METALIC EXPANSION JOINTS

Applications:
Metallic expansion joints find applications in various
industries where there is a need to accommodate thermal
expansion, vibration isolation, and movement in piping
systems. Some common
applications include: HVAC Systems: Utilized in heating,
ventilation, and air conditioning (HVAC) systems to absorb
thermal expansion and contraction in ductwork, air
handling units, and chilled water piping.in addition to power
generation, oil and gas, and water
treatment
Material Specifications:
Detailing the specific materials used in the
construction of the expansion joint, including:
•Outer and inner bellows material (e.g., stainless steel,
carbon steel, etc.).
•Additional components such as flanges, liners, and tie
rods.
Size and Dimensions:
Providing the nominal diameter and length of the
expansion joint, along with any variations in size
options available.
Pressure and Temperature Ratings:
Specifying the maximum allowable pressure and
temperature ranges for the expansion joint to ensure safe
operation within the intended conditions.
Movement Capability:
Describing the expansion joint's ability to
accommodate axial, lateral, angular, and/or torsional
movements, often expressed in inches or millimeters.
Corrosion Allowance:
Indicating any additional thickness added to the bellows or
other components to account for potential corrosion over
the expected service life.
Service Life and Maintenance:
Offering information on the expected service life of the
expansion joint under normal operating conditions and any
recommended maintenance practices to extend its lifespan.

Bellows are a kind of flexible pipe. In order to accommodate
pipe expansion and contraction brought on by temperature
variations, the expansion joint's corrugation is made to be
flexible. The
displacement and the expansionary and contracting force that
the bellows must absorb determine how many corrugations
the bellows have. Bellows must be powerful enough to
Pipeline design and
operating pressures, installation pressures, and their flexibility
in absorbing thermal movement are all required. The flow's
thrust
forces the pipes need to be supported by materials other than
bellow
Bellows from TAV Industries are constructed from highly
ductile
cylindrical tubes. The cylindrical body is shaped onto parallel
corrugation, allowing for all fundamental motions without
experiencing the wear and tear that comes with using traditional mechanical
devices. Bellows are engineered and produced
in compliance with the most recent additions to the
EJMA,

ASME, GIS, BS, DIN, and IS
standards, under the
direction of a highly skilled
group of technocrats and engineers.
Our bellows are constructed from tested S.S. 316 / 321 / 304
stainless steel material to achieve high flexibility and a life
expectancy that is above average. When exposed to internal
pressure, these bellows maintain their elasticity. Bellows from
TAV Industries have shown exceptional performance in a range of applications.
NOTE:
•Maximum pressure rating is based on 40 C operating
temperature.
•Due to a policy of continual improvement, the specification is
subject to change without prior notice.
•Measurements are subject to a 5% tolerance
