What are the differences between HDPE pipe and PVC pipe?

One of the first applied plastic pipes developed by pvc pipe is extruded by hot pressing after the use of polyvinyl chloride resin, stabilizers, lubricants, etc. It has good tensile, compressive strength, corrosion resistance and good water tightness.

HDPE pipe is a replacement product of traditional steel pipes and PVC drinking water pipes. HDPE pipe should not only have good economy, but also have a series of advantages such as stable and reliable interface, anti-impact, anti-cracking, anti-aging, and anti-corrosion.

The main difference between HDPE pipe and PVC pipe

PVC pipes and fittings are connected with adhesives, expansion joints, socket joints, etc. HDPE pipe connection adopts butt welding, electric welding pipe hoop connection, sealing ring socket sleeve and thread connection, etc.

Generally, the temperature range of PVC pipes is smaller than that of HDPE pipes. The temperature range of HDPE pipe can reach -60℃～40℃. Because HDPE pipes and fittings are black, they can effectively prevent the influence of ultraviolet rays in the sun on the pipes. Moreover, the wall thickness of the pipe is sufficient to make the socket interface of the sealing ring resistant to 100°C temperature.

What are the differences between HDPE pipe and PVC pipe?

HDPE pipes and fittings are versatile and can be prefabricated and installed, but PVC pipe prefabricated installation is impossible. When the PVC pipe is burning, it will emit harmful fumes. As long as a small amount of PVC combustion exhaust gas is enough to damage the machine and office supplies. The HDPE pipe will not produce harmful gases during combustion. Generally, PVC pipes and fittings have relatively low resistance to external forces, and cracks will occur when the pipes pass through the expansion joints of buildings. According to the Swiss National Organization for the Environment, Forests, and Villages (BUWAL), published data show that from an environmental perspective, the impact of HDPE pipes on the environment from production to final disposal is very small.

This is PVC pipes and HDPE pipes. After reading the above content, we have a general understanding of PVC pipes and HDPE pipes. There are more content about pipes, please continue to pay attention to us.
