What is the service life of carbon steel pipe?

Carbon steel tubes are produced from steel ingots or solid round steel that are perforated into capillary tubes and then formed through hot rolling, cold rolling, or cold drawing. These tubes play a crucial role in the steel pipe industry in my country. The performance and longevity of carbon steel tubes depend significantly on the medium and working conditions they are exposed to. There is no definitive lifespan guarantee; even the best alloys can corrode within three months if not properly selected.

Factors Affecting the Use of Carbon Steel Tubes

- Environmental Impact

The environment in which carbon steel tubes are used greatly influences their durability. For instance, tubes used outdoors without an anti-corrosion coating will deteriorate quickly. Conversely, tubes used indoors with protective layers, such as epoxy resin, can have a much longer lifespan.

- Corrosion and Service Life

The service life of carbon steel tubes is directly related to the degree of corrosion they experience, which can be categorized into internal and external corrosion.

Internal Corrosion: This is influenced by the corrosiveness of the medium being transported through the steel pipe.

External Corrosion: This depends on the anti-corrosion treatment applied to the environment surrounding the steel pipe and the quality of maintenance.

To ensure the longevity and efficiency of carbon steel tubes, it is crucial to select the appropriate materials and apply suitable protective coatings based on their intended use and environmental conditions. Proper material selection and maintenance practices are essential to mitigate corrosion and extend the service life of the tubes.
