Abstract: The installation of heat shrinkable tape stator by using the artificial torch during the construction of anticorrosionjoint coating on existing oil and gas pipelines is faced with great influence of human factors, large difference of qualityand low efficiency. To solve these problems, a portable fast installation device for the heat shrinkable tape stator wasdeveloped in this paper. By virtue of this device, the mechanized fast installation of heat shrinkable tape stator can berealized. The test result shows that this portable fast installation device for heat shrinkable tape stators is advantageous withreasonable structure, simple operation, convenience and portability, good installation quality, high efficiency and short timeconsumption, and it can meet requirements on the flow process of mechanized anticorrosion joint coating on oil and gaspipelines. In addition, this device is adaptable to the construction environment of extremely low temperature (－40 ℃), so asto effectively guarantee the construction quality of anticorrosion joint coating on oil and gas pipelines in high and coldareas.
