News Release

The long-distance directional drilling of Guoxin Huai’an Natural gas pipeline achieved a great success


        In the early morning of 1:45 on Match 16, a good news came from Guoxin Huai’an Natural gas pipeline project site that the 18-kilometer-long pipeline successfully cut through Huaihe River Sea-entering Channel and Subei General Irrigation Canal at one time. It only took 15 hours to finish the whole process ,which was 11 hours less than the original plan.

        It is reported that the long-distance natural gas pipeline was a high-pressure pipeline with design pressure of 63km and diameter of φ519 . The pipeline of section II constructed by NO.16 Branch Company was 12km. And 1.8km of that pipeline which cut though the Huaihe River Sea-entering Channel and Subei General Irrigation Canal was constructed in the way of directional drilling and dragging pipe, which is the key and difficult point of the project. The data shows that such long directional drilling construction is the fifth length in Jiangsu province, even not common across the country. Under all the staff’s efforts, Guoxing Huaian Natural Gas Pipeline Project finally succeeded after conquering so many unfavourable factors such as maximum depth of -13m and uneven soil quality of  calcareous sandstone mixed clay.
