DESCRIPTION

Tissue compensators, or tissue expansion joints, are flexible connectors designed to provide stress relief in conduction systems by absorbing movement. 

They are used to solve four main situations:

– The expansion and contraction of the duct due to changes in temperature.
– Component isolation to minimize the effects of vibration and noise.
– The movement of components during process operations.
– Installation or disassembly of large components and assembly tolerances or adjustments.

Advantages of fabric compensators include:

– Large movements in short length.
– Ability to easily absorb simultaneous movements in more than one plane.
– Very low forces are needed to move the compensator.
– Corrosion resistant construction materials.
– Resistance to noise and vibration.
– Ease of installation and maintenance.
– Minimum replacement cost.

Depending on the sector and the working conditions, the type of construction and the compensator materials, we adapt to these conditions to provide the best service at a competitive price. Our associates normally use compensators in installations together with industrial centrifugal and axial fans, but they can also be installed at any point in the installation where it is needed. 

The effectiveness of the compensator depends on the design of the frames to which the flexible element is attached. It is possible to make many variants of frames, depending on the structure to which the compensator is attached. To respond to the different requirements of each application, our associates have developed many different designs and forms of construction.

SINGLE BAND WITH CLAMP

Textile compensator tied to the duct with fastening clamps, suitable for circular ducts with moderate temperature and pressure. It is very easy to handle and assemble, and allows the absorption of light to medium movements and vibrations.

FLANGED COMPENSATOR

Textile compensator in which the flexible element has flanges formed at right angles screwed to drilled plates. They offer the technician designing the duct the simplest method of joining, however the nature of their construction restricts their use at high temperatures. Ideal for compensating axial, angular, lateral and simultaneous movements.

BAND TYPE COMPENSATOR

Textile compensator in which the flexible element is made as a flat band screwed to drilled plates. Provides the most efficient closure from both a manufacturing and bonding point of view. The frames for this type of compensators can be slightly complex, but this is compensated by the ease of repair or replacement of the flexible element. Recommended for applications with high temperature and pressure and in need of noise reduction / absorption. Great ability to absorb moderate and simultaneous movements.

MANUFACTURING

Our associates have a robust manufacturing. Complying with the quality standards set by the company to guarantee a functional, durable and quality product.

SUPERFICIAL TREATMENTS

Our associates have a robust manufacturing. Complying with the quality standards set by the company to guarantee a functional, durable and quality product.

MOUNTING

The compensator assembly is done carefully, checking the clearances indicated on the drawing to guarantee the admissible displacements. They are sent to the customer with some blocking plates to protect it during transport and handling on site. These locking plates must be removed before the installation starts up.

MATERIALS

We manufacture with different materials depending on the operating conditions of the fluid. The parameters that influence the selection of the fabric material are: Pressure and temperature of the fluid that circulates inside the duct. 

To determine the materials of the metal parts we would need the characteristics of the fluid and its composition. The materials we usually work with are: S275JR, AISI-304L, AISI-316L, 16Mo3, HARDOX-400 …

For fluids with abrasive particles we use anti-wear materials to make the compensator durable. We select the most suitable material for the operating conditions, or we manufacture under the indications or regulations of the customer’s installation.

DOCUMENTATION

In the documentation that we send to our clients, we show the general dimensions of the assembly with its connection flanges. We indicate the radial and axial displacements that compensators can have without collision between the metal parts.

INTERNAL DEFLECTORS

Its design is closely associated with the design of the compensator frame. It acts as an inner jacket that protects the textile element from possible abrasion and thermal impact. We design them to not trap dust or condensation and we guarantee that movement is not restricted.

BOLSTERS

Insulating element that provides additional thermal protection to the compensator through the use of insulating materials. They improve the acoustic performance of the compensator, prevent solid particles from entering the compensator cavity, and provide support to the flexible element by minimizing the effects of vibrations.
