Flexible transfer lines
High flexibility & lightweight • Minimum heat ingress • Low stored elastic energy
Flexible transfer lines for liquid hydrogen maintain stable operating temperatures due to low heat ingress and enable easy installation with minimum stored elastic energy. Their high flexibility and lightweight design simplify handling, routing, and integration into your cryogenic system.

Quality and safety testing
Our flexible transfer lines are CE-marked and manufactured in full compliance with the EN-13480 standard for metallic industrial piping, delivering vacuum-jacketed, low-heat-leak transfer of cryogenic fluids. Each unit is certified to PED 2014/68/EU and undergoes mandatory EC Unit Verification by an independent Notified Body, ensuring adherence to the EU’s safety regulations for hazardous fluids and high-pressure systems. To ensure operational integrity and safety, every flexible transfer line undergoes:
-
Functional product testing: Validation of system operability.
-
PED compliance tests: Verification of conformity with PED 2014/68/EU requirements.
-
Internal compliance tests: Integrity validation through helium leak detection and other internal assessments.
