A coiled capillary tubing operation is normally performed through the drilling derrick on the oil platform， which is used to support the surface equipment， although on platforms with no drilling facilities a self-supporting tower can be used instead. The major application of capillary tubing is in the instrument and controls field， where it's used to transmit pressure changes over great distances by means of gases or liquids. For coiled tubing operations on sub-sea wells a mobile offshore drilling unit (MODU) e.g. semi-submersible， drillship etc. has to be utilized to support all the surface equipment and personnel， whereas wireline can be carried out from a smaller and cheaper intervention vessel. Onshore， they can be run using smaller service rigs， and for light operations a mobile self-contained coiled tubing rig can be used.

In the oil and gas industries， coiled tubing refers to a very long metal pipe， normally 1 to 3.25 in (25 to 83 mm) in diameter which is supplied spooled on a large reel. It is used for interventions in oil and gas wells and sometimes as production tubing in depleted gas wells. Coiled tubing is often used to carry out operations similar to wirelining. The main benefits over wireline are the ability to pump chemicals through the coil and the ability to push it into the hole rather than relying on gravity.

Applications
A capillary tube is found in wide variety of refrigerators， water coolers， air conditioners and deep freezers. This component connects the condenser to the evaporator， and its length determines the amount of refrigerant at a specific pressure. Sometimes， issues can pop up that prevent cooling from happening. the capillary tube can be blocked or restricted by solid residues affecting the performance of the refrigerator.
High precision capillary tube is used in many Instrumentation systems which include the use of:
1. HPLC tubing
2. UPLC tubing
3. Coriolis tubing
4. Remote seal pressure transmitter tubing
5. Sheath tubing
6. Hydraulic tubing
7. Medical Equipments/Services
8. Industrial Components
