Petroleum pipe inner wall cleaning and drying treater

Abstract

The invention relates to a petroleum pipe inner wall cleaning and drying treater. The petroleum pipe inner wall cleaning and drying treater comprises an inner wall automatic walking device; the inner wall automatic walking device stably walks on an inner wall of a pipe from four directions, has four walking support forces uniformly distributed, is excellent in uniform support performance, and is excellent in stable walking performance; an inner wall rotary cleaning device is mounted at the middle part of the inner wall automatic walking device, can realize high-pressure cleaning function of the inner wall of the pipe, can perform local high-pressure cleaning according to the pipe inner wall demands, is wide in application range, is precise and adjustable in cleaning angle, is fast in cleaning speed, and is high in cleaning efficiency; and an inner wall drying device is mounted on the left side of the inner wall automatic walking device, can realize a quick drying function of the inner wall of the pipe, and can perform local quick drying according to actual conditions of the inner wall of the pipe. The petroleum pipe inner wall cleaning and drying treater can realize continuous and stable cleaning and drying functions of the inner wall of a petroleum pipe, has no need to replace equipment for operation during the process, is fast in treatment speed of the inner wall of the pipe, and is high in treatment efficiency of the inner wall of the pipe.

Description

technical field [0001] The invention relates to the technical field of petroleum pipeline machinery, in particular to a cleaning and drying treatment machine for the inner wall of petroleum pipelines. Background technique [0002] With the rapid development of the petroleum industry, more and more oil pipelines and water injection pipelines are used in oil fields. Oil and water usually contain corrosive substances, which often lead to pipeline corrosion damage, especially the life of oil pipelines with high water content and sewage reinjection pipelines is greatly shortened, and the replacement of new pipelines faces huge costs. Corroded old pipelines need anti-corrosion treatment. The main way of oil pipeline anti-corrosion is to spray anti-corrosion coating on the inner wall of the pipeline. Before the existing automation equipment is sprayed with anti-corrosion coating, it is usually necessary to carry out the following processes on the inner wall of the oil pipeline: 1 ...

AI Technical Summary

Problems solved by technology

[0003] In order to solve the above problems, the present invention provides a cleaning and drying processing machine for the inner wall of oil pipelines, which can solve the problems of complicated operation, slow processing speed of the inner wall of the pipeline, low processing efficiency of the inner wall of the pipeline, and uniform support of the inner wall of the pipeline. Poor performance, poor self-steady walking performance of equipment, slow equipment cleaning speed, low equipment cleaning efficiency, non-adjustable equipment cleaning angle, inability to perform local cleaning, small application range, inability to perform local drying, large power waste, and low drying effect It can realize the continuous and stable cleaning and drying function of the inner wall of the oil pipeline without changing the equipment operation in the middle. Good performance, good equipment self-steady walking performance, fast equipment cleaning speed, high equipment cleaning efficiency, precise and adjustable equipment cleaning angle, local high-pressure cleaning, wide application range, local rapid drying, good power saving performance It provides a new way of integrated treatment of the inner wall of oil pipelines
