JULI® Mining Ventilation Tube for TBM Use Advantages: 

 

1. Since 2006, Foresight has more than 10 years experience of manufacturing ventilation ducts and ventilation duct fabric, and owns a strong R&D team which consists of over 10 engineers graduated from professional school,  exceeds 30 high-speed rapier looms, 3 laminated production lines, several automatic production lines for pvc ventilation duct, which ensures annual production of rolled film over 10,000 tons, pvc ventilation duct fabric 15,000,000 square meters, pvc ventilation duct 2,000,000 meters. Foresight continues to supply all kinds of ventilation ducts for coal mines at home and abroad.

 

 

2. Compared with traditional ducts like rubber, glass fiber and plastic dip, JULI® pvc ventilation duct has advantages of lighter weight, thinner material, higher strength, more convenient installation, maintainance and repairation. Composite cost will be decreased more than 25%.

 

3. Foresight original carbon black surface treatment antistatic technology has won Safety Production Science and Technology Achievement Award issued jointly by SAWS and SACSS. It keeps antistatic value ≤3 x 10after two years application.

 

Now a new environmental friendly antistatic surface treatment techonology with water-based carbon black solvent without VOC emission has been developed, and it can stablish the antistatic value at 3 x 106.

 

 

4. Automatic layflat ventilation duct production line researched and developed by ourselves has made standardization, automation and large scale production come true, and completely avoided the quality variation due to employee turnover caused unstable hand processing and technical differences, released the process cutting material and welding suspension fin, it can be welded and folded automatically, so the working efficiency will be increased 3 times, and the welding tensile strength will be improved 20%.

 

 

5. Customized overlength duct for coal mine is available,and the composite cost will decreased 15%. Foresight explored a new solution for overlength distance air supply, less joint, lower resistance, and lower cost from technology and cost. Customized 5-100m or even more section length is available.

 

Section length Fabric reduction Steel ring reduction Process cost reduction Other reduction Composite cost reduction
30m 2.56% 66.67% 30% 30% 13.5%
50m 3.00% 80% 30% 35% 14.9%
80m 3.36% 87.50% 30% 38% 17.3%

100m

6. JULI® pvc ventilation duct for coal mine is built-up welding to form duct with grommet which makes easy installation and uniform forced.
