Coiled Tubing (CT) has been defined as any continuously-milled tubular product manufactured in lengths that require spooling onto a take-up reel, during the primary milling or manufacturing process. The tube is nominally straightened prior to being inserted into the wellbore and is recoiled for spooling back onto the reel. Tubing diameter normally ranges from 0.75 in. to 4 in., and single reel tubing lengths in excess of 30,000 ft. have been commercially manufactured. Common CT steels have yield strengths ranging from 55,000 PSI to 120,000 PSI. The highest yield strength of CT available now is 130,000PSI.
Except for the carbon steel Coiled Tubing corrosion resistance tubing is also available whose material is 2205 the duplex stainless steel.
Below table contains the most popular tubes applied in the market.
