Seamless steel pipe and ordinary steel pipe are two common types of steel pipes, which have some differences in manufacturing process, application field, performance and cost. The following will compare the two steel pipes in detail from the following aspects.
1. Manufacturing process
Seamless steel pipe is made by perforating, rolling, extruding and other processes of steel ingots or billets, and there is no welding process in its production process. Therefore, seamless steel pipe has better sealing and corrosion resistance, and is suitable for special occasions such as high pressure, high temperature and high strength. Ordinary steel pipe is made of steel plates connected by welding process, and its manufacturing process is relatively simple and the price is more affordable, which is suitable for general engineering and construction fields.
2. Application field
Due to its excellent performance, seamless steel pipe is widely used in petroleum, chemical industry, electric power, machinery and other fields, especially in special environments such as high temperature, high pressure and high strength, seamless steel pipe is the preferred material. Ordinary steel pipe is mainly used in general engineering fields such as construction, bridges and roads, and its use is relatively wide.
3. Performance
Seamless steel pipes have better mechanical properties and corrosion resistance, can withstand higher pressures and temperatures, and have longer service life. Ordinary steel pipes have relatively poor performance due to their manufacturing process and material limitations, and are suitable for general engineering and construction fields.
4. Cost
Due to the complex manufacturing process of seamless steel pipes, their production costs are relatively high and their prices are more expensive. Ordinary steel pipes are more affordable due to their simple manufacturing process and relatively low material costs, and are suitable for general engineering and construction fields.
Performance advantages of carbon steel seamless pipes:
1. Good economy
Due to the use of carbon steel as raw material, the cost of carbon steel seamless pipes is relatively low and suitable for large-scale applications.
2. Good processing performance
Carbon steel seamless pipes are easy to cut, bend, weld and other processing operations, which are convenient for on-site construction and maintenance.
3. Moderate strength
On the premise of ensuring safe use, the wall thickness of low-pressure carbon steel pipes can be appropriately thinned to reduce the overall weight and reduce transportation and installation costs.
4. Corrosion resistance
Although the carbon steel pipe itself is not as resistant to corrosion as stainless steel and other materials, its corrosion resistance can be effectively improved through measures such as surface galvanizing and spraying anti-corrosion paint.
5. Wide applicability
Carbon steel seamless pipes are suitable for the transmission of a variety of fluids and gases, including water, oil, natural gas, etc., and are widely used in construction, chemical industry, petroleum, natural gas, agricultural irrigation and other fields.
In summary, there are some differences between seamless steel pipes and ordinary steel pipes in terms of manufacturing process, application field, performance and cost. When choosing to use, you should make comprehensive considerations based on actual needs and usage occasions to select the appropriate type of steel pipe.
