Abstract

The invention discloses a curing oven and a tubular column conveying and rotating device and method used in the curing oven. The curing oven comprises: an outer shell, wherein a heating rod is arranged in the outer shell; the tubular column conveying and rotating device, wherein the tubular column conveying and rotating device is arranged in the outer shell. The tubular column conveying and rotating device comprises a tube conveying device, an auxiliary supporting and lifting device and a clamping and rotating device, wherein the auxiliary supporting and lifting device is located on the inner side of the tube conveying device, and the tube conveying device is located on the inner side of the clamping and rotating device. According to the curing oven, the functions of automatic conveying, clamping, rotating and curing of an oil tube can be achieved, the oil tube obtained after solvent-free liquid spraying is kept in the rotating state in the curing process, it is guaranteed that a sprayed coating is free of sagging and cured evenly, and the spraying quality of the internally-coated oil tube is guaranteed.

Description

technical field [0001] The invention relates to the technical field of curing of internal oil-coated pipes, in particular to a curing furnace and a pipe string conveying rotating device and method used inside the curing furnace. Background technique [0002] During the oilfield production process, the tubing is prone to corrosion, wear, fatigue and breakage due to the immersion of the high-salinity output fluid, the contact with the sucker rod during pumping, and the alternating load of the pumping inertia. At present, the internally coated tubing used in the oil field mainly uses epoxy powder as a coating to spray on the inner wall of the tubing, and forms an internal coating after curing. However, due to the low adhesion of the coating, it is easy to fall off; the thickness of the coating is thin, and the coating is easily damaged due to the wear and tear of the rod tube, etc., which have affected its large-scale application. In order to overcome the above problems, solve...
