Molten Metal Manipulation (M3)

Bismuth Pligs

Secure, Instant, Yet Easily Reversible, Alloy Coatings and Seals

Maximising our knowledge of bismuth alloy seals for oil and gas reservoir plugging & abandonment, we are developing Molten Metal Manipulation (M3) – a range of new alloys and application techniques to provide instant, yet easily reversible metal seals for the nuclear industry, defence and various industrial sectors.

Using specially developed alloy classes that can be applied in air or under water, we offer secure metal seals and collars that can be used for sealing and encapsulation, and to repair leaks and cracks in storage tanks and civil structures.

Rawwater M3 technology is based on our ability to manipulate low melting point bismuth alloys prior to solidification, to achieve repairs or provide metallic coatings.

Rawwater M3 alloys deliver extraordinary performance in the most challenging of environments. Their various attributes include:

  • Applied in air or under water – using different techniques for different applications 
  • Individual alloy classes for different operating temperatures
  • Molten alloy ‘spray’, ‘bullet’ and ‘casting collar’ application techniques
  • Rapid application and instant curing
  • Easy removal and reapplication
  • For both low pressure and higher pressure leaks
  • Very little surface preparation required
  • Can be applied to fuel tanks and systems containing combustible media - without the need to degas 
  • Can be applied to metals, concrete, ceramics, elastomers, polymers, composites and combinations

Demonstration of leak repair using low-temperature metallic deposition technology:
