TUBE MILLS & ROLLFORMING LINES

Direct-forming square and rectangular welded pipe mills

upgrading and renovation of old equipment. Apart from a small number of new factories, most factories have ready-made welded pipe mills, a lot of varied rollers and other rather advanced equipment. It is really wasteful to change them. At this time the remodeling option can be made, so that all the equipment and rollers can remain. There are signs that the development trend of square and rectangular pipe mill will go to the all-flexible model, and the market for square and rectangular pipes will get more active. This is because in the future factories will need to meet all the demands and requirements of customers, including any shape, any size, any thickness, any r angle, any length, any material and any quantity. Factories will produce according to orders, the limit of the minimum order quantity will be lifted, and even customers can bring their own materials for processing. Factories will not stock materials anymore, and the prices of square and rectangular pipes will be lower than that of round pipes.

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(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 mentioned above, 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, water and gas. For the customer whose demand for production capacity can be met with only one production line, CNC CFS(R) square and rectangular (round) pipe mill can save so much investment that it is truly worthwhile to make the best use of this production line. CNC-CFS(R) square and rectangular (round) pipe mill can also work for

CNC-CFS is a fully flexible square and rectangular pipe mill, which can change the specification automatically in a short time by entering the product details on the screen interface. 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 waste. 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 few pipes. 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

Cut-off blades and dies for tube cutting mills

spends less on their total tooling budget each year. The user can also benefit from the potential of blades lasting even longer by adding coatings. Randolph Tool Co has many different coatings available to suit the material that is being cut. You can contact Randolph Tool Co for a consultation to see if it can reduce the down time of your tube mill. By collaborating with its customers the company hopes to help boost efficiency.

RANDOLPH Tool vertical and horizontal tube cut-off blades and jaws/dies are manufactured with the latest tooling processes, by skilled craftsmen to guarantee that the blades are extremely flat and smooth. The flat and smooth blades cause less friction during the cutting process, which in turn makes the tooling last longer. The longer the customer’s tooling lasts, the less down time they will have on their tube mill, which means more production time on the mill. The blades lasting longer will also mean that the user
