PP-R pipe, also known as three-propylene polypropylene pipe, random copolymerized polypropylene pipe or PPR pipe, is a pipe made of random copolymerized polypropylene. HDPE pipe is a pipe made of high-density polyethylene (English name is “High Density Polyethylene”, referred to as “HDPE”). HDPE pipe is the replacement product of traditional steel pipe and PVC drinking water pipe.

1. The density is different. The density of HDPE pipe is higher than that of PPR pipe. The former is high-density polyethylene, and the latter is ordinary polyethylene.

2. The price is different: After the quality of HDPE pipes is improved, the scope of use will only increase, but the demand will increase sharply, resulting in price increases. The latter is a relatively normal price due to little change in demand.

3. Various application scenarios: HDPE pipes are of high quality and are suitable for many places with very high performance requirements, and the latter are suitable for general places.
