Expansion joints Teguflex
®
Functions and advantages
► Compensate for thermal elongation.
► Isolate vibrations.
► Absorb water hammers.
► Compensate misalignments.
► Ensure sealing of the pipe.
Stainless steel vacuum ring
The vacuum ring is recommended when the
expansion joint is used in negative pressure
(pumps, etc).
Available in stainless steel 316 Ti.
PTFE lining
PTFE lining is recommended for acids and
strong and/or condensed bases.
Movements allowed by the expansion joints
are then reduced by 50 %.
The use in negative pressure is forbidden.
Maximal pressure: 6 bar.
