    Inconel Alloy UNS N06625 Precision Coil Tubing For Oil / Gas Fields

    Inconel Alloy UNS N06625 Precision Coil Tubing For Oil / Gas Fields


    Description

    Inconel Alloy N06625 is an austenitic nickel / chromium / molybdenum / niobium alloy (see Table 1 on reverse). The high alloy content enables Inconel alloy N06625 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.


    Application

    Oil and Gas: Subsea

    Sub-Surface Safety Valves (SSSV) / Umbilicals: Tubes filled with Hydraulic Fluid which run from floating platform or FPSO to the well head on the sea floor.


    Oil and Gas: Downhole

    Downhole Control Lines: Tubes running from above ground surface controls into a downhole well to the location of the well’s safety valve.


    Geothermal

    Application

    Inconel Alloy N06625 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.


    Standards and Specifications

    Alloy N06625 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.


    Manufacturing Process and Resultant Properties

    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.


    Nondestructive Testing (NDT)

    Eddy current testing (ECT) is performed on the longitudinally seam welded tubing and strip splice welds in the as-heat treated condition. Those strip splice welds detected by ECT. Yield pressure hydrostatic testing is performed on the heat treated tubing at final size.

    Since 1999, Meilong Tube Co., Ltd. has produced long coils of stainless steel and high nickel alloy tubing for numerous oil and gas applications, including hydraulic power, monitoring and control equipment, instrumentation, injection lines, down-hole safety valve control, subsea umbilical applications. Unique manufacturing capabilities and processes allow Meilong to produce the longest continuous length control line tubing available in stainless steels and high nickel alloys.


    Our coiled tubing is available in a number of high performance corrosion resistant stainless steels and high nickel alloys, including 300 series, Incoloy, Inconel, capable of withstanding a variety of severe environmental conditions.


    We specialize in manufacturing small diameter tubing ranging from 0.125 inch to 1 inch outside diameter (3.18mm to 25.4 mm) and a variety of wall thickness. All tubing is level wound coiled on various size spools, and products are tested and evaluated for specific applications before delivery. Our engineering staff welcome the opportunity to work with customers to solve special problems.


    Meilong’s seamless control line tubing is drawn from seamless extruded tube hollows to ensure absolute product safety and reliability. Our seamless line tubing is one continuous length of tubing, completely free of any welded joints or seams. Long length coils reduce installation time and costs by eliminating the need for excessive joints preparation and fittings. Elimination of excessive fittings increase reliability and assures a leak-free system. We are capable of 100% hydrotesting each coil.


    In meeting customer’s requirements, our tubing can be encapsulated in various materials such as thermalplastics, nylon and PVDF. Coiled seamless control line tubing offers many advantages to installers of hydraulic or pneumatic lines on offshore platforms and onshore refineries. It offers unmatched safety and reliability, while at the same time reducing the frequency of costly joint connections. Close tolerance control during manufacturing assures easy insertion and connection to fittings due to tubing’s inherent ductility.


    Downhole hole & umbilical tubing

    Our long length seamless coils are used extensively for chemical injection and hydraulic control in subsea and onshore wells. The long length minimizes the number of orbital welds which reduces the potential for weld-related defects and failures. Additionally, our coils have an extremely clean and smooth ID surface that is ideal for hydraulic and chemical injection systems. Seamless stainless steel coils offer short hydraulic response time, greater collapse strength, and elimination of methanol permeation.


    Vacuum annealing

    Meilong takes special care during manufacturing to assure ID and OD cleanliness of control line tubing. Vacuum annealing insures volatility of metallic oxides and removal of any residual degreasing solvents or drawing lubricants. Vacuum annealing our stainless steel tubing insures a bright, cosmetically appealing surface as well as excellent mechanical properties.


    Meilong commitment to quality excellence

    From the time an order is received, sent through the production process, completed, and finally shipped, many levels of inspection occur to reinforce Meilong’s Quality Policy. The job of ensuring quality products extends as far as our machine operators. Meilong operators take ownership over material processed at their stations by measuring for dimensional accuracy and conducting a visual inspection of every piece.
