The design and working pressure of high-pressure boiler tubes in Jiangsu depend on specific applications and requirements, so different types of high-pressure boiler tubes may have different pressure levels. Generally speaking, the pressure of high-pressure boiler tubes can be divided into the following common levels:Low pressure boiler tube: Low pressure boilers are usually designed to operate at lower pressures, typically within the range of 0.1 to 2.5 megapascals (MPa). These boilers are mainly used for heating, hot water, and some industrial processes.

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.

In addition, there are also differences in the scope of application between the two. Precision steel pipes are mainly used in fields such as mechanical manufacturing, automotive parts, industrial equipment, and high-precision instruments and meters. Due to the characteristics of high precision, high strength, and wear resistance, precision steel pipes often meet the high requirements for material performance in these fields. Ordinary steel pipes are mainly used in fields such as construction, water conservancy, energy, and chemical engineering, such as conveying fluids and structural support. In contrast, the requirements for ordinary steel pipes are relatively low and the price is relatively low.

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.

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.
