Product Description

1 / 8 Seamless Hydraulic Control Line Capilary tube Super Duplex 2507 UNS S32750


1/8" hydraulic control line (capillary) WT 0.02", 0.028" and 0.035"


1/8" hydraulic control line, also called capillary tube, is mainly used in oil and gas underground capillary pressure testing. The temperature and pressure sensor (also called permanent downhole type pressure gauge, typically nitrogen cylinder), together with the oil and gas well production string will be put into thousands of meters of underground oil and gas layer. Then 1/8" hydraulic control line (capillary) will be used to connect temperature and pressure sensor with the fluorescent display of the ground. So the downhole temperature and pressure can be reached the ground through the capillary. Through the ground display screen, people can get the instantaneous temperature and pressure in underground oil and gas layer, so as to monitor the downhole temperature and pressure in real time.


It can also be used for pressure control of surface safety valve and other surface valves, as well as various connecting lines of instrument control system for oil and gas field drilling and oil production large-scale equipment.
