Description

Technical Field

[0001] The utility model belongs to the technical field of pipe fittings, and in particular relates to a PE composite pipeline structure. Background Art

[0002] PE composite pipe refers to two polyethylene resins with different densities, which are plasticized and melted by two extruders at the same time, and then the molten materials are squeezed into a mold that can form a composite pipe. The formed pipe is the PE composite pipe. This composite pipe can be extruded and compounded with a variety of plastics. The pipe composited with high-density polyethylene and low-density polyethylene has the characteristics of both raw materials. Its pressure resistance and corrosion resistance are better than ordinary polyethylene pipes. In industrial and mining enterprises, this composite pipe can be used instead of steel pipes for conveying pipes for corrosive media such as oil and gas or for mine ventilation pipelines.

[0003] The existing PE composite pipes still have some defects. During actual use, the most obvious defect of PE composite pipes is that the overall structural strength of the plastic pipe is low and it is easy to break under pressure, thus affecting subsequent use. For this reason, we propose a PE composite pipe structure. Utility Model Content
