Visual detection system of bimetal composite pipe

Abstract

The present invention provides a visual detection system of a bimetal composite pipe. The detection system comprises a chamber body, a car frame, a driving unit, a battery group, a support guide wheelset, a signal receiving and sending apparatus, a camera component, a deformation sensing component, a positioning unit and a remote controller. The deformation sensing component comprises a deformation detector and a deformation signal storage. The deformation detector can detect deformation of an inner pipe wall, the deformation signal storage receives and storages a deformation signal, and thesignal receiving and sending apparatus can receive information stored by the image storage, the deformation signal storage and the positioning unit, and send the information to a display of the remotecontroller. According to the visual detection system, a picture of an inner wall of a bimetal composite pipe screened pipe can be displayed in real time, a detection period can be obviously shortened, and a device downtime time is reduced; a position of deformation of the bimetal composite pipe screened pipe can be accurately positioned, unnecessary excavation detection is avoided, detection efficiency is obviously improved, detection costs are reduced; inner wall detection can be performed for pipes of different pipe diameters, and adaptation is strong.

Description

technical field [0001] The invention belongs to the field of underground pipeline detection, and specifically relates to a visual detection device capable of detecting bimetal composite pipes used in oil and gas field exploitation or oil and gas transportation. Background technique [0002] At present, bimetallic composite pipelines have been widely used in oil and gas field exploitation and oil and gas transportation, although bimetallic composite pipelines can better solve the problem of high H content 2 S, Cl - and CO 2 Oil and gas field pipelines have corrosion problems, but there are still deficiencies in the use process. The liner of the bimetallic composite pipeline adopts the API 5LC standard, which only lists 5 kinds of materials, and does not include H 2 S / CO 2 The material used in the environment. During the use of bimetallic composite pipelines in some blocks of the oilfield, it was found that the liner of bimetallic composite pipes was deformed, collapsed, a...
