Diversified assortment of welded pipes: Unlocking unlimited possibilities for global industrial applications

In the global industrial market, welded pipes are widely used in various engineering projects as an efficient and economical pipeline solution. In order to meet the specific needs of different industries and customers, welded pipes are designed into various types, each of which plays a key role in its specific application scenario. This article will introduce the diversified classification of welded pipes in detail to help global customers better understand and choose welded pipe products that suit their needs.

1. Classification by purpose

General welded pipes: Mainly used to transport low-pressure fluids such as water and gas. This type of welded pipe is usually made of steel such as Q195A, Q215A, and Q235A. The delivery length is usually 4-10 meters, and it can be delivered in fixed length or multiple lengths as required.

Galvanized welded pipe: In order to improve the corrosion resistance of steel pipes, general welded pipes are galvanized to form galvanized welded pipes. This type of welded pipe performs well in humid or corrosive environments and is often used in outdoor facilities or occasions where additional protection is required.

Wire casing: Also known as ordinary carbon steel electric welded steel pipe, it is mainly used to protect wires in concrete structures and power distribution projects. This type of welded pipe has a thinner wall and is often coated or galvanized to ensure electrical safety and long-term durability.

Spiral welded pipe: It is made by rolling low-carbon carbon structural steel or low-alloy structural steel strip into a pipe blank at a certain angle and then welding it. Spiral welded pipe is suitable for the production of large-diameter pipes and is often used for the transportation of pressurized fluids such as oil and natural gas.

Special-shaped welded pipe: Including various non-circular welded pipes such as square, rectangular, and cap-shaped, mainly used in the manufacture of furniture, lamps, steel structures, etc.

2. Classification by production method

Arc welded pipe: manufactured by arc welding process, suitable for the production of welded pipes of various materials.

Resistance welded pipe: divided into high-frequency and low-frequency types, the edge of the pipe blank is heated to a molten state by resistance heat and then pressed together, which is suitable for the production of thin-walled welded pipes.

Gas welded pipe: welding using gas flame, suitable for small welded pipes or special materials.

Furnace welded pipe: welding in a furnace, suitable for large-scale and high-efficiency welded pipe production.

3. Classification by weld seam

Straight welded pipe: The weld seam is parallel to the longitudinal direction of the steel pipe, suitable for low-pressure fluid transportation and general structural purposes.

Spiral welded pipe: The weld seam is spiral, suitable for large-diameter, high-pressure fluid transportation, such as oil and natural gas pipelines.

4. Classification by cross-sectional shape

The cross-sectional shapes of welded pipes are diverse, including round, square, oval, triangle, hexagon, diamond, etc., to meet the needs of different application scenarios.

5. Classification by wall thickness

Welded pipes can be divided into thin-walled welded pipes and thick-walled welded pipes according to wall thickness. Thin-walled welded pipes are mainly used for lightweight structures such as furniture and lamps, while thick-walled welded pipes are suitable for high-pressure fluid transportation and heavy structures.

6. Classification by end shape

The end shape of the welded pipe can be round or special-shaped (such as square, flat, etc.) to adapt to different connection methods and installation requirements.

The diversified classification of welded pipes provides unlimited possibilities for global industrial applications. Whether it is construction, oil, natural gas, electricity, communications or machinery manufacturing, you can find welded pipe products that meet their needs. When choosing a welded pipe, be sure to consider factors such as its application, production method, weld type, cross-sectional shape, wall thickness and end shape to ensure that the selected product can meet your specific needs.
