1.seamless vs welded pipe？
The pressure bearing capacity and strength of seamless steel pipe are higher than those of ERW welded steel pipe. The weld of welded steel pipe is its weak link, and its quality will affect the overall performance.
2.What are the main application areas of seamless steel pipes?
Widely used in petroleum, chemical industry, machinery manufacturing, aerospace and other fields, especially suitable for high pressure and high temperature environments.
3.How to choose high-quality seamless steel pipes?
- Check the surface for cracks, folds and other defects
- Measure whether the dimensional tolerance meets the standards
- Ask the supplier to provide material reports and test certificates
