, PE pipes are usually used in gas transportation.

3. The difference in thermal conductivity

The density of PE pipe is higher than that of PVC, and its thermal conductivity is about twice that of PVC. Therefore, it is more suitable for laying floor heating pipes in decoration. The thermal conductivity of PVC is poor, and it can maintain the temperature better in the transportation of solar water heater hot water.

Conclusion: Both PE pipes and PVC pipes are suitable for water supply pipes, but due to the different materials and properties of the pipes, the application fields of the two are different. In terms of price, PE pipes of the same specifications are about 30% more expensive than PVC, but some areas of PE pipes are not available for PVC. Similarly, PVC also has its own unique application areas.
