What is the difference between HDPE pipe and PVC pipe?

An application of plastic pipe, which was first developed by pvc pipe, is formed by using a polyvinyl chloride resin, a stabilizer, a lubricant, etc., and then extruding it by hot pressing. It has good tensile strength, compressive strength, corrosion resistance and good water tightness.

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

The main difference between HDPE pipe and PVC pipe

Connection of PVC pipes and fittings or use of adhesives or expansion joints, socket joints, etc. The HDPE pipe connection uses butt welding, electric welded pipe hoop connection, sealing ring socket sleeve and threaded connection.

Generally, the temperature range of PVC pipe is smaller than that of HDPE pipe. The temperature range of HDPE pipe can reach -60 °C ~ 40 °C. Since the HDPE tube and fittings are black, it can effectively prevent the influence of ultraviolet rays in the sunlight on the tube. Moreover, sufficient wall thickness allows the seal socket socket to withstand temperatures of 100 °C.

HDPE pipes and fittings are versatile and can be prefabricated, but PVC pipe prefabrication is not possible. PVC pipes emit harmful fumes when burned, as long as a small amount of PVC combustion exhaust gas is enough to damage machinery and office supplies. HDPE pipes do not generate harmful gases during combustion. Generally, PVC pipes and fittings have relatively low resistance to external forces, and cracks may occur when pipes pass through expansion joints of buildings. According to the Swiss National Environment, Forests and Rural Organization (BUWAL), published data show that from an environmental point of view, the environmental impact of HDPE pipes from production to final processing is small.

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