Embodiment Construction

[0035] Polishing methods include: mechanical polishing, chemical polishing, electrolytic polishing, ultrasonic polishing, fluid polishing and magnetic abrasive polishing. Among them, mechanical polishing and chemical polishing are widely used.

[0036] Mechanical polishing, the mechanical polishing is to obtain a smooth surface by cutting and plastically deforming the surface of the material to remove the polished convex part. Generally, oil stone strips, wool wheels, sandpaper, etc. are used, mainly by manual operation, and special Auxiliary tools such as turntables can be used for the surface of parts such as rotary bodies, and ultra-fine grinding and polishing methods can be used for high surface quality requirements.

[0037] Chemical polishing, the chemical polishing is to make the microscopic convex part of the surface of the material dissolve preferentially compared with the concave part in the chemical medium, so as to obtain a smooth surface. The main advantage of th...

Abstract

The invention discloses a high-trafficability pipeline reducing detection and positioning device which comprises a shell and an inner cavity, one end, facing the advancing direction, of the shell is arranged to be a round head, and the other end of the shell is arranged to be a flat head. The outer circumferential side face of the shell makes contact with the inner wall of the pipeline. An inner cavity is formed in the shell, an intelligent analysis control mechanism, a positioning mechanism, a signal transmitter, an inertia measurement mechanism, a power supply system and an information acquisition and storage mechanism are arranged in the inner cavity, and the functions of detecting and positioning the reducing condition of the pipeline along the way are achieved. The device is made of an all-polyurethane foaming material, has high passing performance and low requirements on a pipe inlet environment, and utilizes the jet pipe and the high-pressure combined fan-shaped nozzle to wash dirt on the inner wall of the pipeline, so that the blocking risk is greatly reduced, and the safety of pipeline detection is ensured.

Description

technical field [0001] The present application relates to the technical field of pipeline detection, in particular to a high-throughput pipeline variable diameter detection and positioning device. Background technique [0002] In recent years, with the rapid development of my country's oil and gas industry, the length of long-distance oil and gas pipelines has accumulated to more than 170,000 kilometers, and it is expected to reach 240,000 kilometers in 2025. With the prolongation of pipeline operation time, the aging problem of pipeline is becoming more and more serious, and the safety of pipeline operation has been paid more and more attention by people. According to the analysis of pipeline accident statistics at home and abroad, the early and late stages of pipeline operation are the high incidence of accidents, and pipelines are inevitably affected by many factors such as weather, environment, third-party construction damage, and pipeline aging, resulting in varying deg...
