The mining industry requires the use durable machinery in the processes that are undertaken. However, steel pipes are usually fitted in such machines are not all that durable. This is because they are exposed to much heat and corrosion during the mining process. Mills are some of such gadgets. They are located in furnaces to pass out steam to the atmosphere since they are placed near furnaces. Used tube mill usually serves the same purpose.
Various types of pipes are available. One of them is the low speed pipe. This type is usually fitted with a rotating cylinder shell and thus can be rotated easily. This is made possible by easy passing of the slurry as a final product. Medium pipes are those which are needed for crushing of coal. Most of the mills have these pipes in place. The medium pipes are installed initially.
Due to the high temperatures usually subjected to such pipes, their life span usually decreases in a great rate. They depreciate greatly due to exposure of various chemicals since they corrode them most times. In most cases, the already depreciated pipes are sold to local metal dealers if these are beyond repair. However, most of them are recycled and put to other uses, after repair.
The second hand pipes are not entirely disposed of without recycling them. It is vital for one to understand the recycling process of such pipes. In most recycling companies, a special manufacturing machine is installed in them. It deals exclusively with the repair and putting to use the corroded pipes. Reshaping of such pipes is done among other steps like cleaning them from chemicals and dirt.
A special scanning machine is required in inspecting the pipes. Second hand tubes are passed on it hence detection of cracks and defects is made easier. Laser scanners are necessary, laser beams on these pipes do check on cracks. The machine works at a great speed making sure no mounting of pipes is done in order to eliminate delay in the receiving bay.
Reinstatement follows next. This step is whereby the annealed strips are required to seal defects that are found on the machine. The strips are slit and cut. These are then cut into the required sizes. After that they are fixed at the required points.
Strip pickling section helps in ensuring that repairing process runs smoothly hence ensure that no faults are made. The used pipes are then removed off the excess strips making sure that no waste was done. A bright finish is then made, ensuring that designs and specialties are made on the pipes. Welding process then follows after to ensure they are in a stable solid state.
There are other processes that the pipes go through. They include straightening, reshaping and eddy examinations. Once the processes are done, they are ready for sale. Clients are informed that they are secondhand before they purchase them.
