    Nowa metoda dwustronnego balonowania zespołów zaporowo-upustowych (ZZU)
    (2008) Galas, Marek; Wilk, Stanisław
    Among the presently used hermetic ballooning methods applied for cutting off the gas flow in a pipeline for making repairs, the ballooning method is most popular. It lies in introducing balloons through special stub pipes welded to the gas pipeline, which is an undesired ingerention in the structure of the existing gas pipeline. New ballooning technology lies in introducing balloons to the gas pipeline through the existing exhalation columns. With this method the welding operation can be avoided as it is an undesired ingerention in the structure of the existing gas pipeline.
