QUENCH PIPE SYSTEMS

Cryogenic Systems engineered for the unexpected and designed for peace of mind

Helium: A Brief Overview

Helium is a naturally occurring, non-renewable gas that is primarily extracted during natural gas production. Its unique properties—extremely low boiling point and inert nature—make it the ideal coolant for superconducting MRI magnets. By keeping the magnet coils at cryogenic temperatures near absolute zero, helium enables stable, powerful magnetic fields necessary for high-quality imaging.

Fun Facts: Helium is the second most abundant element in the universe but is relatively rare on Earth. It’s lighter than air, non-flammable, and the only element that remains liquid at extremely low temperatures without solidifying under normal pressure.

Quench Venting

Quench piping is a critical safety feature in every MRI installation. Tekemi designs and installs cryogenic venting systems that direct helium safely out of the building during a rare but possible “quench” event, when helium rapidly transitions from liquid to gas inside the MRI magnet. Our engineered systems eliminate the risk of helium flooding the MRI suite, protecting patients, staff, and sensitive equipment from the hazards of super-cooled gas exposure. Each system is carefully designed per site conditions to ensure code compliance and long-term reliability.

Precision Engineering & Materials

Tekemi quench piping is fabricated from high-grade stainless steel for strength, corrosion resistance, and long-term durability. All sections are welded or equipped with flanged connections to maintain system integrity under extreme cryogenic conditions. To further enhance performance, the piping is insulated with specialized materials that minimize ice buildup, prevent condensation, and protect surrounding structures. This combination of precision engineering and robust construction ensures dependable operation for the life of the MRI suite.
