Seamless pipe vs Welded pipe Cost

Seamless pipe VS welded pipe, which one is more expensive?

1. Production process

Seamless steel pipes are made by directly heating steel billets to a certain temperature and processing through perforation, plugging, hot rolling and other processes, while welded steel pipes are processed into pipes by connecting steel plates through a welding process. Different production processes have different impacts on costs. The production process of seamless steel pipes is precise and the cost is high, so the price is relatively expensive; while the production process of welded steel pipes is relatively simple and the price is more affordable.

2. Quality requirements

The quality requirements of seamless steel pipes are relatively high, and it is necessary to ensure that there are no internal defects, a smooth appearance, and no burrs. However, due to the limitations of the production method, it is difficult to avoid defects such as cracks and pores in the welded parts of welded steel pipes. High-quality seamless steel pipes require higher raw material and precision processing costs, and the price is correspondingly higher.

3. Service life

Seamless steel pipes have higher strength indicators such as compression resistance and tensile strength than welded steel pipes, and have a longer service life.

4. Market demand

Seamless steel pipes are widely used in petroleum, chemical industry, machinery, rail transit and other fields. Due to the particularity of applications and quantity requirements, the price of seamless steel pipes is relatively high. Affected by market competition and market demand, the price of welded steel pipes is relatively low.

Overall, seamless steel pipes are more expensive than welded steel pipes. Because the production process and quality requirements of seamless steel pipes are higher, and the market demand is also more specialized. But this does not mean that welded steel pipes are cheaper in all cases, and they need to be considered comprehensively based on specific circumstances.

Conclusion:

This article analyzes the price difference between seamless steel pipes and welded steel pipes from four aspects: production process, quality requirements, service life and market demand, hoping to provide some inspiration to readers. When purchasing steel pipes, you need to choose based on specific circumstances. Not only should you consider price factors, but also many aspects such as applicability, quality, and use.
