Description

Technical Field

[0001] The utility model relates to the technical field of gas pipe safety, in particular to a high temperature resistant safety HDPE gas pipe. Background Art

[0002] In many cities and regions, natural gas is one of the main energy sources, used for heating, cooking, industrial production, etc. In order to ensure that natural gas can be safely and efficiently delivered to users, the pipeline system must have high temperature resistance and safety performance. Traditionally, metal pipes such as steel pipes have been used for natural gas transportation, but they have some problems, such as easy corrosion, heavy weight, high installation and maintenance costs, etc. In order to overcome these problems, people began to look for lighter, more corrosion-resistant, easier to install and more economical alternative materials. HDPE material has become an ideal choice due to its excellent performance. HDPE pipes have excellent chemical corrosion resistance and can resist the erosion of chemicals in natural gas. In addition, HDPE pipes are light in weight, easy to transport and install, and have a long service life.

[0003] After searching, the patent number "CN113566028A" mentioned in the text that "the present invention discloses a high-temperature resistant safe HDPE gas pipe, including a pipe body, a wear-resistant cast stone layer, a high-density polyethylene pipe base layer, an anti-corrosion latex layer and a tempered pressure-resistant layer, the anti-corrosion latex layer is provided at the edge position inside the pipe body, and the tempered pressure-resistant layer is provided at the edge position inside the pipe body on one side of the anti-corrosion latex layer, and the high-density polyethylene pipe base layer is provided at the edge position inside the pipe body on the side of the tempered pressure-resistant layer away from the anti-corrosion latex layer, the high-density polyethylene pipe base layer is provided at the edge position inside the pipe body on the side of the high-density polyethylene pipe base layer away from the tempered pressure-resistant layer, and the flame-retardant rubber ... A wear-resistant cast stone layer is provided at the inner edge of the pipe body on one side of the base layer of the high-density polyethylene pipe fitting.

When in use, a flame-retardant rubber layer and a wear-resistant cast stone layer are provided on the edge of the pipe body. In this way, the pipe is not easily subject to external wear during long-term use, prolongs the service life of the gas pipe, and improves the convenience of using the gas pipe.
