Abstract: Embodiments of the present disclosure are directed to coiled steel tubes and methods of manufacturing coiled steel tubes. In some embodiments, the final microstructures of the coiled steel tubes across all base metal regions, weld joints, and heat affected zones can be homogeneous. Further, the final microstructure of the coiled steel tube can be a mixture of tempered martensite and bainite.

Abstract: 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.

Abstract: A quenching tank system includes a cooling tank having an entrance opening adapted to allow a first portion of a heated continuous tube to enter the cooling tank and to allow a first portion of a cooling fluid in the tank to flow out the entrance opening. The cooling tank includes an exit opening adapted to allow a partially cooled second portion of the continuous tube moving through the tank to exit the cooling tank and to allow a second portion of the cooling fluid in the tank to flow out the exit opening. The system also includes a cooling fluid collection and distribution system adapted to collect cooling fluid flowing out of the cooling tank, return the collected cooling fluid to the cooling tank and distribute the cooling fluid in the cooling tank. A method of cooling a heated continuous tube using a quenching tank system is described.

Abstract: 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.
