Sealing services

We specialize in sealing works on gas pipelines using advanced technologies:

  • TD Williamson (DN50 – DN700, ANSI 600)

  • Secret-EGG (DN25 – DN100, ANSI 600)

  • SIMPLY 50 (up to DN80, MOP 5 bar)

Using the hermetic (sealing) method, we can perform:

  • hot tapping of pipelines,

  • single-sided pipeline isolation (single-sided gas pipeline stopping),

  • double-sided pipeline isolation (double-sided gas pipeline stopping),

  • double-sided isolation with a temporary bypass – gas pipeline stopping with bypass.

The use of the hermetic method enables, among other things:

  • connecting new consumers, pressure-reduction and metering stations, or gas wells to the existing gas network,

  • integrating new high-pressure gas pipelines with the current infrastructure,

  • constructing bypasses for renovated gas facilities, and modernization or construction of new facilities on active pipelines (e.g. shut-off and blow-down assemblies, condensate traps, monoblocks, etc.).
