Welded Steel Pipe Variety Expansion:

Standard carbon steel wire conduit is a steel pipe used to protect electrical wires in electrical installation projects for industrial and civil construction, equipment installation, and other electrical applications.

2. Seamless Welded Steel Pipe is a type of steel pipe where the weld is parallel to the longitudinal axis of the pipe. It is commonly categorized into metric seamless welded steel pipes, thin-walled welded steel pipes, transformer cooling oil pipes, and so on.

3. The spiral seam submerged arc welded steel pipes for pressure fluid transportation are made from hot-rolled steel strip coils as pipe billets, which are frequently formed into spiral shape at room temperature. They are then welded using the double-sided submerged arc welding method. These pipes are used for the transportation of pressure fluids and feature strong pressure-bearing capabilities and good welding properties. After undergoing rigorous scientific inspections and tests, they are safe and reliable for use. The large diameter pipes offer high transportation efficiency and can also save on the investment in pipeline laying. They are primarily used for transporting oil and natural gas pipelines.

4. The helical seam high-frequency welded steel pipes for pressure fluid transportation are made from hot-rolled steel strip coils as billets, formed into pipes through normal temperature spiral forming, and welded using high-frequency butt welding technology. These pipes are designed for the transportation of pressure fluids. The steel pipes have strong pressure-bearing capacity, good plasticity, and are easy to weld and shape. After rigorous and scientific inspections and tests, they are safe and reliable for use. The large diameter of the pipes ensures high transportation efficiency and can save on pipeline installation costs. They are primarily used for laying pipelines for the transportation of oil, natural gas, and other fluids.

5. Spiral seam submerged arc焊接钢管, commonly used for the transportation of low-pressure fluids, are manufactured from hot-rolled steel strip coils into billets, then formed into pipes through cold-rolled spiral forming. They are produced using double-sided active submerged arc welding or single-sided welding processes, and are designed for the transportation of fluids like water, gas, air, and steam at low pressure.

6. Standard low-pressure fluid transportation spiral seam high-frequency welded steel pipes are manufactured from hot-rolled steel strip coils, which are shaped into pipes through normal temperature spiral forming. They are焊接 using high-frequency butt welding technique for standard low-pressure fluid transportation spiral seam high-frequency welded steel pipes.

7. Pile spiral-welded steel pipes are produced by rolling hot-rolled steel strip into a billet, frequently cold-rolled into spiral shape, and then made by double-sided submerged arc welding or high-frequency welding. They are used for the foundation piles of civil engineering structures, docks, bridges, and other applications.
