Seamless pipe is the pipe made from a whole piece of metal material after processing, rolling, drawing and other processes. They have the advantages of uniform wall thickness, good surface quality and high dimensional accuracy. Since its production process is more complicated than that of welded pipes, the price of seamless pipes is relatively high.

Pressure resistance parameters of seamless pipes

1. Material strength

The pressure resistance of seamless pipes is closely related to the material strength. Commonly used seamless pipe materials include Q235, Q345, 20#, 16Mn, etc. Their strengths are different, so their pressure resistance is also different. The pressure resistance can be determined by checking the grade of the seamless steel pipe material and its corresponding mechanical performance indicators.

2. Material hardness

The higher the hardness of the seamless pipe, the stronger its pressure resistance. However, too high hardness will make the seamless pipe prone to cracking, deformation and other defects. Therefore, a balance must be made between hardness and pipe wall thickness to ensure the good pressure resistance of the seamless pipe.

3. Material toughness

The toughness of seamless pipe refers to the ability of the pipe to resist breaking when subjected to stress, and is also one of the important parameters of the pressure resistance of seamless pipe. If the material toughness is too low, it is easy to cause the seamless pipe to break under high pressure.

4. Pipe wall thickness

The pressure resistance of seamless pipe is proportional to the thickness of the pipe wall, that is, the thicker the pipe wall, the stronger its pressure resistance. If you need to improve the pressure resistance of seamless pipe, you can start by increasing the thickness of the pipe wall.

Application of seamless pipe

Seamless pipe is widely used in oil, natural gas, chemical industry, electric power, aviation, aerospace and other fields. The demand for seamless pipe is mainly reflected in pressure resistance, corrosion resistance, high temperature resistance and other aspects. For different application fields, the pressure resistance requirements of seamless pipe are also different, and the corresponding materials and specifications need to be selected.

Summary

As a high-quality pipe, the seamless pipe has good pressure resistance and a wide range of applications. Its pressure resistance is affected by many factors, including material strength, hardness, toughness and pipe wall thickness and so on. For relevant personnel who need to use seamless pipes, they should select the corresponding pipe material and specifications according to their specific application needs.
