The super pipe, as its name suggests, is an air duct. It is these large and small pipes that combine to form an indispensable transport network for ventilation, air conditioning, air purification, etc. Vent pipes are usually composed of pipes, connecting accessories and functional components. The pipe fittings are divided into square pipes and round pipes according to the section; The connector includes a variable direction elbow, a variable diameter large head, a variable cross-section square and round head, and a branch tee. Cross and flexible short pipe; Various air outlets, air caps, air valves, static pressure boxes, silencers, filters, air treatment equipment, etc; And the power supply part - ventilator.

Cleaning process of ultra long pipe ventilation pipe.

1. Place the system on the end of the ventilation pipe that has not been cleaned to fully isolate the cleaning area from the non cleaning area and avoid secondary pollution;

2. The high-efficiency vacuum dust removal system is connected with the ventilation duct system, fixed, and the vacuum cleaner is opened;

3. Place the cleaning robot in the air vent and clean it evenly.

4. After the vent is cleaned, turn off the vacuum cleaner and start to deal with the dirt in the collector;

5. Clean the fire damper during operation. If it cannot be cleaned, it shall be cleaned at one side of the fire damper;

6. Conduct monitoring and video recording before, during and after cleaning the ventilation duct, and save the images.

7. Remove the suction pipe and suction pipe disc, clean and disinfect the tuyere, seal the tuyere with rivet gun, seal with sealant, and recover the thermal insulation material;

8. Check the strength of the ceiling of the ventilation duct. If the strength is not enough, the expansion bolts shall be installed on the ceiling and the prefabricated angle steel tray shall be used for reinforcement. On the premise that the strength of the ventilation duct is not affected, the ventilation duct manufacturer recommends that the operation be strictly in accordance with the standard. After the air and filter screen are removed, clean them with high-pressure water gun at the designated position;

9. Collect all clean dirt, seal and send it to the designated place after disinfection;

10. After the ventilation pipes of a set of systems are cleaned, the site shall be sorted out to restore it to its original state;

11. Clean the coil.

Profile steel and aluminum profiles are commonly used for ultra long pipe ventilation pipes. Profiles are usually classified according to the shape of the cross-section and used according to the mechanical properties. For example, flat steel and angle steel are often used to strengthen air ducts and manufacture flanges; Round steel, angle steel, channel steel and steel pipe are commonly used as air duct supports; Channel steel and I-beam are mostly used as frame beams. In terms of technical indicators, the profile size of the ventilation pipe is small.
