Steel pipes are widely used in many fields, mainly including construction, petrochemicals, electricity, transportation, agriculture, environmental protection, aerospace and shipbuilding. ‌‌

1. In the construction industry, steel pipes are often used in pillars, beams, columns and other parts of building structures, and can withstand large loads. In steel structure buildings, steel pipes are often used in large-span and large-space buildings due to their high strength and seismic resistance. In addition, steel pipes are also used in concrete delivery pipelines and drainage pipelines.

2. In the field of petrochemicals, steel pipes are ideal pipelines for transporting raw materials, products and process media, with high strength, corrosion resistance and high pressure resistance. It is widely used in oil and natural gas pipeline systems, as well as oil well casings and oil pipes.

3. In the power industry, steel pipes are used as efficient and durable conductive materials in the construction of transmission lines and substations, with stable conductivity and mechanical strength. Its good anti-corrosion properties enable it to be used for a long time in harsh environments.

4. In the transportation industry, steel pipes are used for facilities such as highway guardrails, railway rails and subway rail beams. They have the characteristics of high strength, wear resistance and impact resistance, meeting the high requirements of safety and stability.

5. In the agricultural field, steel pipes are used for the supporting structure of greenhouses and water pipes for farmland irrigation systems. Their corrosion resistance, pressure resistance and wear resistance make them have broad application prospects in agriculture.

6. In the environmental protection field, steel pipes are used for pipeline systems in sewage treatment plants and waste incineration plants, as well as structural components for environmental protection equipment such as desulfurization towers and dust collectors.

7. In the aerospace field, steel pipes are used for the supporting structure of aircraft landing gear and the fuel delivery pipeline of rocket engines. Their high strength, light weight and high temperature resistance are crucial in this field.

8. In the shipbuilding field, steel pipes are used for hull structures and engine cooling systems, while meeting the anti-corrosion requirements in the marine environment.
