The metal part is made of corrosion resistant material to maximize the service life of the equipment.   

Preparation before use

✱1. clean and inspect airbags and accessories carefully before and after each use.

Check the air bag carefully to ensure no cuts and perforations, no bubbles and no wear parts between the rubber layers. At the same time, the joint and roller structure must work normally.

🍬Check the control valve. The inflatable hose includes the quick matching connector and the gas nozzle working normally.

Every time before and after use, water or detergent can be used to clean the airbags easily, but do not use any gasoline, alcohol or other organic solvents, such as hydrocarbon or strong alkaline solvent, to clean the air bag.   

🅘2. please be sure to choose the right size airbag according to the actual diameter.

After the development and production of each repair balloon, the diameter of the pipe has been clearly determined. This area has been identified on the apparent position of the balloon. Please be careful.   

𒐪Before using the air bag, be sure to carefully measure the inner diameter of the pipe and ensure that the value is within the safe scope of the air bag marked on the selected airbag before proceeding with the next step.

𒊎It is strictly forbidden to use the repaired air bag to be used in a large or too small pipe outside the safe use scope of its marking.

♛3. make sure you select safe and reliable inflatable hoses and control valves.

Before use, check the safety control valves and inflatable hoses, including the quick matching nipple and the gas nozzle. Please make sure that they are clean, which directly affect the normal operation of the airbags. .

Never adjust the safety control valve privately.

If you think there is any damage to repair the airbag or its accessories, please contact us or VAPOs.r.o company to arrange professional inspection, troubleshooting, maintenance or replacement.   

🥂4. please wear full safety clothing and safety facilities and operate airbags again.

൲When repairing airbags, be sure to wear protective clothing, safety helmets and eye protection glasses.

𒁃If the pipeline to be repaired is a municipal sewer, please read carefully the safety regulations for repair work in narrow space or related industries, otherwise it will directly cause life danger.

🌞5. correctly install the airbag roller, which should be carefully verified before operation.

If the angle of the mounting structure of the airbag is not suitable, it will be difficult for the airbag to enter the pipeline smoothly and reach the location to be repaired quickly. Due to the fast curing speed of the resin, the repaired airbag reaches the defect location as fast as possible. Any delay in time may affect the quality of the repaired, or even directly damage the air bag.

6. do not allow airbags to contact chemicals.

Wrap the woven fabric impregnated with pipe repair chemicals on the repair airbag before using the PE foil or the appropriate coating to protect the airbag, so as to prevent chemical substances from corroding the rubber on the airbag. If the coating scheme is adopted, it is recommended to press the air pressure of 0.2bar before coating the airbag protection layer. This facilitates the perfect penetration of the coating into all pores of the rubber part of the balloon.   

Improper coverage to repair the airbag protection layer may cause chemical reactions on the surface of the gasbag to damage or damage airbags. Do not use organic solvents, hydrocarbons and other corrosive coating agents as protective coatings.   

🍌7. clean the pipe and then put the air bag in the pipeline. It is strictly forbidden to place the balloon directly inside the pipe with foreign bodies or sharp objects.

Before installing the repair balloon into the pipeline to be repaired, be sure to clean up the pipes, remove sand, mud, stones, and any other sharp objects that can damage the air bag. In most cases, we need to wash the pipes with high pressure before washing the airbags. At the same time, we suggest that after the completion of the repair, we should use pipe crawler to do video detection of the repaired segment to ensure the quality of repair.
