Method and system of manufacturing coiled tubing

A system comprising:

• a feeder configured to feed a continuous length of a tube at a predetermined feed rate, wherein the tube has one or more predetermined geometry values, wherein the one or more predetermined geometry values comprises a wall thickness;
• a first treatment station comprising a first entrance, a first exit, and at least a first heat treatment zone therebetween, the first heat treatment zone comprising at least one first zone heating element;
• a second treatment station comprising a second entrance, a second exit, and a second heat treatment zone therebetween, the second heat treatment zone comprising a second zone heating element;
• and
• a controller configured to (i) power the first zone heating element at an initial heat treatment power level based on the one or more predetermined geometry values of the tube, (ii) adjust power to the first zone heat element based on the wall thickness, and (iii) power the second zone heating element at a second treatment station power level based on the one or more predetermined geometry values of the tube.
