Extrusion or rolling: The blank tube is formed into the final shape of a seamless tube by gradually reducing the outer diameter and wall thickness through an extrusion or rolling machine. This step requires a high degree of control to ensure that the size and quality of the pipeline meet the specification requirements.Annealing: Annealing is an important heat treatment step that eliminates residual stress and improves the mechanical properties and toughness of pipelines by annealing them at high temperatures.

Chemical composition analysis: By using chemical analysis techniques such as spectral analysis or chemical determination, the chemical composition of pipelines is detected to ensure that the alloy composition meets the requirements.Non destructive testing: includes non-destructive testing methods such as ultrasonic testing, radiographic testing, and magnetic particle testing, used to detect defects, cracks, and corrosion inside pipelines. Pressure testing: Conduct a pressure test by exposing the pipeline to high pressure to test its sealing and pressure resistance. The testing pressure and time should comply with the specifications.

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.
