Square Duct is mainly used for air duct,and it has several obvious advantages against previous rectangular duct:
First,it can increase the strength, because every bite there is strengthening rib.
Second,High efficiency, feed speed of 38 meters per minute is impossible for rectangular duct production;
Third,Reduce consumption and save energy:It is of vortex shape when the air pass from the duct,using the sprial duct can reduce resistance.Morever,cleaning is very convenient because there are professional cleaning tools and no dirt corners on the inner wall of the Spiral Tubeformer with outside corrugations and outside lock seam.
So it can not only save material, to be very economical, but also can improve the air flow.
There are two distinguishing products of SBKJ:
One is flying shear type sprial tubeformer,model:SBTF- 1602 tube machine.What are the advantages of it?
First,as use of the stable forming dies,there is no size bias in the operation.The other advantage is that there are hardly scratches on the surface, so the it can satisfy the high requirements of places like airport and clean room.
Another product SBTF-1500D tube former with a big technology breakthrough.It increases a roll-type cutting shear on the basis of our previous product SBTF-1500 pipe machinery.The advantage is:
no need of forming dies
can produce pipe between diameter 80mm and 1500mm with the change of one metal band
the breakthrough is the roll-type cutting shear,no noise and no scratche
The module technique gives the customer the possibility to choose
between a number of options, allowing him to create a machine a number of options, allowing him to create a machine for his specific needs.
The frequency controlled main drive ensures a smooth acceleration and an almost noiseless operation.
The outstanding patented flying slitter cuts the tubes to lengthwithout noise or hot sparks as known from the saws and provides smooth tube ends without deburring.
The design and options fulfill the needs in HVAC to produce in mild steel, galvanized steel, stainless steel or aluminum
The corrugation unit allows a reduction in material costs and makes the bigger diameter tubes more rigid.
