Good high-temperature resistance: High pressure boiler tubes are exposed to high-temperature environments during operation, so they must have good high-temperature resistance. The material selection of high-pressure boiler tubes usually depends on the working temperature and medium. For systems with lower temperatures and moderate pressures, low alloy steel or carbon steel can be chosen; For high-temperature and high-pressure systems, it is necessary to choose high-temperature resistant steel or alloy steel. High pressure boiler tubes are usually subjected to processes such as heat treatment and annealing to ensure that they do not undergo brittle fracture at high temperatures.

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.
