How to Reinforce Ducts for Spiral Duct Machine Manufacturers?

Strengthening of spiral duct machine pipelines

Traditional pipelines will be destroyed after punching, resulting in deformation and even fracture of the pipelines, seriously damaging their ventilation efficiency. If replaced with spiral ducts, the punching effect must be ensured, and the pipe rigidity and hardness must be guaranteed under the action of the spiral skeleton. After testing, the hardness of the stamped spiral duct is three times that of the traditional pipe without ducts.

The reinforcement of the pipeline of the spiral duct machine is to ensure its performance, but not all pipelines need to be reinforced. For circular pipes, in addition to spiral ducts, those with a diameter greater than or equal to 80mm, a pipe length of more than 1250mm, and a total area exceeding 2m need to be reinforced; for rectangular pipes, those with a side length greater than 630mm, insulated pipes with a side length greater than 800mm, pipe lengths greater than 1250mm, or low-pressure air ducts with a single side area greater than 1.2 square meters, and medium/high-pressure pipes greater than 1m also need to be reinforced.

The bolts, nuts, washers, and rivets selected for the pipeline should be made of materials that meet the performance of the pipeline, do not cause electrochemical corrosion or galvanizing, or other anti-corrosion measures. Core pulling rivets cannot be selected. Reinforcement should be carried out using reinforced frame and reinforcement. Pipeline should not be connected by flanges, and S-shaped cutting, right-angle cutting, and vertical cutting should not be used.

Key points to pay attention to when using spiral duct machine's third-generation coiling machine

The operators of the spiral duct machine factory need to be familiar with the structure and use of the coiling machine. They can only operate after being allowed by the management staff.
Before starting up, carefully check whether the safety devices are complete.
During operation, it is strictly prohibited to place the body on the working rolling shaft parts and workpieces.
After work interruption, the clutch should be disengaged to neutral.
Multiple operators of the spiral duct machine factory need someone to instruct the work.
Overloading work is strictly prohibited.
The tilting reset of the lifting and flipping bearing of the upper rolling air duct production line and the misalignment of the upper rolling should be carried out after the main transmission stops.
After work, the power supply should be cut off and the power supply box of the air duct production line should be locked.
