Medium pressure boiler tube: Medium pressure boilers operate at medium pressure, typically within the range of 2.5 to 6.0 MPa. They are used in some industrial applications to generate steam, such as in the chemical industry.High pressure boiler tubes: High pressure boiler tubes are designed to operate at relatively high pressures, typically in the range of 6.0 to 13.0 MPa or higher. These boilers are typically used in large power plants and industrial processes to generate high-temperature and high-pressure steam.

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.

Precision steel pipes have many advantages, but there are also some drawbacks. The following are the main advantages and disadvantages of precision steel pipes, as introduced by precision steel pipe manufacturers: Advantages:High dimensional accuracy: Precision steel pipes have a high degree of dimensional accuracy, and the tolerances for outer diameter and inner diameter are usually very small to ensure dimensional accuracy.Smooth surface: The inner and outer surfaces of precision steel pipes are usually very smooth, reducing the resistance of fluid flow and suitable for applications with high surface requirements.

Testing and quality control: Conduct various tests, including visual inspection, dimensional measurement, non-destructive testing, and chemical composition analysis, to ensure the quality of the pipeline.Surface treatment: To treat the surface of pipelines to improve their anti-corrosion performance, such as galvanizing, spraying, or other anti-corrosion methods.Packaging and Protection: Properly package and protect pipelines to avoid damage during transportation and storage.The production process of high-pressure boiler tubes requires strict quality control and operations that comply with international standards. Any improper operation at any step may affect the quality and performance of the pipeline, therefore accurate production processes and quality testing are required.

Complex manufacturing process: The manufacturing process of high-pressure boiler tubes is relatively complex, requiring multiple processes for processing and treatment. Common processes include forging, cold extrusion, hot rolling, hot extrusion, thermal expansion, and heat treatment. During the manufacturing process, the pipes need to be processed and processed multiple times to ensure that their dimensional accuracy and physical properties meet the requirements.In short, high-pressure boiler pipes are a type of pipeline used in high-temperature and high-pressure environments, with strong resistance to high pressure, good high-temperature performance, reliable connection methods, smooth surface, high corrosion resistance, and complex manufacturing processes. It plays an important role in various high-pressure boiler systems, ensuring the safe and stable operation of the system.
