Industry Use Cases

Applications

Oil Refinery & Petrochemical Processing

Oil Refinery & Petrochemical Processing

Seamless 316L/317L and duplex 2205 pipes withstand the corrosive media, elevated temperatures, and high pressures in refinery distillation columns, heat exchangers, and transfer lines — minimizing unplanned shutdowns and extending service intervals.

Pharmaceutical & Biotech Manufacturing

Pharmaceutical & Biotech Manufacturing

Electropolished 316L/316Ti seamless tubes comply with FDA and GMP standards for sterile fluid transfer in pharmaceutical production, bioreactors, and CIP/SIP systems — where zero contamination is mandatory and full traceability is required.

Food & Dairy Processing Plants

Food & Dairy Processing Plants

Hygienic-grade 304/316L welded sanitary tubes safely transport milk, juices, sauces, and beverages — easy to clean, resistant to aggressive cleaning agents, and fully compliant with EHEDG and 3-A Sanitary Standards for high-throughput production.
