Rubber Rings Factory introduces the relevant knowledge of pipe purge and pressure test:
After the polyethylene piping system installation is completed, after the appearance is qualified, the entire system shall be purged in sections. Although it is required to ensure that the pipeline is clean and free of foreign matter during construction, it should be cleaned before the pipeline experiment. The cleaning medium should be compressed air. Static electricity occurs when the polyethylene pipe is purged. The accumulation of this static electricity will generate a high voltage and cause damage to the human body. Therefore, the following methods should be adopted when purging:
The purge port should use a steel pipe with a length of not less than 4m, and a purge valve should be installed on the steel pipe; the steel pipe of the purge port must be well grounded, and its grounding resistance should not be greater than 10Ω, so as to introduce static electricity into the ground; when using air When purging, it is necessary to slowly replace the air in the pipe with the air before purging with a high-speed airflow.
Through the above introduction, Pe Tubes Manufacturers hopes that you can simply refer to the content of this article in future use.
