3 / 8 * 0.049 Duplex 2205 Capillary Coiled Control Line ASTM A789
TIPTOP produces high integrity and quality controlled stainless steel, duplex and super duplex control line tubing used in demanding subsea umbilical applications. The super duplex seam welded and redrawn product is designed to offer a lower cost alternative with equivalent performance to traditional seamless subsea control lines. Flowline control line tubing is also available for use in pipe-in-pipe bundles.
Control line tubing can be manufactured in lengths including orbital joints up to 15,000m (50,000ft) and is typically in diameters from 1/8" to 1” OD and is used for:
ety critical hydraulic control of sub surface ety valves
Subsea control lines
Downhole control and monitoring in intelligent well completions
Chemical injection using acids, surfactants and methanol
Coiled control line tubing is also used in onshore or topside hydraulic and instrumentation systems where the longer coils result in fewer connections and can increase the integrity of the overall system.
