Product Description

Inflatable Duct Seal System/inInflatable pipe Seal System(IDSS)
IDSS main components "inflatable pipe plugs," is sealed airbags aluminum composite material, the use of inflatable hole principle to achieve the effect of blocking. 
Inflatable tube affixed with waterproof plastic plugs on both sides, waterproof glue when inflated to the pressure of 2.6-2.8 kg, will be piping, 
inflatable pipe plugs, the gap between the three cable completely filled, completely sealed in order to achieve results. 
Inflatable pipe plug hole inside of inflatable silicone material is installed, when the charged gas removal inflatable tube, 
self-filled silicone material properties can be inflated immediately to block holes ensure gas does not leak.

The inflatable Duct Seal System is specially designed for the sealing of the cable duct, Its superior flexible sealing 
performance can better protect the safety of the cable and duct when the duct outlet is blocked.

The inflatable Duct Seal System is suitable for use with polyethylene of lead sheath cables in plastic, concrete or steel 
ducts. It permits cable movement while retaining its sealing properties. It can effectively prevent water or small anminals 
from duct into computer room caused by the accident, also effectively eliminate wells to ensure the progresss of rescue, 
more effective protection of underground duct network system,the workers require a safe environment for working and to 
avoid the risks that occur with the penetration of gas and/or dangerous fluids at the workplace.

The inflatable Duct Seal System has been tested in severe environmental conditions, not corroded by hydrochloric 
acid, alkali and other chemicals. It can be used more than 20 years. Working Temperature IS from -40℃ to 95℃.

Alternative Choice to traditional pipe sealing products,a single cable and/or multiple cables can be installed.

Product Features and advantages

· Flexible seal technology overcomes ground vibration - after the bag is installed, its high pressure inert gas inside makes the whole sealing system elastic, just like wrapping an airbag around the cable in the pipe, thus overcoming irregular frequency vibration from various surfaces.
· Not affected by acid,alkali and other environment -- traditional sealing products such as fireproof mud and cement cannot adapt to underground pipeline environment in rainy areas, and are also prone to cracking due to thermal expansion and cold contraction. IDSS bag material layer design has no pinhole, acid and alkali resistance, and is not corroded by chemical liquid. It can withstand high temperature from 95 ℃ to minus 40 ℃ and is not affected by heat expansion and cold contraction, so it can adapt to all kinds of complex underground pipeline environment.
· Long service life -- The soft metal aluminum layer inside the IDSS bag is the key technology of the bag material, and the detection under the microscope is completely free of pinholes to ensure no gas leakage. The service life of the product is more than 20 years after ammonia gas expansion experiment.
· Quick installation -IDSS single hole installation for 5 minutes, no special cleaning of pipes during installation, greatly improving installation efficiency. It can be removed only by venting air, without damaging the appearance of pipes and cables, low construction and maintenance cost, no need of water source, power support, no need of traditional construction tools.
· Recyclable use of air nozzle structure: the new generation OF IDSS nozzle structure enables multiple use of a single product, greatly reducing the cost of pipe sealing.
· Superior sealing effect -- effectively prevent water, sediment, insects,mouse, rodents and other substances from entering the pipe.
· Sealing cable ducts in running water conditions.


1) the application of different nature (power, communications, construction) pipeline waterproof plugging;
2) Mainly used in underground cable conduit plugging holes, construction of the wall through the wall hole plugging;
3) suitable for plastic, steel, cement and other hard materials pipeline;
4) sealing the hole is limited to circular or elliptical.
