1. Flexible materials should be selected that are resistant to corrosion, moisture, air and mold. Measures should be taken to prevent condensation in the air conditioning system, and smooth inner walls and low dust-generating materials should be used to purify the air conditioning system.
2. The length of the flexible short tube should usually be 150-300mm, and their connection should be tight, firm and reliable.
3. Flexible stubs shall not be used to reduce the number of connecting tubes for alignment and flat connections.
4. The length of flexible stubs at structural deformation joints shall be the width of the deformation joint plus 100mm or more.
Inspection quantity: 10% of the samples should be randomly selected according to the quantity, but not less than 1 sample.
Inspection method: Measure and observe with a ruler.
Description: The main function of the flexible short pipe is vibration isolation, usually used as a pipe in the piping system in the inlet and outlet of the fan or the inlet and outlet of the electric air conditioning equipment; sometimes used as an extension pipe in the settlement joint of the building
2.Smoke control system in the flexible short tube production and connection specifications and basic requirements
Specification: Smoke control system in the flexible short tube production material is not combustible.
The basic requirements: Do not twist, deform or misplace, and do not use it for small or large heads.
3, Select flexible short tube guide:1. Green: Flexible short pipes made of general-purpose materials for air supply and exhaust systems.
2. Red: A flexible short tube made of non-combustible material, used in flue gas exhaust pipes.
3. The length of the canvas soft joint is 150-300mm.
4, flexible short tube-fire soft connection instruction:flexible short pipe shall not be used as a connection to reduce the alignment and leveling of the connecting pipe. When using flexible short pipes in air conditioning systems, measures should be taken to prevent condensation.
1. Rubber damping pads or spring dampers should be used at the contact point between the floor standing fan and the foundation to reduce vibration; the boundary between equipment and infrastructure is obvious.
2. At the soft connection with the fan, a bracket needs to be installed for the air pipe.
5, flexible short pipe connection method:The air pipe and fan adopt a flexible connection method: clamp connection.
The air pipe and the fan adopt a flexible connection method: flange connection.
compensation measures should be taken through the air pipe of the building deformation joint: the length of the flexible short pipe should be the width of the deformation joint plus 100mm or more.
