The production of 304 stainless steel pipes follows a precise and controlled process to ensure high quality and performance. It begins with melting raw materials—iron, chromium, and nickel—in an electric furnace. The molten steel is then cast into billets or slabs, which are further processed into seamless or welded pipes.
For seamless pipes, the billets are heated and extruded through a die to achieve the desired shape. In contrast, welded pipes are manufactured by rolling stainless steel sheets into a cylindrical form and joining the edges using advanced welding techniques such as TIG or laser welding.
After forming, the pipes undergo annealing, a heat treatment process that enhances corrosion resistance and mechanical properties. Finally, finishing processes like polishing and surface treatment are applied to meet specific industry standards and customer requirements.
