Welding 0.083" ASTM Duplex 2507 Hydraulic Coiled Tubing

Product Description

Customized High Precision Duplex 2507 Hydraulic Coiled Tubing

2507 Super Duplex is a high-alloy duplex stainless steel with a PRE (Pitting Resistance Equivalent) value of minimum 42.5. The grade is characterized by very good chloride corrosion resistance, combined with very high mechanical strength. It is particularly suited for aggressive environments such as warm chlorinated seawater and acidic, chloride containing media. It is widely used in offshore oil and gas exploration and in heat exchangers in petrochemical  processing. It's also suitable for hydraulic and instrumentation applications in tropical marine environments.
