Oil and natural gas pipeline erection construction method

Abstract

The invention relates to an oil and natural gas pipeline erection construction method, and uses an oil and natural gas pipeline erection construction device. The oil and natural gas pipeline erectionconstruction device comprises a work truck, a first clamping mechanism, a second clamping mechanism and an electric sliding block, the first clamping mechanism is installed at the left end of the upper end surface of the working truck, the second clamping mechanism is arranged on the right side of the first clamping mechanism, and the electric sliding block is installed at the lower end of the second clamping mechanism and installed at the upper end of the working truck through a sliding matching manner. According to the oil and natural gas pipeline erection construction device, the design concept of an adjustable clamping structure is adopted to carry out the erection construction of oil and natural gas pipelines, the oil and natural gas pipeline erection construction device can conduct installation of a single pipeline and docking of two pipelines simultaneously, a plurality of horizontal test control structures are arranged to conduct horizontal calibration in the process of singlepipeline installation and two pipeline docking, and the overall stability of the pipeline and the accuracy of two pipeline docking are improved accordingly.

Description

technical field [0001] The invention relates to the technical field of pipeline laying, in particular to a method for erecting oil and gas pipelines. Background technique [0002] A pipeline is a device connected by pipes, pipe connectors and valves to transport gas, liquid or fluid with solid particles. Usually, after the fluid is pressurized by a blower, compressor, pump and boiler, the high pressure from the pipeline It can also be transported by the pressure or gravity of the fluid itself. The pipeline can be divided into four categories according to the material, pressure, conveying temperature, and conveying medium. The pipeline has a wide range of uses, mainly used in water supply, drainage, and heat supply. , gas supply, long-distance transportation of oil and natural gas, agricultural irrigation, hydraulic engineering and various industrial installations, among which oil and gas pipeline transportation has the advantages of low transportation cost, small land occupa...

Problems solved by technology

[0003] 1. In the process of manual support and fixed installation of the pipeline, the center of gravity of the pipeline is prone to deviate, which makes the connection between the pipeline and the installation position inaccurate. The position of the pipeline placed by manual or mechanical means is prone to position deviation and the pipeline is tilted. state, and thus the overall stability of the pipeline is relatively low;

[0004] 2. The commonly used pipeline erection device only clamps and installs a single pipeline. The working steps in the process of erecting long-distance pipelines are relatively cumbersome and the work efficiency is low. When the two pipelines are docked manually, the phenomenon that the two pipelines are not at the same level may easily occur. This causes a large deviation in the butt joint of the two pipes, and the tightness of the joint between the two pipes is poor
