Types and uses of welded steel pipes

1. Welded steel pipe for low-pressure fluid transportation is also called a general welded pipe, commonly known as clarinet. It is a welded steel pipe for conveying water, gas, air, oil and heating steam, and other generally lower pressure fluids and other purposes.

2. Galvanized welded steel pipe for low-pressure fluid transportation is also called galvanized welded steel pipe, commonly known as a white pipe. It is a hot-dip galvanized (furnace welded or electric welded) pipe used for conveying water, gas, air oil, heating steam, warm water, and another general lower pressure fluids or other purposes.

3. Ordinary carbon steel wire casing is a steel pipe used to protect wires in electrical installation projects such as industrial and civil construction and installation of machinery and equipment.

4. Straight seam electric welded steel pipe is a steel pipe whose weld seam is parallel to the longitudinal direction of the steel pipe. Usually divided into metric electric welded steel pipe, electric welded thin-walled pipe, transformer cool oil pipe, and so on.

5. Spiral seam submerged arc welded steel pipe for pressure-bearing fluid transportation is a hot-rolled steel strip as a tube blank, which is often spirally formed by double-sided submerged arc welding and is used for pressure-bearing fluid transportation. The steel pipe has strong pressure bearing capacity and good welding performance. Mainly used in pipelines for transporting oil and natural gas.

6. Spiral seam high-frequency welded steel pipe for pressure-bearing fluid transportation is a hot-rolled steel strip as a tube blank, which is often spirally formed by high-frequency lap welding and is used for pressure-bearing fluid transportation. Welded steel pipe. Mainly used to lay pipelines for transporting oil and natural gas.

7. The spiral seam submerged arc welded steel pipe for general low-pressure fluid transportation is made of hot-rolled steel coils as tube blanks, which are often spirally formed by double-sided automatic submerged arc welding or single-sided welding. It is used for water, gas, and air. Submerged arc steel pipe for general low-pressure fluid transportation such as steam and steam.

8. Spiral seam high-frequency welded steel pipe for general low-pressure fluid transportation is a hot-rolled steel strip as a tube blank, which is often spirally formed by high-frequency lap welding. It is used for general low-pressure fluid transportation.

9. Spiral welded seam steel pipes for piles are made of hot-rolled steel strip coils as piping billets, which are often spirally formed by double-sided submerged arc welding or high-frequency welding. They are used for foundation piles of civil construction structures, docks, bridges, etc.
