The following are some installation methods of ventilation pipes in metal processing plants:

1. On-site measurement and planning: accurately measure the size and plan the direction of the pipeline according to the layout and ventilation requirements of the workshop.

2. Support and hanger installation: Install appropriate support and hanger to support the ventilation duct and ensure stability.

3. Pipeline section installation: the pipeline is assembled in sections according to the design requirements, and each section of the pipeline can be connected by bolts, welding, etc.

4. Connect with the equipment: accurately connect the ventilation pipe with the exhaust fan, tuyere and other equipment to ensure a good seal.

5. Adjustment and fixing: Adjust and fix the position and levelness of the pipeline after installation to prevent shaking.

6. Sealing treatment: the connection parts are sealed to prevent air leakage.

7. Test and acceptance: After the installation is completed, the ventilation effect is tested to ensure that the requirements are met.
