TUBE MILLS & ROLLFORMING LINES

Directly forming square and rectangular welded pipe mills from FD Machinery

CNC-CFS(R) square and rectangular (round) pipe mill ingeniously puts the functions of two production lines on only one mill, efficiently utilising the same entry section, welding and annealing section, detecting and checking section, zinc-spraying and paint-spraying device, flying saw and code-spraying machine, de-watering and oiling section and bundling machine. Apart from the cost for the equipment, which normally costs three to five times that of the main equipment, it also saves the cost for the land, factory building, labour and the investment in power. For the customer whose demand for production capacity can be met with one line, a CNC-CFS(R) square and rectangular (round) pipe mill can save even more investment.

For the CNC-CFS all-flexible square and rectangular pipe mill, its outstanding performance is conspicuous while its shortage is that it can only produce square and rectangular pipes, but not round pipes or other types of pipes and profiles. CNC-CFS(R) square and rectangular (round) pipe mill is the latest technology and a patented product developed by FD Machinery. Its main feature is that it keeps all the characters of CNC-CFC as it is producing square and rectangular pipes, while it has all the characters of round pipe mill as it is producing round pipes as well as other types of pipes and profiles. It only takes 15 to 30 minutes to automatically complete the transforming from round pipe mill to CFS or from CFS back to round pipe mill only by pressing buttons. No commissioning test is needed, so production can continue immediately, wasting no materials.

CNC-CFS is a fully flexible square and rectangular pipe mill, which can change the specification automatically in a very short time by simply entering the product specification on the screen. One set of rollers can produce any size within the production range, and the rollers do not need to be changed, so production can continue consistently without commissioning test and materials wasted. Taking changing specifications two times a day as an example, the finished product ratio can reach more than 99.95 per cent. From feeding to collecting, the whole process is automated and electrified, and only three or four operators are needed. It enhances the capacity of the equipment largely, reduces the production cost, shortens the lead time and decreases the minimum quantity of the order, which can even go down to the extent of a handful of pipes.
