GB/T 1047-2005 defines the nominal size (DN) for pipework components, providing a standardized numerical designation for the size of pipes, fittings, flanges, and valves. It is applied in fluid systems across industries such as water supply, oil and gas, chemical processing, and HVAC to ensure interchangeability and compatibility between components from different manufacturers. This standard is critical for engineering design, procurement, and installation, where consistent sizing is required for proper system assembly and sealing.
