1. According to the pipeline and diameter selection of the
corresponding specifications of the GAS BAG (not to replace)
2. Before use should check the production of GAS BAG and other
defects, with a pressure reducing valve in the gas cylinders
through the GAS BAG tail pipe phase within the filling nitrogen,
to be filled to the pipe diameter size, tied tightly tied tail
pipe. Stored for more than 2 hours, check no leakage, the
discharge of all gas, spare.
3.
According to the construction situation, at a certain distance
from the pipeline construction (6 meters above) on the pipeline
to play a hole (can be put into the GAS BAG), remove the burr on
the edge of the hole, check the tube without foreign matter or
sharp angle, the GAS BAG rolled into a tube, from the hole into
the tube, the isolation side (construction direction), tail pipe
to stay outside, through the tail pipe to the ball filled with
nitrogen (inflation pressure of not more than 0.04Mpa) gradually
GAS BAG ball paste Tighten the inner wall of the pipe, you can
bundle the tail pipe (no leakage). Check whether the gas is
isolated, normal, you can construction.
4. After the completion of the construction, the gas inside the
GAS BAG exhausted, removed from the hole to recover, plug the
hole.

1.根據管道和管徑選用相應規格的油氣管道封堵氣囊（切勿替代）
2.使用前應檢查油氣管道封堵氣囊的生產等缺陷，用減壓反將氧氣瓶中的氣體通過油氣管道封堵氣囊尾管相求內充氮氣，待充到管道管徑尺寸後捆緊,紮牢尾管。存放2小時以上，檢查無泄漏後，排盡氣體備用。
3.根據施工情況，在離管道施工處一定距離（6米以上）的管道上開一孔（能放進油氣管道封堵氣囊為好），去掉孔邊上的毛刺，檢查管內無異物或尖角後，將油氣管道封堵氣囊卷成筒狀從孔中放入管內隔離端（施工方向），使尾管留在外邊，通過尾管向球內衝入氮氣（充氣壓力不大於0.04Mpa）逐步將油氣管道封堵氣囊使球貼緊管壁，即可將尾管捆紮（不得有漏氣）。檢查餘氣是否被隔離，正常後方可施工。
4.施工完成後，將油氣管道封堵氣囊內氣體排盡，從孔中將其取出回收，堵上開孔。
