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) to 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.
Coiling may also be used to treat a condition called arteriovenous malformation, or AVM. An AVM is a group of abnormal blood vessels (arteries and veins) in the brain, spinal cord or elsewhere in the body. The coils used in this procedure are made of soft platinum metal and shaped like a spring.
