**Manufacturing Method of Tantalum Tubes** Tantalum tubes come in welded and seamless types. - Welded tubes are produced by shaping a strip into a tube form and welding the seam using GTAW. - Seamless tubes are made through extrusion, shrinkage, or deep drawing from a plate. **Industries Suitable for Tantalum Tube Adoption** - Tantalum is used in corrosive environments and superconducting fields. It is processed into corrosion-resistant nozzles and electrode tubes. Tantalum is also widely used in the chemical industry for manufacturing parts such as reaction vessels, pipes, condensers, heat exchangers, spiral coils, U-tubes, thermocouple protection tubes, and liquid metal containers and pipes.

Checking and maintaining the position of the coils in the hot coil water cooling pool, as well as lifting them, is a dangerous and difficult task. This product recognizes the holes through sensor detection when the lifter descends and automatically stops where there is a coil hole. The arm closes and inserts claws into the coil hole. When the coil is lifted, the stock detection sensor activates, and a safety device operates to prevent the arm from accidentally opening and dropping the coil during transport. In addition, various safety measures are incorporated into the design to support 24-hour unmanned operation.
