Scope
Scope: This standard specifies the insulation pipes and fittings of town heating ductile iron pipes, pipe layout and installation, pipe stress calculation, fixed pier design, pipe construction and acceptance, and operation and maintenance. This standard applies to the design, construction, acceptance, and operation management of new, renovated, and expanded town heating pipelines using ductile iron pipes as the pipe material and water as the medium, with a design pressure of water less than or equal to 2.5MPa and a design temperature less than or equal to 130℃, and a nominal diameter of the pipe less than or equal to DN1600. For town heating pipeline projects designed and constructed in areas such as earthquake zones, collapsible loess, and expansive soils, in addition to complying with this standard, they shall also comply with the relevant provisions of GB 50032, GB 50025, and GB 50112. The design, construction, acceptance, and operation management of town heating ductile iron pipeline projects shall, in addition to complying with this standard, also comply with the provisions of current national standards.
