Hydraulic & Instrumentation Tubes are important components in hydraulic and instrumentation systems to protect and partner with other components, devices or instruments to secure the safe and trouble-free operations of oil and gas plants, petrochemical processing, power generation and other critical industrial applications. Consequently, demand on the quality of tubes is very high.
The major grades manufactured in our mill is mainly in Austenitic and also in Duplex. Our tubes are manufactured in accordance to major International Standards such as ASTM, ASME, EN or ISO. To ensure the high quality of our tubes, we perform 100% Eddy Current Testing and 100% PMI Testing.
