ASTM A269 316L stainless steel seamless coiled tubing hydraulic control line
MEILONG TUBE provides either welded or seamless hydraulic control lines for subsurface applications. Hydraulic control line is available in 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 clean oil, and sealed on both ends prior to shipping.
Welded hydraulic control line is sunk-drawn to ASTM specification A-269 and is available in any length. Seamless hydraulic control line is available in length to 500 ft (152 m). Lengths greater than 500 ft (152 m) are joined by orbital welding, which also meets ASTM specification A-269.
Material types for hydraulic control line include TP316L stainless steel, Incoloy 825, and Inconel 625. Control line made of TP316L stainless steel is suitable for sweet to moderately corrosive environment. 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 temperature 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.
