Product Description

Fireproof Inflatable Duct Seal System
For the convenience of laying, moving and replacing, the cable is built with duct holes reserved, so in case of fire, it is easy for the fire to spread quickly through the pipe holes. In the event of a flood, muddy water will also flow into the pipe hole and settle, leaving behind mud, which will wear out the cable skin the next time the cable is moved. In order to reduce the damage of fire, flood and insect disaster, it is necessary to effectively block the cable holes and prevent the disaster from spreading in the pipeline.Fortunately,we successfully developed a new type of pipe plugging products (steel mesh fireproof and ratproof sealing System). The product is easy to assemble and detachable, fire resistant inflatable duct seal can be flame retardant over 3hours, ratproof and waterproof.

The steel mesh fireproof and anti-rat seal system is made of 304 stainless steel wire mesh and POLYvinyl chloride sealed bag with a group of divided silica gel. With the silica gel in the long elastic state, the gap between the duct and the cable or cable is sealed to achieve fire resistance, dust and waterproof and small animal protection.The wire mesh can resist the damage of mice and foreign bodies, and the polyvinyl chloride synthetic material can resist corrosion and protect silica gel from aging. The combination of silica gel and steel wire mesh is like rubber solid tire, which has the function of inflatable sealing, supplementing the defects of inflatable sealing such as non-fire resistance and anti-insect bite. It also has elasticity and tightness. Steel wire and silica gel materials have the function of complete non-combustion, its fire resistance reaches more than 3hours, life span of 30-50 years.
Stencil fire retardant sealing system is suitable for the state grid corporation, telecom, mobile, metro group, Marine vessels, oil (petroleum), mining, municipal, Bridges, tunnels and cable duct, tubing, duct sealing, bridge the gaps between the anchorage duct and cable seal, a fire isolation, dust, water proof and animal, and other functions.

Product Features and advantages:

1,Integrates the advantages of inflatable blocking and mechanical rubber blocking, perfecting their functional defects and integrating their functional advantages.

2,The finished product has the functions of fire prevention, water proof, insect and rat proof, dust proof, moisture proof and smoke proof.

Fire Resistance Test
Fire resistance test
Reference GA 304-2012     Plastic pipe fire ring
Fire resistance of steel mesh fire - proof sealing system
Unit: Hours
Test Item Ultimate fire resistance time
Fire resistance 1.5 2.0 2.5 3.0
Test procedure
1 - a specimen should contain plastic pipe (steel pipe Ф 110 alternative), cable (steel pipe q50 alternative), stencil fire retardant sealing parts, such as, gas, gas flame gun fire flame on the stencil fire retardant sealing tape, flame temperature 1300 ℃ C - 1500 ℃. The steel mesh fireproof and anti-rat sealing belt is installed in the gap between the pipe and cable, the length is 120mm. The mineral wool plug is on the back.
2. Determination criteria - Fire integrity. During the test, any of the following situations will occur on the backfire surface of the specimen, indicating that the integrity of the specimen has been lost: a) ignited cotton pad; B) More than 10s of continuous flame discharge.
3. Fireproof insulation - During the test, when the temperature of any point on the test piece's backfire surface rises above 180℃, it indicates that the test piece has lost its insulation.
