The production of large-diameter pipes must comply with strict quality standards to ensure both reliability and durability. Whether round or square (circular or rectangular cross-section), these pipes are designed to resist wear and corrosion caused by external agents such as weather, pollution, mechanical impact, or chemical exposure.
To ensure objective and verifiable quality, large-size pipes undergo rigorous tests and inspections, such as:
- Radiographic examinations
- Non-destructive testing
- Eddy current testing
- Dye penetrant inspection
- Ultrasonic testing
If all checks are passed, internationally recognized certification is issued.
Production results also depend on the quality of the materials, especially the steel used.
Available processing options include polishing, conical reduction, passivation, satin finishing, pickling and weld bead removal. Precision in every step is essential to achieve optimal performance with cutting-edge technologies.
In terms of use, large-diameter 316 stainless steel pipes are primarily used in industrial sectors: petrochemical, food, pharmaceutical, extraction, manufacturing and chemical industries.
This highlights the growing importance of large-diameter pipes in today’s economic context, whether welded, electrowelded, polished, seamless, raw, satin or rolled—as long as they comply with AISI standards and offer long-term reliability.
