对于通风91视频成人网站，91视频APP污可以在一些大型公共场所看到它们，例如写字楼和。通风91视频成人网站是一种空心91视频成人网站，多为圆形或方形。下面讲讲通风91视频成人网站加工安装的六大注意事项具体内容。
For ventilation ducts, we can see them in some large public places, such as office buildings and shopping malls. Ventilation duct is a kind of hollow duct, which is mostly round or square. Next, we will talk about the specific contents of the six precautions for the processing and installation of ventilation pipes.
1、通风91视频成人网站在加工过程中，应尽量避免纵向接缝，但不应出现横向接缝。此外，通风91视频成人网站的底切和拐角需要根据设计清洁度要求用密封胶密封。另外，排气管接头的密封面应设置在排气管壁的正压侧。
1. During the processing of ventilation pipes, longitudinal joints should be avoided as far as possible, but transverse joints should not appear. In addition, the undercut and corner of the ventilation duct need to be sealed with sealant according to the design cleanliness requirements. In addition, the sealing surface of the exhaust pipe joint should be set on the positive pressure side of the exhaust pipe wall.
2、在风管加工过程中，不能在风管上设置加强框或加强筋，因为这样会对风管的质量产生一定的影响。
2. In the process of air duct processing, reinforcing frames or ribs cannot be set on the air duct, because this will have a certain impact on the quality of the air duct.
3、风管加工不能采用“S”型切割和“C”型直角切割的连接方式。此外，一些特殊的通风91视频成人网站不能堵塞。
3. The connection mode of "s" type cutting and "C" type right angle cutting cannot be adopted for air duct processing. In addition, some special ventilation ducts should not be blocked.
4、通风管完成后，用清洗液清洗。只有达到清洁标准后，才能及时封存。
4. After the ventilation pipe is completed, clean it with cleaning fluid. Only after reaching the cleaning standard can it be sealed in time.
5、玻纤复合板的风嘴为截面时，在装配法兰接头前，应将管端截面用胶带或胶水密封，防止玻璃纤维外露和散落。
5. When the air nozzle of the glass fiber composite board is a cross-section, the cross-section of the pipe end should be sealed with tape or glue before assembling the flange joint to prevent the glass fiber from being exposed and scattered.
6、如果是彩涂钢板风管，内壁应保持光滑，风管加工过程中不得损伤涂层。如果零件损坏，表面应涂上环氧树脂。此外，在
山东通风91视频成人网站加工过程中应采取防腐措施。不应使用空心铆钉。装配通风91视频成人网站部件时，这些部件应镀锌。
6. If the air duct is made of color coated steel plate, the inner wall shall be kept smooth, and the coating shall not be damaged during the processing of the air duct. If the parts are damaged, the surface should be coated with epoxy resin. In addition, anti-corrosion measures should be taken during the processing of ventilation pipes in Shandong. Blind rivets should not be used. When assembling ventilation duct components, these components shall be galvanized.
此外风管加工过程中，风管上不得设置加强框或加强筋，不得使用卡扣。制作完成后用清洗液清洗密封，注意零件使用！
In addition, during the processing of air duct, no reinforcing frame or reinforcing rib shall be set on the air duct, and no buckle shall be used. Clean the seal with cleaning fluid after fabrication, and pay attention to the use of parts!
In short, the production and processing of ventilation ducts have a great impact on the later use and the safety factor of operators. Therefore, it is necessary for operators to understand the precautions for processing ventilation ducts. Come to our website for more information http://www.luyunhuanbao.com Come on!
