Petroleum and natural gas pipeline connecting and fixing pipe clamp support

Abstract

The invention belongs to the technical field of pipeline connecting equipment, and particularly relates to a petroleum and natural gas pipeline connecting and fixing pipe clamp support. The petroleumand natural gas pipeline connecting and fixing pipe clamp support comprises sliding blocks slidably installed in annular sliding grooves, and the sliding blocks are connected through connecting rods;the sliding blocks are sequentially provided with second threaded holes and third threaded holes; the second threaded holes penetrate through the sliding blocks, and the depth of the third threaded holes is one half of the height of the sliding blocks; containing grooves, first oil grooves and second oil grooves are formed in the sliding blocks provided with the third threaded holes, and third oilgrooves communicating with the second oil grooves are formed in the connecting rods; fourth oil grooves and fifth oil grooves are formed in the sliding blocks provided with the second threaded holes,and one-way valves are arranged in the first oil grooves and the fourth oil grooves; and supporting mechanisms are installed on the vertical outer end faces of the sliding blocks. According to the petroleum and natural gas pipeline connecting and fixing pipe clamp support, a layer of oil film is generated between the sliding blocks and the annular sliding grooves, corrosion is avoided, and the supporting capability of the pipe clamp support on a pipeline is improved; and in addition, vibration from a pipeline well protecting plate is greatly relieved while the supporting effect is guaranteed.

Description

technical field [0001] The invention belongs to the technical field of pipeline connection equipment, and in particular relates to a bracket for connecting fixed pipe clips to oil and gas pipelines. Background technique [0002] Oil and gas pipelines refer to pipelines that transport oil and natural gas from mining sites or processing plants to urban distribution centers or industrial enterprise users. Oil and gas pipeline transportation has the advantages of low transportation cost and easy remote centralized monitoring. Oil and gas pipeline wells are vertical wells used to arrange vertical oil and gas pipelines in transportation lines. When oil and gas pipelines are installed in pipeline wells, they need to be connected by pipe clamp brackets, and the protection of pipeline well guard plates to pipelines. support. The existing pipe clip brackets have the following problems in actual use: (1) Due to the harsh environment in the pipe well and the poor air circulation, the ...

AI Technical Summary

Problems solved by technology

[0004] The invention provides an oil and gas pipeline connection fixed pipe clip bracket, the purpose of which is to solve the following problems existing in the existing pipe clip bracket: (1) because the environment in the pipeline well is relatively harsh and the air circulation is not smooth, the pipe clip bracket and The contact surface of the pipeline is prone to corrosion for a long time, resulting in damage to the support ability of the pipe clamp bracket to the pipeline; (2) The pipeline well guard plate will transmit the vibration on the ground to the pipeline through the pipe clamp bracket, and the pipeline will be damaged under the action of long-term vibration prone to damage and leakage
