Ventilation ducts are not new to everyone. They are our large indoor ventilation equipment. We can see them in some large public places, such as office buildings and shopping centers. Ventilation duct is a kind of hollow pipe, mostly round or square. The quality of ventilation pipe production and processing has a great impact on the later use and the safety factor of operators. Therefore, it is necessary for operators to understand the precautions of ventilation pipe processing.

1.通风91在线视频观看加工过程中，应尽可能避免纵向接缝，但不应出现横向接缝。此外，根据设计清洁度要求，通风管的底切和四角需要用密封胶密封。此外，通气管接头的密封面应设置在通气管壁的正压侧。

1. In the process of ventilation pipe processing, longitudinal joints should be avoided as far as possible, but transverse joints should not appear. In addition, according to the design cleanliness requirements, the undercut and four corners of the ventilation pipe need to be sealed with sealant. In addition, the sealing surface of the vent pipe joint should be set on the positive pressure side of the ventilation pipe wall.

2.在风管加工过程中，通风91在线视频观看不能设置加强框架或加强筋，因为这会对通风91在线视频观看的质量产生一定的影响。

2. In the process of air duct processing, the reinforced frame or reinforcing rib cannot be set in the ventilation pipe, because it will have a certain impact on the quality of the ventilation pipe.

3.风管加工不能采用“S”形切割和“C”形直角切割的连接方式。此外，一些特殊的通风91在线视频观看不能堵塞。

3. The connection mode of "s" shape cutting and "C" right angle cutting can not be used in 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。只有达到清洗标准后，才能及时密封。

4. After the ventilation pipe is finished, clean it with cleaning solution. Only when the cleaning standard is reached can it be sealed in time.

5.当玻璃纤维复合板的气嘴为一段时，在组装法兰接头前，管端的该段应用胶带或胶液密封，防止玻璃纤维外露和散落。

5. When the air nozzle of glass fiber composite board is one section, before assembling the flange joint, the section of pipe end shall be sealed with adhesive tape or glue liquid to prevent glass fiber exposure and scattering.

6.如果是彩色涂层钢板通风91在线视频观看，内壁应保持光滑，在通风91在线视频观看加工过程中涂层不应损坏。如果零件损坏，表面应涂上环氧树脂。此外，风管加工过程中应采取防腐措施。不应使用空心铆钉。组装通风91在线视频观看零件时，这些零件应镀锌。

6. If it is a color coated steel ventilation pipe, the inner wall should be kept smooth, and the coating should not be damaged during the processing of the ventilation pipe. If the parts are damaged, the surface should be coated with epoxy resin. In addition, anti-corrosion measures should be taken in the process of air duct processing. Blind rivets shall not be used. When assembling ventilation duct parts, these parts shall be galvanized.
