PVDF Encapsulated Control Line Duplex Stainless Steel Capillary Tubing
Meilong Tube manufactures either welded or seamless hydraulic control lines for subsurface applications. Hydraulic control line is available in mainly five materials, varying wall thicknesses, and a wide range of working pressure ratings. The line is supplied on spools to exact length requirements. Upon request, it is pressure tested hydraulically, purged with nitrogen gas, or clean oil liquid, and sealed on both ends prior to shipping.
Welded hydraulic control line is floating plug drawn to ASTM specifications and is available in any length. Material types for hydraulic control lines include stainless steel TP316L which is suitable for sweet to moderately corrosive environments, Duplex stainless steel 2205, Super Duplex stainless steel 2507, nickel alloy Incoloy 825 and Inconel 625 are suitable for severely corrosive environments and high working pressures and temperatures. Control system fluids must be compatible with the environments and operating temperatures of the control line.
Control line encapsulation also is available, where requested, to provide additional crush and abrasion resistance during installation. The encapsulation material should be matched for compatibility with well fluids and temperature requirements.
Encapsulated Control Line
MEILONG offers the encapsulation of control lines to provide increased durability, as well as chemical and corrosion resistance to meet each project’s specialized requirements, we offer different encapsulation types, such as: HDPE (High Density Polyethylene), Santoprene, PVC (Polyvinyl Chloride), Haylar and PVDF (Polyvinylidene Fluoride).
Flatpacks are commonly used when several different lines are terminated at approximately the same depth in the well.
Common applications include intelligent well systems, deep-set chemical injection lines with downhole gauge cable and safety valve lines with shallow set chemical injection lines. For some applications bumper bars are also encapsulated into the flatpack to provide additional crush resistance.
Standard & Approvals
Control Lines are manufactured according to applicable ASTM standards for each specific material.
Tubes can be supplied flushed, filled, and filtered per client requirements and to the appropriate NAS/SAE standards.
