请问在设计换热器的时候,如是卧式带膨胀节的,是否需要在膨胀节上开排净孔呢?(即为最低处),是否合适该coda UG-25(f) Openings for Drain. Vessels subject to corrosion shall be supplied with a suitable drain opening at the lowest point practicable in the vessel; or a pipe may be used extending inward from any other location to within 1⁄4 in.(6 mm) of the lowest point. |
