Description
Technical Field
The utility model belongs to the technical field of natural gas pipeline supports, and particularly relates to an adjustable steel structure support for a natural gas metal pipeline.
Background
In recent years, with the overall planning and great support of the country to the clean energy industry, the natural gas industry is continuously developing and innovated nationwide. Particularly in the area where the development of the natural gas in the south is relatively delayed, the development of the natural gas in recent years can be called as a new and advanced day by day and a sudden and violent advance. However, many technologies still use the conventional practice in the northern area, and cannot adapt to local conditions, so that some phenomena of 'water and soil are not suitable' also occur in the actual operation process.
Because most geological conditions in coastal areas in south-east are poor, mucky soil layers are common, and the LNG gasification station, the CNG gas station, the pressure regulating station, the valve chamber and other stations often have site settlement caused by various reasons in the operation process, so that the pipeline and the pipeline support deviate or even separate, and the pipeline is deformed or even cracked and the like to endanger the pipeline. Many natural gas operating enterprises need to take various measures frequently to ensure the operation safety of stations, such as: regular settlement monitoring, weld seam detection, safety assessment, even occasional post-gas-cut technical reconstruction, and the like. Such events occur frequently and are highly dangerous, and present a number of safety risk factors for natural gas owners and downstream gas consumers. Although there are various problems causing safe operation of the pipeline, the pipeline bracket plays a considerable role as an essential component in the pipeline installation process.
At present, the pipeline support mainly adopted in the conventional engineering can be divided into a movable support, a fixed support, a guide support and the like according to functions, and can be divided into a concrete support, a steel structure support, a high-strength composite material support and the like according to materials.
(1) A movable support: the function of the device is to evenly distribute and bear all loads of pipelines, heating media, heat insulation materials, pipe fittings or valves on the pipelines and the like. The movable support, in addition to carrying the above basic loads, may also allow the pipeline to slide freely on the natural gas pipeline support.
(2) Fixing a support: the pipeline is fixed on the bracket at a proper position and is used for bearing the horizontal thrust generated by the pipeline due to thermal expansion.
(3) A guide bracket: the function of the device is to ensure that the pipelines slide along the same axis so as to avoid horizontal transverse displacement of the pipelines.
In conclusion, the function of the pipe bracket in the operation of the pipe is seen in a spot. How to ensure that the pipeline bracket can always play a corresponding role in the operation process is urgent.
