In this way, the raw materials used in gas supply polyethylene pipes are self-colored CRP100 with a density of 0.941 and above. In addition to the production operator, the production process of these pipes must be completely under the control and monitoring of computer devices and equipment with high accuracy and sensitivity. Due to their high sensitivity, the laboratory and test results of these pipes are tested more strictly and with special equipment and sometimes special test devices for gas pipes. Another difference between gas pipes and water pipes is the difference in the type of packaging. Due to the sensitivity of these pipes, they should not be in direct contact with uneven, sharp, and rough surfaces, for this reason, the packaging of these pipes, in addition to installing a suitable cap on both sides, is supported by wooden or plastic supports at several points. And then they are loaded and unloaded by special trucks and in a special way.
