Are Mild Steel Tubes Used in Gas Pipelines?

Yes, gas pipelines use the mild steel tube. The following will give you a detailed introduction to why mild steel tubes are used.

Material of gas pipelines

Gas pipelines are mainly divided into two types: plastic pipes and steel pipes. Plastic pipes are suitable for certain low-pressure and short-distance transmission occasions, but their overall application range is not as wide as that of steel pipes. Steel pipelines are pipeline systems composed of various heavy steel pipes, connectors, valves, accessories, etc. Steel pipelines can withstand large internal and external pressures and adapt to various complex working conditions. After anti-corrosion treatment, they are suitable for long-distance transmission and harsh environments. The structural design ensures that the pipeline has good sealing performance during the transmission process and reduces the risk of leakage. It is used in many aspects such as urban gas transmission and distribution stations, regional gas transmission stations, and gas supply stations of enterprises and institutions.

Advantages and disadvantages of mild steel tubes

Mild steel tube refers to carbon steel pipe made of low-carbon steel and usually have a carbon content of less than 0.3%. Low-carbon steel is a steel with a low carbon content, good plasticity and toughness. Due to its excellent physical properties and processing properties, it occupies an important position in industrial production.

1. Advantages

Strong corrosion resistance: After anti-corrosion treatment, it can effectively resist the erosion of chemical media in harsh environments.

Excellent processing performance: Good cutting and welding performance, easy for secondary processing and on-site installation.

Cost advantage: Low production cost, obvious economic benefits, suitable for large-scale application.

2. Disadvantages and countermeasures

Rust problem: Local corrosion may occur after long-term use, and regular inspection and maintenance are required.

Hydrogen embrittlement risk: Hydrogen embrittlement may occur under certain conditions. It is recommended to adopt protective measures and strengthen daily monitoring during use.

Why do gas pipelines use mild steel tubes

Gas pipelines need to meet the characteristics of strong pressure resistance, corrosion resistance, and good sealing. Mild steel tubes are a type of pipe with high strength and good corrosion resistance. In the construction of gas pipelines, mild steel tubes are one of the most commonly used pipes. Why do gas pipelines use mild steel tubes?

1. Strong pressure resistance

Gas pipelines need to withstand internal and external high pressure for a long time. The high strength of mild steel tubes can effectively ensure the safety of the pipeline.

2. Corrosion resistance

Mild steel tubes have good corrosion resistance and extend service life under proper protection.

3. Excellent sealing

The manufacturing process of mild steel tubes ensures that there are no welds or joint defects, reducing the risk of gas leakage.

4. Good plasticity and weldability

Easy to process and install, and can meet various on-site construction needs.

5. Economical and practical

Compared with other high-alloy steels, mild steel tubes have lower costs, but can fully meet performance requirements in most gas transmission occasions.

Summary

In short, it is a common practice to use mild steel tubes for gas pipelines, because mild steel tubes have good strength and corrosion resistance, which can well meet the use requirements of pipelines. However, since mild steel tubes are prone to rust and hydrogen embrittlement, it is necessary to pay attention to strengthening maintenance and care during use.
