Scope
Main technical content: 1. To standardize the application of Type II heat-resistant polyethylene (hereinafter referred to as PE-RT Type II) heating pipes in the field of low-temperature heating, ensuring advanced technology, economic feasibility, safe operation, and project quality, these guidelines are hereby formulated. 2. These guidelines apply to the design, construction, and acceptance of PE-RT Type II heating pipelines with a working pressure not exceeding 1.25 MPa (applicable only to S4/SDR9 series pipes and operating conditions with a medium temperature below 45°C), a design temperature not exceeding 75°C, and a nominal outer diameter not exceeding 355 mm. 3. For the design, construction, and acceptance of PE-RT Type II heating pipeline projects, in addition to complying with these guidelines, they shall also comply with the provisions of the current relevant national standards.
