Comprehensive analysis of seamless steel pipe 325 * 8 (GB/T6479-2013) for high-pressure fertilizer pipeline No. 20

1、 Material and chemical composition

The seamless steel pipe used for high-pressure fertilizer pipeline No. 20 is mainly made of No. 20 steel, which is a high-quality carbon structural steel. Its chemical composition mainly includes elements such as carbon (C), silicon (Si), manganese (Mn), phosphorus (P), sulfur (S), etc. The specific content standards are executed according to the GB/T6479-2013 standard. This type of steel has good mechanical and processing properties, making it suitable for manufacturing pipelines that withstand high pressure and impact.

2、 Performance characteristics

High strength and toughness: The seamless steel pipe used for high-pressure fertilizer pipeline No. 20 has high tensile strength and yield strength, and can withstand large pressure and impact forces. At the same time, it also has good toughness and can resist the occurrence of fracture and deformation to a certain extent.

Strong corrosion resistance: Due to the production of various corrosive media during fertilizer production, seamless steel pipes need to have good corrosion resistance. The steel pipe has undergone special treatment to form a protective film on the surface, which can effectively resist the erosion of corrosive media.

Convenient connection: The steel pipe is connected by welding or threading, making installation convenient and fast, which can significantly shorten the project cycle.

Long service life: Due to its excellent corrosion resistance and mechanical properties, the steel pipe has a longer service life, reducing the frequency of maintenance and replacement.

3、 Purpose

The seamless steel pipe used in the No. 20 high-pressure fertilizer pipeline is mainly used for conveying high-temperature and high-pressure fluids in fertilizer production equipment. In the process of fertilizer production, these pipelines need to withstand the erosion of high temperature, high pressure, and corrosive media, so high-quality seamless steel pipes are needed to ensure the stability and safety of production. In addition, the steel pipe can also be applied in fields such as shipbuilding, environmental protection equipment, and energy.

4、 Usage environment

This steel pipe is suitable for conveying high-temperature and high-pressure fluids in fertilizer production equipment. In these environments, pipelines need to withstand the erosion of high temperature, high pressure, and corrosive media, thus requiring high strength, high toughness, and corrosion resistance.

5、 The impact of domestic and international economic environment on fertilizer pipes

Global demand for fertilizers is increasing: With the rise in global food prices and the increasing willingness of farmers to plant, global demand for fertilizers continues to increase. This has promoted investment and construction of fertilizer production equipment, thereby increasing the demand for seamless steel pipes for high-pressure fertilizer pipelines.

The price difference between domestic and international markets affects exports: Due to the implementation of fertilizer supply and price stability policies in China, there is a significant price difference between international and domestic prices, which makes export enterprises profitable. This has promoted the production and export of domestic fertilizer pipelines, further promoting the development of the industry.

Environmental policies affect production costs: In the high-pressure environment of environmental protection in China, the prices of fertilizer raw materials continue to rise, increasing the cost of fertilizer production. However, this also increases the demand for production equipment such as fertilizer pipelines, as companies need to improve production efficiency to reduce costs.

Supply side reform affects production: With the advancement of supply side reform, the overall fertilizer production in the country has decreased. However, this does not mean that the demand for fertilizer pipelines will decrease, as the remaining production enterprises will focus more on improving production efficiency and product quality, thereby increasing the demand for high-quality seamless steel pipes.

In summary, the seamless steel pipe (GB/T6479-2013) used for high-pressure fertilizer pipeline No. 20 has broad application prospects and market demand in the field of fertilizer production. At the same time, the domestic and international economic environment has also had a certain impact on the development of the industry.
