Both PE pipes and HDPE pipes are called high-density polyethylene pipes. PE pipes include high-density polyethylene PE pipes and medium-density polyethylene PE pipes, so PE pipes include HDPE pipes.

PE pipe and HDPE pipe are pipes of the same material, but they are used in different ways in the production and processing process to form two different shapes and different purposes of pipes. The usual production methods for PE pipes are by slurry or gas phase processing. The commonly used processing methods of HDPE pipes include hydroforming. Hydroforming is to use the hydraulic pressure in the tube blank to expand and then compress the pipe to form a bellows.

The shape of the PE pipe is a smooth straight wall. There are four solid blue or green lines around the pipe body. The outer wall of the HDPE double-wall corrugated pipe is in the form of a ring-shaped spiral, and the inner wall is in the form of a smooth straight wall. The contact surface of the corrugated pipe in this form with the soil is wider and the pressure of the external load on the soil and above is larger. HDPE double-wall corrugated pipe Now it is mainly used for drainage and sewage pipes of municipal, community and rural pipe networks.

Although both PE pipes and HDPE pipes can be used as drainage pipes, the connection methods of the two are indeed different. The connection method we use for PE pipes is the hot-melt connection method, and the connection method for HDPE double-wall corrugated pipes is adopted. It is the connection method of the rubber ring socket. The two are generally not used together.
