Radiator branch pipes D. Steam condensate pipes 【Answer】C 【Explanation】The slope of heating pipes during installation should comply with the requirements specified in the design and relevant standards. Hot water heating pipes with steam and water flowing in the same direction + steam pipes with steam and water flowing in the same direction + condensate pipes, shall have a slope of 3‰, and must not be less than 2‰. For hot water heating pipes in which steam and water flow in opposite directions, as well as for steam pipes with steam and water flowing in opposite directions, the slope should be no less than 5‰. The slope of the radiator branch pipes should be 1%, with the slope directed in a way that facilitates exhaust and water drainage
