The growing need of quality air ducts and scarce availability of skilled man power and shortest time duration available for manufacture of ducts, we need to quip with sophisticated CNC machinery to produce quality duct. To overcome these factors for successful execution of project, VENUS has emerged with CNC fabricated machine-made ducts.
VENUS ducts are manufactured using the state-of-the-art world class machine manufactured and imported from U.K.
These machinery assures quality products which meets the requirement of international standards of SMACNA {USA} and DW 144 {U.K.}
ADVANTAGES OF USING FACTORY MADE PRE-FABRICATED DUCTS:
VENUS factory made ducts utilizes the state-of-the-art CAD/CAM sheet metal fabrication machinery.
VENUS has put up its facility, utilizing leading-edge, world class sheet metal fabrication and profiling technology. We provide excellent products for your money.
Superior quality profiles and sections, making use of state-of-the-art CAD/CAM to ensure perfect dimensional products and perfect fitting sections are produced.
SPEED: Efficient handling of the equipment for manufacture of ducts considerably reduces fabrication and therefore job completion time is minimum.
COST EFFECTIVE: An innovative approach of transporting pre-performed sections {instead of more blank sheets} enables easy assemblying and installation at sites all over India-economically and perfectly.
CLEAN JOB SITES: Space requirements is minimum, avoidance of scrap and reduction of noise and disturbance at site..
RAW MATERIAL IN COIL FORM : Prime grade coils of G.I., aluminum and stainless steel sourced directly from the manufactures to get quality materials. This ensures uniformity of material properties, availability of wide range of material specifications as per customer requirements and significantly low wastage.
MANUFACTURING FACILITIES
CAD/CAM MACHINERY : Precision dimensioning, speed and excellent raw material usage are provided by fully automated, computer-controlled machine through the below mentioned machinery.
AUTOFOLDER : Which selects the required sheets, gauge, levels, provides, stiffening ribs, notches, folds and shears for the manufacture of flats “L”, “U” and fully boxed sections.
PLASMA PROFILE CUTTER : Which produces the widest range of profiles for Elbows, tapers, offsets, branches and other sections etc.,
STANDARD SELECTION TABLE
Manufacturing of these profiles is carried out by a small but highly-skilled and trained technical work-force at our factory.
Apart from quality, these machines also ensure timely delivery of ducts system to meet the Project requirements, thus completion of project is faster.
CONCLUSION : The end result of this manufacturing sophistication are, duct profiles and sections which have high strength, low leakage and low vibration characteristics. They require lighter guage material than those produced by conventional means, coupled with the speed of manufacturing, this translates in to unmatched economy and reliability.

PRE-INSULATED PIPES FOR HIGH PERFORMANCE INSULATION SYSTEMS
Shree Venus was established in 1993 for making PUF slabs and pipe sections and PUF pipe supports. Shree Venus also specialized in cast insitu type insulation of pipes and tanks at site. The growing need of quality insulation and for better energy conversation, Venus has emerged with pre-insulated pipes with the help of State-of-the-Art latest machines from Spiro, Switzerland for making spiral seam casing and for pouring of PUF, the machines are imported from Saip Italy.
Advantages of using Pre-insulated pipes with Polyurethane foam are:
Superior strength allows for saving on metal consumption over insulation.
No deformation of shape in case of people walking / Climbing over the pipes after insulation.
Retains the shape and no damage to insulation, in spite of regular foot traffic over the Insulation. Hence maintenance cost is less compared of conventional system.
Water ingress inside the insulations is nil due to seamless insulation of Polyurethane foam and least number of joints on metal jacketing, which prevents the corrosion of inside pipe due to water ingress in case of exposed pipes to weather and hence increases the life of Pipes and insulations.
Site installation of insulation can be reduced to minimum, to cover the elbows, valves, flanges and welding joints and other fittings. Hence, it is economical.
Dependence on labour for site is minimized. Hence, fast completion assured.
FILLED JOINTS
Field joints and fittings like elbows, reducers and Valves are carried out with high pressure Injection machines which ensures uniform quality of foam / density like pre insulated pipe.
High pressure injection ensures the pipe insulation and Spiral casing form an integral part of Seamless pipe insulation system due to uniform foam quality.
The high-pressure machine injection ensures complete filling of irregular surfaces in places like Elbows, Reducers, Valves and Flanges compared to manual pouring method.

FLAT OVAL SPIRAL DUCT AND FITTINGS
Flat Oval Duct has been designed for restricted space conditions that cannot accept round spiral duct. Flat Oval pipe is fabricated in spiral lock seam or longitudinal welded constructions.
Advantages of using Flat Oval Duct:
Fully machine fabricated and hence appealing well.
Light weight due to spiral reinforced wall
Low frictional loss and hence no turbulence
Long run in continuous length up to 3 meters
Simple joining techniques
Reduced space requirements in depth or height
ACOUSTICALLY INSULATED SPLITTERS
Flat Oval and Spiral acoustic splitters for Sound Attenuators is made as Flat Oval Duct but with perforated option with the splitter infill with fiberglass wool / Rockwool which eliminates the use of GI Frame work and reduces the labour for fabrication and fixing of splitters in to the Attenuator Box. The Aero dynamic construction on both the ends facilitates the air movement smoothly without any friction loss/pressure loss. The fully perforated oval shape increases free sound Attenuator and reduces the length normally required with conventional splitters.
Suitable for use in line duct meant for air conditioning and ventilation system
DG Air intake system. Also suitable for sound Attenuators
Air Inlet/Outlet air duct Attenuators
Fan/Blower Silencer ducts etc
Pre - Insulated Double-walled Flat-oval Spiral Duct Systems
Thermal/Acoustic Insulation: A double -walled insulated Flat-oval Spiral Duct consists of an external pressure tight metal shell, a 12.5/25/50mm thick of fiberglass/mineral wool/puf insulation and internal plain protective metal liner for thermal insulation or perforated metal inner liner for acoustic insulation.
