Tube Mills and Piping machinery manufacture pipes and tubes of different dimensions. They serve as the heart of a system to deliver a product uncompromised at both end points. Their shape and composition provide inherent strength to the product, meaning that they are ideal for delivering highly flowable liquid media (e.g. gas, water) through potentially hostile environments without risking catastrophic damage. The versatility of the products they manufacture allows them to be customized to meet the precise requirements of customers.
Tube Mills are manufactured to serve a wide range of customers including pipe manufacturing companies, engineering firms, cement manufacturers, material suppliers, fabricators and retailers. Each type of manufacturing facility and its requirements are unique. Some require high pressure production, some require high temperature tube milling and some require both. The need for customization is inherent to the manufacturing environment and cannot be eliminated. A tube mill can be tailored to meet an engineer’s exact specification or it can be made to specifications provided by the customer. When either the customer or the manufacturer is seeking a custom-made tube mill, it is important to fully understand what is involved in making such a complex machine.
One of the most significant factors in making such a machine is the proper sizing of both the internal and external components. Internal components are those that will be inside the tubes while external components will be those transport materials into the mill. This can range from steel pipes to polyethylene piping and can be extremely important in producing pipe products that are strong enough to withstand stress and provide the necessary functionality.
A tube mill line of steel pipes is typically run through a series of stages while undergoing fabrication. The first stage involves the taper work. During this stage, the pipes are rolled on to a sheet of steel pipe that will be placed into a die. Once the pipe has been located, the sheet will then be fed into the first die where it will undergo taper work, blanking and finally welding.
Electric resistivity welding, or EDW, is often used when manufacturing steel products. This process uses high current alternating current to weld aluminum and copper tube mixtures. This process provides a strong bond to both the inside of the pipe and to the outside surface. Most manufacturers utilize EDW in their tube mills while some fabricators use other types of EDW processes.
Finally, when complete measurements have been taken at various points along the pipe, the manufacturer will perform a cold cutting saw cut to the length that is desired. Tube mills are commonly used during the cold cut stage of this process to reduce waste and maximize the efficiency of the milling and welding process. After the tube mill has been completed, it can be disassembled for further cleaning and restoration procedures. The manufacturer can perform a variety of maintenance operations including replacing worn or contaminated components, reaming, grinding and seating, and topping off all machined parts.
