The manufacturing of tubing typically starts with fabricating the thick strands into thin strands of metal, then folding and joining them into sturdy products such as decorative tube dressings or boxes. The manufacturing of thin-stack tubing and boxes is performed by turning the stacks and joining them together into the desired shape. The most common shapes produced are: plastic tubing (for household use), metal tubing (such as that used in car exhaust systems), and hollow fiberglass tubing. The welding of thin steel strip into a finished product, including box frames, round tube, or pipe, decorative elements, and internal components, is a multi-billion-dollar industry which had its roots way back over a century ago in a small town called Harrow, in England.
Many things that use today’s modern day tube mills can be formed on these large furnaces because of the flexibility of these pieces of equipment offer. As previously mentioned, these machines are primarily used for forming curved shapes. This ability to cut and shape materials has allowed manufacturers and fabricators in the ability to produce products in a tremendous amount of different shapes. From boxes, to pipes, to decorative shapes, to actual tubs for domestic use, companies can form anything they want to use these tubes. They can even cut the shapes and insert insulation into them to help seal the seams.
Tube molding is commonly used for injection molding purposes because it is capable of producing both thin-stack and wide-stack piping by easily manipulating the different stages of the molding process. Smaller items, such as plastic tubing and metal boxes can be easily formed by applying a convection pattern to the inside of the item while larger items such as oil pipes require pumping or folding over large areas before the item is formed permanently. Because of their flexibility, tube mills allow manufacturers and fabricators to create large-scale items that can fit anywhere.
These types of machines use two basic types of technology in order to provide their capabilities. First, they will have a series of rotating cylinders that are connected to the motor and belt. The length and diameter of the items being formed will dictate how many of these cylinders are needed for each rotation of the belt. In order to determine the diameter of the items needing to be formed, the diameter of the core of the item is measured and multiplied by sixteen. This number is then divided by one hundred million revolutions per minute to get the approximate diameter of each individual revolution of the belt, which then is multiplied by the number of cylinders in each rotation.
The second type of technology used in tube mills is their grinding capability. Grinding of metal can be extremely difficult with other types of machines because of the resistance of the material to grinding. However, these machines have grinding wheels that enable them to grind down shapes and sizes regardless of their size and composition. The two types of ore ball types that these machines can grind to are loose metal and shaped metal. The roughness of the finished product will be dependent on what type of ore the machine is grinding, although the roughness will not be as extreme as it would be with hand held grinders.
A final type of technology used in tube mills is their pumping capability. These machines are capable of extracting liquids from difficult-to-reach areas. For example, a mining company may want to have its pipes tapped for waste water from a deep well. The company would first drill into the earth, but if the hole was too large, they would need to drill more tubes into the ground. This process would take many months, but by using these pipe mills, it could be done quickly and with minimal interruption to production. This also makes these pipe mills ideal for areas that do not have sufficient supplies of natural gas, as well as liquids such as oil and the other types of liquids that require extraction from the ground.
