Product Description

SS2507 2205 Control Line Tubing S32750 Corrosion Resistance Super Duplex

Control Line refers to small-diameter, high-strength, corrosion-resistant tubing used in subsea and downhole oil and gas applications, typically for controlling subsurface safety valves and other equipment.

Differences Between Super Duplex 2507 and Duplex 2205 in Control Line Applications

Super Duplex 2507:

Composition: Higher chromium, molybdenum, and nickel content than 2205
Strength: Superior tensile and yield strength
Corrosion Resistance: Excellent resistance to pitting and crevice corrosion in harsh environments, particularly in seawater applications
Applications: Ideal for demanding environments like deep-sea control lines where high pressure, temperature, and chloride-induced stress cracking are concerns

Duplex 2205:

Composition: Lower chromium, molybdenum, and nickel content than 2507
Strength: High tensile and yield strength, though lower than 2507
Corrosion Resistance: Good resistance suitable for applications with moderate chloride exposure
Applications: Used in control lines for less aggressive environments compared to 2507
