Calling on more than 20 years’ expertise gained developing bismuth alloy seals for use in some of the world’s most challenging environments, we have created M3 Molten Metal Manipulation: a range of low-melting-point, reversible alloy seals and application techniques for the rapid recovery of leaks and cracks in civil structures, seals, joints, flanges and pipelines, as well as planned preventive maintenance.
M3 can be deployed against flowing leaks, without the need to drain systems or shut down processes. Reapplication is straightforward and recovered alloys can be reused. Repairs can be completed in both challenging and difficult to access environments – all without the need for hot work.
We have a deep understanding of metal alloy placement in a range of scenarios. The challenges we have been tasked with include:
Remote leak sealing
Sealing micron-sized defects
Sealing defects of up to one centimetre
Sealing underwater
Sealing against pressurised gas leaks
Seals withstanding 15bar of re-pressurisation
Sealing various substrates including plastics, composites, various steels, rubber, concrete and GRP
Recovering water, oil and gas leaks
Temporary retrievals
Ingress control
Longevity testing of seals
As an indication of the immense capabilities offered by M3, we are currently working with National Nuclear Laboratory Ltd, Sellafield Ltd and Tokyo Electric Power Company (TEPCO) to develop our in-service alloy seals for various challenges that can occur during decommissioning activities.
We are also collaborating with National Grid to trial M3 as a rapid, safe and highly effective way of sealing harmful sulphur hexafluoride (SF6) greenhouse gas leaks from electrical equipment. M3 technology is based on our ability to manipulate low-melting-point bismuth alloys prior to solidification, to achieve long-lasting seals and repairs. To find out more, please get in touch.
