The small compensators are axial expansion joints, which are mainly
applied in buildings and industrial piping systems. Their main element
is the multiply stainless steel or bronze bellow. The compensator
is equipped with an external protective pipe guide, preventing possible
damage during installation, providing easy installation and attractive
The inner sleeve, which is used, grants for the smooth flow of the
medium and protects the bellow from deformations caused by high temperature
The small compensators are delivered pretensioned and ready for installation.
This is achieved with the pretensioned ring with which the compensators
are equipped. In low temperatures the overall length of the small
compensator must not exceed the original one (pretensioned length).
In high temperatures the length of the small compensator must not
be less than the values mentioned at the tables (provided by Metalloviotechniki).
