1/8" OD SS Hydraulic Control Line Tubing Capillary Tubes
HAOSTEEL is one of the most professional manufacturer and supplier of stainless steel Tube.Stainless steel tube can be divided into seamless tube and welded tube according to production mode. Seamless tube can be divided into hot rolled tube, cold rolled tube, cold drawn pipe and extruded tube.The welded pipe is divided into straight welded pipe and spiral welded tube.
Description
The hydraulic control line tubing is another name of the capillary tubes, mainly used to measure oil and gas subsurface capillary pressure. Temperature and pressure sensors (also called permanent downhole gauge, usually nitrogen bottles) kilometers deep into the reservoir and oil and gas well production string and then into 1/8" hydraulic control line (capillary tube). Temperature and pressure sensors are always connected to the surface of the fluorescent display, and therefore the downhole temperature and pressure may be transmitted through the capillary downhole surface, instantaneous temperature and pressure downhole oil and water may also be transmitted to the surface. Gas layer is formed by screen surface of the display, in order to achieve downhole temperature and pressure to achieve real-time monitoring of downhole temperature and pressure and also to control the pressure safety valve on the surface.
