Product Description

S31803 High Ductility Duplex 2205 SS Stainless Steel Coiled Tubing


S31803 is commonly called 2205 and is the most widely used duplex stainless steel. It contains approximately 22% chromium, 5% nickel, and 3% molybdenum.It combines high strength, ductility, and hardness with resistance to corrosion, stress corrosion cracking, and erosion. 




Duplex stainless S31803 seamless tubing is mainly 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 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 such as 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 are available on a wooden or steel reel, depending on size.
