How To Choose The Thickness of Carbon Steel Seamless Pipe?

Carbon steel seamless pipe is a pipe made of carbon steel raw materials through a series of processing processes (such as hot rolling, cold drawing, etc.). Its biggest feature is that there is no welding seam on the pipe body. Compared with welded pipes, this seamless structure ensures the uniformity and continuity of the pipe as a whole, thus having higher pressure resistance, wear resistance and corrosion resistance. These excellent characteristics make it widely used in harsh environments such as machinery manufacturing, oil and gas transportation, chemical equipment, and high temperature and high pressure.

Given that carbon steel seamless pipes play a key role in such complex and demanding working environments, it is particularly important to reasonably select their thickness. The thickness selection of carbon steel seamless pipes should consider the use scenario and the pressure they bear. Generally, choosing an appropriate thickness can improve the service life and safety of seamless pipes.

Principles of thickness selection

The thickness selection of carbon steel seamless pipes should consider their use scenarios and pressure they bear.

If the thickness is too thin, it will not only be unable to withstand greater pressure, but also be prone to explosion accidents; if the thickness is too large, it will waste materials, increase costs, and increase the weight of seamless pipes. Therefore, the thickness should be selected reasonably according to the specific situation.

Thickness measurement

The thickness of carbon steel seamless pipe is usually measured with a thickness gauge. When measuring, the accuracy of the measuring instrument and the accuracy of the measuring position should be ensured. In order to ensure accurate and reliable data, multiple measurements should be taken from different places, and the average value should be taken as the final thickness value.

Reference value of thickness

The following are some common specifications of carbon steel seamless pipes and reference values of corresponding thickness:

1. Pipes with an outer diameter of 32mm, the wall thickness is generally 3.5mm or 4mm.

2. Pipes with an outer diameter of 50mm, the wall thickness is generally 3.5mm, 4mm or 5mm.

3. Pipes with an outer diameter of 108mm, the wall thickness is generally 4.5mm or 5.5mm.

Other precautions

1. During installation and use, attention should be paid to the protection and maintenance of seamless pipes, and leaks should be checked and repaired in time and the inside of the pipe should be cleaned to extend the service life of seamless pipes. The parts connected to the pipe flange should ensure sealing to prevent leakage.

2. Choose seamless pipes produced by regular manufacturers to ensure their quality and safety.

3. When purchasing, check the manufacturer's qualifications and product certificates to confirm product quality and eligibility. Especially for pipes used in high-risk scenarios such as boiler tube.

Conclusion

Choosing the appropriate thickness can improve the service life and safety of carbon steel seamless pipes. When choosing, you should consider its usage scenario and pressure resistance. When measuring, you should ensure the accuracy of the measuring instrument and the accuracy of the measuring position. Choose seamless pipes produced by regular manufacturers to ensure their quality and safety.
