| Abstract: | To satisfy the construction requirement on joint coating in China-Russia Eastern Gas Pipeline Project(the first phase) in winter, a series of comprehensive analysis were carried out, including analysis on low-temperature mechanical performance of materials, structure optimization design, low temperature test, optimal selection of cryogenic electronic component, mechanical temperature control, heating element at alternating high and low temperature, and comparative analysis on domestic and foreign low-temperature patching materials. Then, the mechanized joint coating equipment suitable for the low-temperature environment of-40 ℃ was developed, and its matching process and construction plan were prepared. Engineering application shows that the equipment and process of low-temperature mechanized joint coating can effectively guarantee the joint coating quality and construction efficiency of the test section and the first phase section in China-Russia Eastern Gas Pipeline Project. And its average daily coating is 30 with one pass rate of 100%. In this way,a great deal of construction experience of joint coating for large-diameter pipelines in low-temperature environment is accumulated, which can provide technical support for the joint coating of China-Russia Eastern Gas Pipeline Project(the second phase) and similar pipeline. |
