Described herein are coiled tubes with improved and varying properties along the length that are produced by using a continuous and dynamic heat treatment process (CDHT). Coiled tubes can be uncoiled from a spool, subjected to a CDHT process, and coiled onto a spool. A CDHT process can produce a “composite” tube such that properties of the tube along the length of the tube are selectively varied. For example, the properties of the tube can be selectively tailored along the length of the tube for particular application for which the tube will be used.

A coil tubing spool handling device includes a base structure and a vertical support structure. The base structure includes an upper surface, a lower surface, and a rocker portion with a curved surface to allow the base structure to rotate along the curved surface. The vertical support structure is connected to the base structure proximate the rocker portion, and extends substantially perpendicular to the upper surface. The vertical support structure and the upper surface can receive a coil tubing spool. A center of rotation of the rocker portion is located in a forward location relative to a center of gravity of the device when the vertical support structure and upper surface receive the coil tubing spool. The relative positions of the center of gravity and the center of rotation bias the handling device to rotate from a vertical position to a horizontal position.

The disclosed manufacture method for a length of tubing can produce a length of fatigue resistant tubing that has relatively high fatigue resistance and relatively low strip-to-strip welding length. The Fatigue resistance is calculated from experimental settings with controlled parameters and/or simulations reproducing similar material properties and loading conditions. A high fatigue resistance means certain product characteristics (e.g., low plasticization, low hydrostatic stress levels and free of imperfections welds) can be retained with an adequate bias weld design at low values after a specific test number of cyclic loading. The relatively low strip-to-strip welding length is an advantage for reducing probabilities of having cracks initiated and/or propagated at weld locations, where imperfections and localized differences of mechanical properties commonly cause failure. Low strip-to-strip welding length can also reduce the costs for welding.
