山东通风管道加工及设计要注意的问题

设定思路Design points要通过某些系统的的某些楼高管材设计图纸，并不标界面地段。According to the pipeline drawing of a certain floor of a system, and indicate the interface location.管道网的设计的概念应向基础开使编码，基础平常为端口地方，相当截面积外形尺寸相当段长度的网络节点应给相当编码，应按次序编码。为了能让容易有机构的装修工程。The design of pipelines should be numbered from the starting point, which is generally the interface position. Nodes with the same cross-sectional specifications and length should be numbered in the same order. For the convenience of organized construction.管的开发不得表示构成吊架的地理地位，构成吊架的地理地位隔和各种原料的外形尺寸所需不符合后述外形尺寸必须和枝术法规。The design of pipelines should display the position of branch hangers, and the spacing of branch hangers and the specifications of all materials should comply with the following specifications and technical regulations.

西北排的管道的方案应合理综合考虑异径三通和內径提供国内外同舟异径三通必须內径总长必须。The design of ventilation ducts in Shandong should prioritize considering elbows and inner diameters that meet the inner diameter length requirements of concentric elbows.管网方案应标出弯头尺寸定位变径定位管网定位轴线定位管网下方标高。The pipeline design should indicate the position of the bend, the position of the pipeline axis, and the elevation of the pipeline bottom.制作加工需用主要的疑问Issues to be noted in processing送通风风pvcpvc管道手工加工不可以在于外部设置成框架梁骨架或框架梁，若果“添加会作用pvcpvc管道的产品质量。The processing of ventilation ducts cannot have steel reinforcement skeletons or steel bars installed inside, as adding them will affect the quality of the ducts.生产制造不允许选择c型锐角复制到和s型复制到的对接行为。 针对于特殊化管材，不允许采取卡扣式带动口。透气管控作已完成后，必须要用除垢液除垢，满足规定后才华来进行密封圈。The connection method of C-shaped right angle insertion and S-shaped insertion cannot be used for processing. For special pipelines, snap on bite openings cannot be used. After the production of the ventilation pipe is completed, it needs to be cleaned with cleaning solution to meet the standards before sealing can be carried out.减小管工艺工艺具体步骤中导致双重联系缝隙，并不能双重缝隙，或者管空隙应根据设计的干净平行规范用填料密封剂梗塞，管装饰板材缝隙的填料密封面应坐落透气管壁的压缩空气侧。河南透气管工艺工艺具体步骤中应通过采取防腐涂料的措施。管铸件要求电镀锌。Reduce the occurrence of longitudinal joints during pipeline processing, instead of transverse joints, and the pipeline gap should be blocked with sealant according to the design cleanliness level requirements. The sealing surface of the pipeline plate joint should be located on the positive pressure side of the ventilation pipeline wall. Anti corrosion measures should be taken during the processing of ventilation pipes in Shandong. Pipeline parts need to be galvanized.
