West-East Gas Transmission Project of Jin City Coal Group is mainly located at an altitude above 800 meters. The main cross section include medium mountain, low mountain and the hilly terrace area, earth-rock mountain region, valley-basin region.etc
Since this year early, the pressure difference between first and last station has reached Max 0.6Mpa, which has already affected the normal gas transmission. Since our Pipeline Commissioning Company (Branch) received this work, an effective working plan was made after site simulation and several times pipeline characteristic analysis using our cleaning technology. Under the cooperative effort of all personnel of project department, the ball pass cleaning was successfully completed with pressure difference between first and last station reduced to 0.03Mpa. Our satisfactory performance has been unanimous accepted and highly spoken by the owner (Jin City Coal Group)
Under the leadership of general manager assistant Mr Xueyun Liu and project manager Mr Suozhu Zhang, the project was started on time. With the spirits of hardworking and braveness and challenge, we thoroughly solved the concerns and worries of the owner and successfully accomplished the work.
Meantime, we are indebted to Guanhui Fu, Fuzhi Liu, Ynafu Zhang,Qingwen Tang, Hanghang Yang, Yonghong Wang.etc for their hardworking and cooperation.
I hope all the employees involved in the project to redouble their efforts, to be modest and prudent, to construct scientifically, and make new contribution to the safe operation of pipelines.  |
