ASTM B444 Geothermal Tubing Hydraulic Control Line Annealed

ASTM B444 Geothermal Tubing Hydraulic Control Line Annealed

Product Description:

Meilong Tube's downhole control lines are used primarily as communication conduits for hydraulically operated downhole devices in oil, gas, and water-injection wells, where durability and resistance to extreme harsh conditions are required.
These lines can be custom configured for a variety of applications and downhole components. All encapsulated materials are hydrolytically stable and are compatible with all typical well completion fluids, including high-pressure gas. The material selection is based on various criteria, including bottomhole temperature, hardness, tensile and tear strength, water absorption and gas permeability, oxidation, and abrasion and chemical resistance.
Control lines have undergone extensive development, including crush testing and high-pressure autoclave well simulation. Laboratory crush tests have demonstrated the increased loading under which encapsulated tubing can maintain functional integrity, particularly where wire-strand “bumper wires” are used.
Duplex 2507 is a super duplex stainless steel designed for applications which demand exceptional strength and corrosion resistance. Alloy 2507 has 25% chromium, 4% molybdenum, and 7% nickel. This high molybdenum, chromium and nitrogen content results in excellent resistance to chloride pitting and crevice corrosion attack and the duplex structure provides 2507 with exceptional resistance to chloride stress corrosion cracking.
Usage of Duplex 2507 should be limited to applications below 600° F (316° C). Extended elevated temperature exposure can reduce both the toughness and corrosion resistance of alloy 2507. Duplex 2507 possesses excellent mechanical properties. Often a light gauge of 2507 material can be used to achieve the same design strength of a thicker nickel alloy. The resulting savings in weight can dramatically reduce the overall cost of fabrication.
Corrosion Resistance 2507 Duplex is highly resistant to uniform corrosion by organic acids such as formic and acetic acid. It is also highly resistant to inorganic acids, especially if they contain chlorides. Alloy 2507 is highly resistant to carbide-related intergranular corrosion. Due to the ferritic portion of the duplex structure of the alloy it is very resistant to stress corrosion cracking in warm chloride containing environments. Through additions of chromium, molybdenum and nitrogen localized corrosion such as pitting and crevice attack are improved. Alloy 2507 has excellent localized pitting resistance.

Features:

Features:
Control lines can be delivered in orbital-weld-free lengths up to 40,000 ft (12,192 m) to maximize reliability.
We provide a wide range of single, dual, or triple flat-packs. Flat-packs can be combined with downhole electrical cables and/or bumper wires for easier operation and handling during deployment.
Advantages:
The welded-and-plug-drawn production method ensures a smooth, round tube to allow long-term metal sealing of terminations.
Benefits:
Encapsulation materials are selected to suit well conditions, ensuring longevity and reliability.

Technical Parameters:

Applications:

For chemical injection, capillary coiled alloy tubing is used for a variety of applications.
Hydraulic control lines for subsea safety valves are often specialized for their use, and they come in either bare or encapsulated versions.
Velocity strings, work strings, and steel tube umbilicals all make use of tubing and can be used in different applications.
Finally, geothermal coiled alloy tubing is used to transfer energy from geothermal sources and can be used surprisingly efficiently.
