A special oil pipe inner wall drying mechanism with adjustable heating area

Abstract

The invention relates to a heating-area-adjustable special petroleum pipe inner wall drying mechanism which comprises a drying support block. The upper end face of the drying support block is symmetrically provided with two fourth hydraulic cylinders, the top ends of the two fourth hydraulic cylinders are provided with two third flanges through threads respectively, the upper ends of the two third flanges are installed on a main installing block through screws, four main thermal insulation columns are symmetrically welded to the main installing block, and a main drying sheet is installed on the four main thermal insulation columns; the main thermal insulation columns have the good thermal insulation effect, the two fourth hydraulic cylinders can drive the main installing block to do telescopic motion, the main installing block drives the main drying sheet to synchronously work through the main thermal insulation columns, therefore, the distance between the main drying sheet and the pipeline inner wall is adjusted, then the optimal drying distance between the main drying sheet and the pipeline inner wall is achieved, and the drying effect is good. The heating-area-adjustable special petroleum pipe inner wall drying mechanism can achieve a partial rapid drying function of the petroleum pipeline inner wall, is high in working efficiency and has the advantages of being capable of achieving rapid drying within the partial range, good in power saving property, good in drying effect and the like.

Description

technical field [0001] The invention relates to the technical field of petroleum pipeline machinery, in particular to a special oil pipeline inner wall drying mechanism with adjustable heating area. 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 . ...
