Seamless steel pipe and traditional pipe performance differences

There are some performance differences between seamless steel pipe and conventional pipe, mainly in the following aspects:

1. Full-size continuity: Seamless steel pipe is manufactured through processes such as hot-rolling or cold-drawing, and therefore has full-size continuity without welded joints. In contrast, conventional tubes (such as welded steel tubes) typically require welded joint connections, which can present weld weaknesses and risk of fracture.

2. Compressive performance: Since seamless steel pipe has no welded joints, the overall structure is stronger and more consistent, with higher compressive performance. Whereas the welded joint portion of conventional pipes may have weaknesses, seamless steel pipes may be more suitable for application scenarios that are subjected to high pressure or shock loads.

3. Surface finish: Seamless steel pipe has relatively smooth internal and external surfaces, and is rust-proof, which effectively reduces the adhesion of corrosive and obstructive substances and improves the efficiency of fluid transportation. The surface of the traditional pipe may have weld tumor, oxide layer and other uneven conditions, which have a certain impact on fluid transportation and obstruction accumulation.

4. Corrosion resistance: seamless steel pipe can be selected according to the use of environment and requirements of different materials, has good corrosion resistance. For example, stainless steel seamless steel pipe has strong corrosion resistance in wet or corrosive environments. While traditional pipes (such as ordinary steel pipes) may require anti-corrosion treatment to improve corrosion resistance.

5. Production process and cost: The production process of seamless steel pipe is relatively complex, including steps such as hot rolling, cold drawing and hot expanding, so its production cost is relatively high. While the production process of traditional pipes (such as welded steel pipe) is relatively simple and low cost.

The right pipe needs to be selected based on specific application scenarios and needs, taking into account factors such as performance, cost, corrosion resistance, pressure requirements, etc. for evaluation and selection.
