PP-R pipe and PE pipe are two commonly used plastic pipes. They have a wide range of applications, but their performance differences are still relatively large. Let’s analyze their performance differences in detail below.IFAN factory 30+ years manufacture experience support color /size customization support free sample.Welcome to consult for catalog and free samples.This is our Instagram Website: www.instagram.com
1. Heat-meltability:
PP-R pipes are more suitable for heat welding than PE pipes, because the heat deformation temperature of PP-R pipes is higher than that of PE pipes, and the joint strength after heat welding is higher.
2. Temperature resistance:
PP-R pipes have higher temperature resistance than PE pipes. PP-R pipes can withstand high temperatures of 70°C at room temperature and 100°C under short-term loads, while PE pipes can only withstand 60°C Therefore, in high temperature environments, PP-R pipes are more widely used.
3. Corrosion resistance:
PP-R pipes have better corrosion resistance than PE pipes. PP-R pipes have strong chemical stability and can resist most chemical corrosion, while PE pipes have poor resistance to chemical substances. , susceptible to corrosion.
4. Compression resistance:
The compression resistance of PE pipes is better than that of PP-R pipes. The linear density of PE pipes is higher, so its impact resistance and impact strength are stronger, and it can withstand greater pressure.
5. Bendability:
PP-R pipes are more suitable for curved pipes than PE pipes, because PP-R pipes are more bendable and can be easily bent during construction.
Generally speaking, PP-R pipes and PE pipes have their own advantages. In actual use, appropriate pipes should be selected according to actual needs. If it is used in a high temperature environment and there is a risk of corrosion, you can consider using PP-R pipes; if you require stronger pressure resistance, you can choose PE pipes.
