The production process of high-pressure boiler tubes usually includes the following main steps:Raw material preparation: Firstly, select appropriate steel or alloy as the raw material. These raw materials are usually provided in the form of steel billets (or steel tube billets), and their chemical composition and dimensions must comply with standards and requirements.Perforation: The steel billet is perforated through a piercing machine, transforming it into a hollow tubular structure, forming the initial shape of a seamless tube.Heating of the blank tube: The blank tube needs to be heated through a heating furnace to improve its plasticity for further processing.
