Embodiment Construction

[0016] Below in conjunction with accompanying drawing, invention will be further described:

[0017] The process of spraying homogeneous drying in double pipes of the present invention comprises the following steps:

[0018] ①Pipe loading process: first move the pipeline to be sprayed from the loading rack to the predetermined position through the transmission line, and then lift it to the transition frame;

[0019] ②Double-pipe lifting process: When there are two pipelines on the transition frame, they are lifted to the spraying frame at the same time;

[0020] ③Double-gun spraying process: The spraying vehicle is moved to spray the double-pipes at the same time with two guns to carry out anti-corrosion spraying on the inner holes of the double-pipelines. After the spraying is completed, the spraying vehicle returns;

[0021] ④ Homogenization process: lift the sprayed pipeline to the homogeneous frame, and the homogeneous frame drives the sprayed pipeline to rotate, so that ...

Abstract

The invention relate to spraying and anticorrosive treatments on inner bores of long and thin pipelines for oil fields, in particular relates to a process and production line of spraying, homogenizing and drying in a double-tube and mainly aims to improve the production efficiency and ensure the spraying quality. The process comprises the following steps of: 1, carrying out a tube-feeding process; 2, carrying out a double-tube lifting process; 3, carrying out a double-gun spraying process; 4, carrying out a homogenizing process; 5, carrying out a tube placing process; and 6, carrying out a drying process. The whole processes can be implemented on the production line and controlled by a PLC (programmable logic controller) computer automatic control system. The process is a complete set of production process integrating spraying, homogenizing and drying, the efficiency can be improved by above 50%, and the device is convenient to operate and is safe and reliable.

Description

technical field [0001] The invention relates to an anticorrosion treatment process and equipment for spraying the inner holes of long and thin pipelines used in oil fields, in particular to a double-pipe inner spraying homogeneous drying process and production line. Background technique [0002] At present, in the equipment used for anti-corrosion spraying in oilfield pipelines, the mechanical transmission part can only be used for single-tube transmission and single-tube spraying. The production efficiency of the device is low, and the transmission connection of the pipelines is poor during the transmission process. Collision between pipelines is easy to cause equipment damage or safety accidents, and there are disadvantages such as high failure rate and poor safety. Contents of the invention [0003] In order to improve the production efficiency, reduce the failure rate, and ensure the anticorrosion quality of the pipeline, the invention provides a double-pipe internal s...
