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.

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.

Pickling or pickling oil grinding: Conduct pickling treatment on pipelines to remove oxides, or perform pickling oil grinding to improve surface quality. This helps to reduce corrosion and improve the surface smoothness of pipelines. Cold drawing or cold drawing: Use a cold drawing machine or cold drawing machine to stretch the pipeline to further reduce size, improve surface quality, and ensure accurate size of the pipeline.Cutting and sizing: Cut the pipeline to the required length to meet the specification requirements.Mechanical performance testing: The high-pressure boiler tube manufacturer conducts mechanical performance tests on the pipeline, including tensile, hardness, and impact tests, to ensure that its performance meets the standards.
