Global joint security specialist Hydratight uses cryogenic freezing as a non-invasive alternative to mechanical plugging, minimising downtime and production losses during maintenance.
Hydratight employs its cryogenic technology for pipelines up to 48” in diameter.
Operating throughout Australia, the Asia-Pacific and 30 countries worldwide, Hydratight’s highly skilled engineers will freeze the process or production media at full operating pressure to form a plug, which allows modifications or repairs downstream without the need to drain the pipeline.
Apart from allowing continued production during pipe work modification or repair, the freezing technique helps maintain the integrity of pipe work with no need to re-test the plug location. Additionally, drainage of media is avoided and production performance maintained.
The cryogenic service complements Hydratight’s mechanical line plugging, which is ideal for temporary or permanent isolation of pipe work, allowing repair or modification without the need for plant shutdown or loss of production or process media. High skilled technicians use purpose-designed equipment for fast and safe mechanical line plugging for emergency and scheduled stopping of a liquid or gas flow in a pipeline at full operating pressure.
Benefits of Hydratight’s cryogenic technology also include the isolation, repair or modification of pipework without production loss as well as the ability to plug and bypass without interruption to process flow.
