Material and series selection
- Use only materials qualified for the minimum design temperature.
- Specify project-approved metal hardware and insulation interfaces.
- Define support load under operating, cooldown and upset conditions.

Cryogenic supports require project engineering for low-temperature toughness, contraction, insulation and heat-leak control. Standard polymer clamps are not suitable.
Installation checks
- Allow contraction and guide movement in the intended direction.
- Protect vapour barriers and avoid thermal bridges.
- Review support design with the piping and insulation engineers.
Common mistakes to avoid
- Using standard polymer inserts at cryogenic temperature.
- Locking a line that must contract.
- Penetrating or crushing the insulation system.
Where this service appears
Support design must protect insulation and accommodate large thermal contraction.
Material traceability and project-approved low-temperature hardware are essential.
Support loads and movement at equipment interfaces require coordinated engineering.

Frequently asked questions
Why are ordinary polymer clamps unsuitable?
They can embrittle and lose load capacity far above typical cryogenic minimum temperatures.
Can a clamp pass through cryogenic insulation?
Only as part of an engineered support detail that controls load, vapour sealing and heat leak.
