Mastering the correct operation method can not only ensure the sealing effect of pipeline plugging air bags but also effectively extend the product's service life. Based on years of construction experience, the standard construction steps are summarized as follows, which beginners can directly refer to for operation:
1. First, clean the gravel, sludge, and sharp debris on the inner wall of the pipeline to avoid scratching the airbag; Subsequently, place the airbags flat into the pipeline, ensuring that the airbags are placed upright, without distortion or wrinkles, and aligned with the section that needs to be sealed to ensure subsequent sealing.
2. Connect the inflation pump tightly to the airbag intake valve, slowly inflate compressed air, and monitor the pressure value in real time with a pressure gauge throughout the process. Once the corresponding standard air pressure is reached, immediately stop inflating and close the intake valve to prevent damage to the airbag caused by high air pressure.
3. Check the inflation status of the airbag by standing still, confirm that the airbag is firmly attached to the pipe wall and tightly sealed, and then carry out subsequent construction such as pipeline maintenance, dredging, and water cut-off; During the construction process, it is strictly prohibited for vibrating rods or sharp tools to directly collide or scratch the surface of the airbag.
4. After all construction is completed, open the intake valve and slowly release air. Do not release air quickly, which may damage the airbag; After the airbag has fully contracted and softened, smoothly extract it from the pipeline, clean the surface stains and impurities with clean water, and store it properly for future reuse.
Proper daily maintenance of Pipeline Plugging Airbags can effectively reduce the probability of damage and extend their service life. In response to the maintenance needs of construction units, practical storage and maintenance precautions are summarized:
1. After each use, rinse the mud and dirt on the surface of the airbag with clean water in a timely manner, and place it in a cool and ventilated place to dry thoroughly. It is strictly prohibited to expose it to sunlight or rain, and it should be kept away from chemical corrosion such as oil stains, acid and alkali to prevent rubber aging and cracking.
2. When storing, it is recommended to lay it flat or hang it for storage, avoiding folding and squeezing, heavy objects crushing, and keeping it away from sharp objects such as nails and steel bars to prevent the surface of the airbag from being scratched or leaking.
3. If there are minor issues such as slight air leakage or detachment of sealing film in Pipeline Plugging Airbags, professional repair can be carried out; After the repair is completed, it is necessary to conduct water and air pressure tests to confirm that there is no leakage or damage, and then put it back into construction use.
1.What construction scenarios are Pipeline Plugging Airbags suitable for?
Pipeline Plugging Airbags are mainly used for scenarios such as water supply and drainage pipelines, sewage pipelines, and water conveyance culverts, emergency repairs, dredging and reconstruction, and segmented pressure testing. The circular diameter has the best adaptability and more stable sealing effect.
2.What should I do if pipeline plugging airbags are inflated and overpressure occurs?
Overpressure inflation can easily lead to the rupture of the rubber layer and damage to the internal fiber skeleton, which is highly likely to be irreparable and unusable; Once overpressure is detected, immediately stop inflating and slowly deflate to the standard pressure value. Construction with overpressure is strictly prohibited.
3.Can non-standard pipe diameters be customized with pipeline plugging airbags?
Customization is possible by providing key parameters such as pipeline inner diameter, length, and construction pressure. Manufacturers can process pipeline plugging airbags according to their needs, ensuring the adhesion between the airbag and the pipe wall, guaranteeing the sealing effect and safety of use.
4.How many times can these airbags be used?
Under the premise of standardized operation, proper storage, and timely repair of minor damages, the airbags can be reused dozens of times, and their service life mainly depends on the construction environment and the degree of operation standardization.
