    Alloy 2205 S32205 Capillary Coiled Steel Tubing Seam Welded / Bright Annealed

    Alloy 2205 seam-welded pressure tubing

    Alloy 2205 is a duplex stainless steel. When properly heat treated, the microstructure consists of a nearly equal mixture of the austenitic and ferrite phases. This two-phase microstructure produces a fine grain size which increases the yield strength. In the final heat treated condition, alloy 2205 can achieve a yield strength approximately twice that of austenitic alloys such as 316L, 825 and 625 which must be cold worked to achieve comparable yield strengths. Duplex stainless steels are often classified as lean, conventional, super or hyper based upon their pitting resistance equivalent (PRE or PREN). Various PRE formulas are used to rank an alloy’s resistance to chloride pitting corrosion based upon its composition. Alloy 2205 typically has a PRE of 36 and is considered a conventional duplex stainless steel. Alloy 2205 is often selected for use in oil and gas production environments based upon its higher strength and resistance to pitting, crevice and stress corrosion cracking in chloride containing environments. Consult ISO 15156-3, Table A.24 for the limits regarding the use of alloy 2205 in hydrogen sulfide containing environments for oil and gas production. MEILONG TUBE uses expert system software to assist customers in their selection of alloys for oil and gas environments.


    Alloy 2205 seam welded pressure tubing in the heat treated condition is typically used in oil and natural gas wells for chemical injection applications. In such applications, it is commonly referred to as capillary tubing and is free-hanging (self-supporting) inside the production casing. The chemicals being injected are often used to enhance production flow rates, inhibit corrosion or scaling and/or de-water. However, the tubing can also be used for control line tubing applications including hydraulically actuated surface-controlled subsurface safety valves. For control line applications, the tubing is generally deployed by strapping it to the outside of the production casing. The tubing is frequently supplied as 5,000 to 35,000 ft. Coils on a wooden or steel reel, depending on size.
