Standard ballooning sets are configured of individual elements of the RVB 2010-F system so that they could make it possible for system and complete execution of works at preserving the maximum possible safety level. In principle, they are designed as at least two-chamber units at every side of the closed section (two loading chambers with closing balloons are used at every side of the closed section). For the list of sets including their working range see the next page. For schematic representations of pipeline closing, method of the loading of the closing bodies, layout of ballooning adapting pieces and pictures of individual set elements see the sheets 2.1-1.2 and 2.1.-2. The sets are normally supplied with basic accessories as specified in the set content description on the sheet 2.1-3.1.
