Fabric Expansion Joints consist of fabric, heat insulation cotton
and metal components. It can not only absorb axial movements of
pipelines by flexibility deformation of fabrics, but also
compensate a little lateral movements or axial and lateral
movements in combination. Besides, it can compensate angular
movements.
As fluoroplastics and organosilicone are parts of materials, the
product has many advantages, such as zero thrust, simplified
support design, corrosion resistance, high-temperature resistance,
vibration decoupling, noise reduction etc., so it usually applies
to warm-air pipes and smoke pipes.
There are two ways of installations, one is the flanged connection,
the other is weld end connection. The tie rod of this type of
expansion joints is only used to support during the transportation
or as an adjustment for the product’s pre-deformation but not to
carry any force.
Nominal Diameter: DN80-DN8000

Material of Connection: Carbon steel GB/T 700 for standard
use(Special material of connection to meet specific customer &
industry requirements)
Other choices: Inner sleeve, carbon steel, AISI304(AISI321 and
AISI316L are also available)
Notes: If you have any other requirement, please contact us.
Product advantage:
(1) Multidimensional direction can be compensated. Various forms,
large compensation and long service life;
(2) Effective compensation or elimination of installation errors;
(3) Low stiffness and small elastic reaction;
(4) High temperature range and good corrosion resistance;
(5) It can effectively isolate vibration and reduce noise.
Scope of application:
Non-metallic compensators are widely used in the entrances and
exits of flue gas desulfurization, dust removal equipment, air
heating, flow-assisted blast and other equipment in iron and steel
plants, smelters, petrochemical plants, thermal power plants,
cement plants.
