The STOPL-S4-F1 is used to temporarily interrupt the flow of the media in steel pipelines with internal overpressure (or without overpressure) without any leakage of the medium (also referred to as pipeline shut-off). Its main advantage is that it enables work on pipelines with a pressure range of 0-40 bar. The device principle differs from the previous types. The stopple rod is incorporated in a closed chamber and the rod itself is hidden.
The components of the new equipment are high-pressure rated and tested according to CSN and TPG rules.
Advantages:
- Overpressure in pipeline to be sealed off within the range of 0-40 bar.
- Quick and easy assembly.
- Substantially reduces the preparation time for individual technological operations.
- High variability.
- Simple bypass solution.
- High level of safety.
Technical parameters:
Material and diameter of pipeline to be sealed off: DN80-DN350 steel pipe
Media: natural gas, hydrogen, non-aggressive gases, other media after consultation with the manufacturer.
Overpressure in pipeline to be sealed off: 0-40 bar
Operating temperature: -10/+50°C (other after consultation with the manufacturer)
Certification
Following successful trials and tests, we have obtained a professional and binding opinion of the TECHNICAL INSPECTORATE OF THE CZECH REPUBLIC on the STOPL-S4-F1 for use at an operating pressure of 0-40 bar.
