  Ventilation pipe is a hollow pipe used for ventilation, mostly round or square. The processing of ventilation duct has a great impact on the use of air duct in the future, and also for the safety of operators. Therefore, it is necessary to understand the precautions for the processing and installation of the ventilation duct. The small editor has sorted out the relevant information and shared it with you. When processing the ventilation duct, there are many things to pay attention to. The following are some common problems:


  However, the transverse joint should not appear in the process of ventilation. Moreover, the bite seam and four corners of the ventilation pipe need to be in accordance with the requirements of the design cleanliness level, and then the sealant should be used to block it tightly. In addition, the sealing surface of the joint of the ventilation pipe plate should be set on the positive pressure side of the ventilation pipe wall.


  2. When processing, it is not allowed to set the reinforcement frame or reinforcement bar inside the ventilation pipe, because it will have a certain impact on the quality of the ventilation pipe.



  3. The connection mode of S-shaped insert and C-type right angle socket cannot be used in the processing of ventilation pipe. In addition, for some special ventilation pipes, the snap on bite can not be used.


  4. After the ventilation pipe is made, it should be cleaned with cleaning solution. Only when it reaches the cleaning standard can it be sealed in time.


  5. When the air duct end of glass fiber composite board is the cutting surface, the cutting surface of the pipe end should be blocked with tape or glue before assembling the flange connector, so as to prevent the glass fiber from being exposed and flying away.


  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 damaged part occurs, it is necessary to brush the surface with epoxy resin. In addition, in the process of ventilation pipe processing, anti-corrosion measures should be taken, and core pulling rivets should not be used. Moreover, when the ventilation pipe parts are assembled, these parts should be galvanized.
