Inconel Alloy 625 Encapsulated Control Line Max Length 10000 Meters
Inconel Alloy 625 seam welded pressure tubing in the heat treated and cold worked condition is typically used in oil and 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. The tubing is frequently supplied as 5,000 to 35,000 ft. coils on a wooden reel, depending on size.
Inconel Alloy 625 is an austenitic nickel / chromium / molybdenum / niobium alloy (see Table 1 on reverse). The high alloy content enables Inconel alloy 625 to withstand severe aqueous corrosion environments. High molybdenum content (8.0 to 10.0%) makes the alloy very resistant to chloride pitting and crevice corrosion. High nickel content (58.0% min.) provides relative freedom from chloride ion induced stress-corrosion cracking. Alloy N06625 has shown excellent 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 4d in hydrogen sulfide containing environments for oil and gas production.

High quality polymeric jackets/encapsulations provide added protection
Core tubing is evaporated with the latest thermoplastic elastomeric compounds designed to outlast the life of most project tubing installations by reducing the possibility of corrosion and mechanical damage. They can stand up to a wide range of chemical inhibitors and seawater. Most jackets are manufactured from fire retardant, all-weather, abrasion-resistant compound, designed to remain strong and flexible through wide ranges of temperatures and pressures.
Standards and Specifications
Alloy 625 Tubing with Enhanced Properties
ASTM B704, Standard Specification for Welded UNS N06625, UNS N06219, and UNS N08825 Alloy Tubes, except in the as-cold worked condition
ASTM B444, Standard Specification for Alloy UNS N06625 Seamless Pipe And Tube
Meets the material limits for annealed and cold-worked, solid solution, nickel-based alloys listed in ISO 15156-3 for material type 4d in Table A.14.
Welded & Redrawn Tubing
Strip splice welds join lengths of cold rolled strip to enable long lengths between orbital welds (greater than 14,500 ft 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 first sunk to an intermediate outside diameter, heat treated, and make the same process to obtain the desired size.
Seamless & Redrawn Tubing
Seamless extruded tube hollows are drawn or drawn / sunk to final size to produce seamless tubing coils 500 to 2,000 ft. long, depending upon the size. The tubing is heat treated and joined by orbital welding to achieve the desired length. The final material condition of the tubing is heat treated.
