FLEXIBLE DUCT OF UNDERGROUND VENTILATION

Flexible Pipelines and Injection Air Insufflation

VENTIDUCT "El Tigre" is the best alternative for easy installation and cost substantially less than the metal duct. A flexible ventilation duct used for applications vent (Positive Pressure / download / air insufflation / Air injection). Common ranges of diameters ranging from 8 "to 154" (200mm - 4,000 mm) and in sections (sections) from 5 to 500m in length or according to customer requirements. A user request is made VENTIDUCT Banding (Duct ring installed every certain length).

ESPIRALDUCT

 

ESPIRALDUCT was developed by our company given the need to have a pipeline may be employed in Suction many applications air (suction / Air Extraction / Download negative).

It is also widely used and useful as Elbows, even around well defined corners and occasionally is used as vent (Insufflation / Air Injection / Download positive).

 

TIGRELIPSE

Designed and developed TIGRELIPSE by us for replace vents large circumferential dimension so as to be employed vent in many applications (Positive Pressure / Download air / air insufflation) and aspiration (suction / Air extraction) in areas with top limited in space which could not be used because to shocks that would constantly with equipment used in the mining and tunneling of this way reduces energy costs, increases and unleashed rock.

 

DIVERSITY OF SUSPENSIONS

The suspension system must be simple to install and disassembly. The vent duct should be easily mobilized, according to your needs.

The most recommended due to increased stability in the pipeline flexible. this compound of eyelets PVC reinforced (same material flexible duct) with a suspension hook (Clip type) where the flexible duct messenger wire hooked to the tunnel. This is the cheapest of the suspensions offered by "El Tigre". Have a steel cord reinforcement which serves the suspension and is available at an additional cost to extreme situations such as installations near explosions.

BI - VENTIDUCT

 

BI - VENTIDUCT is a BI - DUCT (is a double circumferential conduit attached symmetrically) flexible ventilation used for vent applications (Positive Pressure / Download Air / blow).

Common ranges diameters ranging from 8 "to 154" (200 to 4,000 mm.) And lengths from 5 to 500 meters or requirements of customer.

 

TIGER-TWIN

DTWIN TIGER-oval Developed product under a system of 2 products together in one body (type SIAMESE) Serves to replace the circumferential duct (VENTIDUCT) in That places require additional space with flows Similar air, Provides an improvement of 25% to 30% space free falling damage to vents circumferential, Allowing the size Maximizes mine of equipment used for mining and tunneling.

TIGER-TWIN this simulation is available from 18 "(450mm) to 60 "(1500mm) and lengths according user request.

 

Triduct

The suspension system must be simple to install and disassembly. The vent duct should be easily mobilized, according to your needs.

The most recommended due to increased stability in the pipeline flexible. this compound of eyelets PVC reinforced (same material flexible duct) with a suspension hook (Clip type) where the flexible duct messenger wire hooked to the tunnel. This is the cheapest of the suspensions offered by "El Tigre". Have a steel cord reinforcement which serves the suspension and is available at an additional cost to extreme situations such as installations near explosions.

REMOVABLE STRAPS PVC

An additional accessory couplings ensure hoops VENTIDUCT steel or PVC or ESPIRALDUCT at various diameters


LOCKING CLAMP PVC Band Flat

Is a clamp band with insurance PVC flat. Used for our Various models of ductwork. Insurance is coating a product with Zinc.


MULTI COUPLINGS - CLIP

Metal clamps are adjustable to give greater security ensuring high pressure applications hoops couplings steel or PVC or ESPIRALDUCT in VENTIDUCT various diameters.

JOINT ZIP / UNION-CLOSING ZIP

A 15 cm from both ends of the flexible duct, contains so divided type zipper closure PVC resistant.

The outer flap provides closing protection and conceals outside and flap inner sealing sleeve. By the principle "to higher pressure, closer union ".

The zipper binding clamp eliminates coupling and the steel ring or PVC duct end.
