LTi Metaltech is the lead supplier of the cryogenic pressure vessels used in Siemens’ Magnetic Resonance Imaging (MRI) scanners.


Formerly part of Siemens MR Magnet Technology, LTi is the lead manufacturer of the cryogenic pressure vessels which have been used in Siemen’s Magnetic Resonance Imaging (MRI) scanners for over a decade, exported for installation in hospitals and medical facilities around the globe.


LTi manufactures over 2,000 pressure and vacuum vessels per year, used to encapsulate liquid Helium that cools superconducting electromagnets to 4 Kelvin (-269 degrees Celsius).


With a history of being part of a leading blue chip organisation, LTi is a Tier 1 supplier that has invested in the latest equipment, technology and working practices to manufacture products to strict industry standards, with lifetime records and traceability for all materials and components. To ensure the integrity of these components, the company performs very high levels of quality control and testing throughout the production and fabrication process, from visual welding inspection through to X-Ray and high vacuum testing.


Employing a ‘design to cost’ methodology, our technical experts were able to deliver bespoke solutions at lower costs. As a result of the partnership, weight reduction of the cryogenic vessels was reduced by 20%, and an overall cost and size reduction of 10%.


LTi Metaltech are proud to have developed its partnership with Siemens and place into full production its vessels, leading to investment for R&D initiatives and latest equipment and facilities.


Typical component characteristics include:

  • Stainless steel manufacture
  • 500kg to 1,000kg weight
  • Tolerance +1/-1mm


As members of the British Cryogenics Cluster and The Welding Institute (TWI), we are committed to working in partnership with key sector service providers in delivering practical solutions to help meet the technological and manufacturing challenges of the next 10-20 years. We are recognised for being able to optimise environments to achieve volume manufacturing of highly specialised products.
