Because the plugs are neutrally buoyant they can also be used in sub-sea environments.

and weld purging of pipes in harsh environments. The plugs can also be used to seal and protect tanks, vessels and containers during cleaning and transportation, particularly when they are pressurised with inert gas. All plugs conform to British Standards BS8005 and BS EN752-4 for low- pressure testing and sealing of pipes. Other expandable plugs and stoppers in the Pipestoppers division employ nylon or steel as the main body material. Lightweight inflatable stoppers are also available. Aluminium plugs are referenced in the HFT white paper ‘Welding of Zirconium and its Alloys’, available on the Huntingdon Fusion Techniques website. Huntingdon Fusion Techniques – UK
