What is the difference between PE pipe and HDPE pipe

2023-04-23 16:29

PE pipe and HDPE pipe are both common pipes, and many people may not be able to distinguish the difference between the two. Now let's take a look together.
PE pipe is a polyethylene plastic pipe, and PE is the most basic type of plastic with excellent resistance to most household and industrial chemicals. PE pipes can be divided into low-density polyethylene pipes, medium density polyethylene pipes, and high-density polyethylene pipes.
HDPE pipe belongs to the high-density polyethylene pipe in PE pipes, and the material is "HDPE". HDPE is a thermoplastic resin with high crystallinity and non polarity. The appearance of HDPE in its original state is milky white, with a certain degree of translucency on its thin cross-section.
That is to say, HDPE pipe is a type of PE pipe, but compared to ordinary PE pipes, HDPE pipe has superior performance and a wider range of applications.
The main manifestations are as follows:
1. HDPE pipes must withstand a certain amount of pressure, usually using PE resin with high molecular weight and good mechanical properties, such as HDPE resin, which has a strength 9 times that of ordinary polyethylene pipes (PE pipes).
2. Among all engineering plastics, HDPE ranks first in terms of wear resistance. The higher the molecular weight, the more wear-resistant the material becomes, even surpassing many metal materials (such as carbon steel, stainless steel, bronze, etc.), which ordinary PE does not possess.
3. HDPE pipes are a replacement product of traditional steel pipes and polyvinyl chloride drinking water pipes, while ordinary PE pipes are not suitable.
4. General PE pipes (medium density polyethylene pipes) are suitable for conveying gaseous artificial gas, natural gas, and liquefied petroleum gas. Low density polyethylene pipes are flexible hoses, while HDPE pipes (high density polyethylene pipes) are mainly used for conveying natural gas, municipal engineering water supply systems, indoor water supply systems in buildings, outdoor buried water supply systems, as well as underground water supply systems in residential and factory areas. Old pipeline repairs, water treatment engineering pipeline systems, gardens Industrial water pipes for irrigation and other fields.
