Billets, or ingots (as they sometimes referred to), are not of practical use until they have been formed into
more functional shapes and sizes. While they have already been put in the furnace, they still require a series
of shaping and molding procedures such as hot and cold working, milling and cutting before they are sold in
hardware stores, or used for different applications. The unformed billets, however, can be used in striking
currency such as coins and as reserves, similar to gold bars.

- Q:How are steel billets used in the manufacturing of pipes and tubes?
- Steel billets are an essential component in the manufacturing of pipes and tubes. These billets, which are typically rectangular or square in shape, serve as the starting point for the production process. They are first heated to a high temperature to make them more malleable and easier to shape. Once heated, the billets are then passed through a series of rollers, where they are gradually formed into a cylindrical shape. This process, known as hot rolling, helps to refine the structure and improve the mechanical properties of the steel. Hot rolling also ensures that the dimensions of the billet are consistent throughout its length. After the initial hot rolling, the billets are further processed through a series of cold rolling and sizing operations. Cold rolling helps to reduce the thickness and improve the surface finish of the billet, while sizing operations ensure that the final product meets the required specifications in terms of diameter, wall thickness, and length. Once the billet has been shaped and sized, it is then cut into specific lengths and welded together to form a seamless or welded pipe or tube. The welding process involves joining the ends of the billets using either electric resistance welding (ERW), submerged arc welding (SAW), or other welding techniques. This helps to create a continuous and strong joint, ensuring the integrity and strength of the pipe or tube.
