The first standard announcement of 2024 was finally released on March 15th, with a total of 406 new standards released this time. This time, there are only 5 standards related to plastic pipelines, including 5 national standards for heat-resistant polyethylene (PE-RT) pipeline systems and valves. The new standards have brought significant opportunities and challenges to these industries. Now let's hurry up and understand the implementation status of these standards in order to prepare in a timely manner.
