Stainless Steel Tubing

Super Duplex 2507 Tubing

PAC Stainless Ltd. is the largest stocking distributor of Super
Duplex 2507 tubing in North America. 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 use in aggressive environments such as warm chlorinated seawater
and acidic, chloride containing media. It is widely used in offshore
oil and gas exploration/production and in heat exchangers in petrochemical/chemical processing. The grade is also suitable for hydraulic and instrumentation applications in tropical marine environments.
