Stoppering a High-Pressure Gas Pipeline DN 100 in Prague: A Technical Challenge Mastered by Our Expert Team
Recently, we undertook a particularly interesting and demanding project in Prague – stoppering a high-pressure (VTL) gas pipeline DN 100 on a vertical section of the pipeline, installing the device perpendicular to the pipe, i.e., at a right angle. This combination is one of the most challenging our installers and designers can face.
What does “installation perpendicular to a vertical pipeline” mean?
The stoppering device we use must be positioned horizontally during installation and welding, even though the pipeline to which it is connected is vertical. This situation significantly complicates the work of our installation team – handling heavy and precise equipment in such a position requires not only physical strength but also a great deal of experience, coordination, and precision.
Appreciating our team
Without the work of our installers, who never hesitate to take on these physically and technically demanding tasks, such a project would not be possible. Equally crucial is the work of our designers, who continually improve the technology to handle even the most unusual situations. The entire FASTRA team forms the foundation that allows us to respond to a wide range of challenges in the field.
How the implementation proceeded
Although the installation handling was demanding, everything went smoothly. Our STOPL-S4-F1 stoppering set proved its reliability even in complex spatial conditions and ensured perfect sealing of the pipeline without any natural gas leakage. For maximum safety, we additionally installed a securing balloon as an extra protective element.
The STOPL-S4-F1 technology is designed for high-pressure product pipelines with pressures up to 40 bar and enables safe operation on pipelines with unconventional directional layouts – horizontal, inclined, and vertical.
Challenges and solutions – what drives us forward
Projects like this constantly push us forward and confirm that there is no problem that cannot be solved with determination, the right team, and quality technology. We believe that the strength of our company lies precisely in people – in their experience, skills, and willingness to tackle even the toughest tasks.
