Product Description

Seamless Incoloy 825 Tubing , Alloy 825 Tubing For Chemical Injection


Description
Incoloy Alloy UNS N08825 is a titanium-stabilized austenitic nickel-iron-chromium alloy with additions of molybdenum and copper. The chemical composition of the alloy is listed in Table 1. The alloy is characterized by good resistance to stress-corrosion cracking due to its nickel content (38.0 to 46.0) and satisfactory resistance to pitting and crevice corrosion. Alloy 825 has shown good corrosion resistance in oil and gas production environments containing hydrogen sulfide, carbon dioxide and chlorides. Consult ISO 15156-3, Table A.14 for the limits regarding material type 4c in hydrogen sulfide containing environments for oil and gas production.

Application
Alloy UNS N08825 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 reffered 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. The tubing is frequently supplied as 5,000 to 35,000 ft. coils on a wooden reel, depending on size.
 
 
Manufacturing Process and Resultant Properties
Strip splice welds join lengths of cold rolled strip to enable long lengths between orbital welds (greater than 14,500 between orbital welds is achievable).
 
The strip is formed into a tubular cross section and longitudinally seam welded using the gas tungsten arc (GTAW) process. The tubing is plug-redrawn to an intermediate outside diameter, heat treated, and make the same process circulation to achieve the desired size and length.
 
Nondestructive Testing (NDT)
Eddy current testing (ECT) is performed on the longitudinally seam welded tubing and strip splice welds at intermediate size in the as-heat treated condition. Those strip splice welds detected by ECT at intermediate size in the as-heat treated condition. Yield pressure hydro static testing is performed on the heat treated tubing at final size.
