Installation methods and requirements of ventilation pipes and components
管道及附件的可拆卸接口不得安装在墙壁和走道地板上。支架、吊架、支架的预埋件或膨胀螺栓位置应准确、牢固、可靠，埋件不得涂漆，并应清除油污。无保温支架、吊架、支架间距的设计要求应按以下要求执行。水平安装:风管直径或大边长小于40mm，间距=4m；如果大于或等于400mm，间距为3m。垂直安装:间距为≤4m，但每根立管的固定件应大于或等于2根。保温管应符合设计要求。支架、吊架和支架不得设置在风口、阀门和检查门外。吊架不得直接吊在法兰上，并在适当的地方设置固定点，以防止摆动。防火阀、电动风阀等部件的安装必须单独设置吊架。
Removable joints of pipes and accessories shall not be installed on walls and walkway floors. The position of embedded parts or expansion bolts of supports, hangers and supports shall be accurate, firm and reliable. Embedded parts shall not be painted and oil stains shall be removed. The design requirements for the spacing of supports, hangers and supports without insulation shall be in accordance with the following requirements. Horizontal installation: the diameter or large side length of the air duct is less than 40mm, and the spacing =4m; If greater than or equal to 400mm, the spacing shall be 3M. Vertical installation: the spacing shall be ≤ 4m, but the fixed parts of each riser shall be greater than or equal to 2. The insulation pipe shall meet the design requirements. Supports, hangers and supports shall not be set outside air vents, valves and inspection doors. The hanger shall not be directly hung on the flange, and fixed points shall be set at appropriate places to prevent swinging. The installation of fire damper, electric air valve and other components must be provided with hangers separately.
