elastomeric
expansion joints
An expansion joint of this type is a flexible connector, produced with natural or synthetic elastomer, reinforced with polyester canvas and steel rings.
Its design and material depend on the service needed, as well as the operation condition and the containing liquid. Additionally to the characteristics of design and properties of the material, a variety of accessories can be added to adapt to the presented specific situation.

One arch with integrated flanges
The construction is out of canvas and rubber, reinforced with metal or wire rings. It is designed with one simple arch or with major radio, which increases its capacity of movement and self-cleaning.
Flanges with complete face are integrated in the body of the joint. The rubber flange is thick enough to seal efficiently the partner flange without the use of gaskets.
Multiple arches with integrated flanges
This joint is similar to the one arch joint, but it has an increased capacity in absorption, depending on the number or arcs. To maintain horizontal stability it is recommended to not use more than 4 arches.
Concentric reduction
The reduction joints are used to join pipes with different diameters without the loss of the axial shaft center. They can be manufactured with our without arch.
Eccentricity reduction
This reduction joints are used to join pipes with different diameters and the loss of the axial shaft center. They can be manufactured with or without arch.
Joint with one arch and flanges of different sizes
Similar to the joint with one arch, but its flanges are of different size allowing the connection to tubes of different size according the pipe system.
Joint with revolving flange
Expansion joint built with revolving flanges at the extremes. The special construction counts with steel rings to reinforce the contact with the flange.
Inner sleeve
This accessory is a sleeve with a van stone end or complete flange face, that made of hard rubber, metal or Teflon, that extends through the interior of the extension joint. It reduces wear on the joint sand smooth the flow reducing the turbulence. It is not recommended for thick fluids.
Joints with a stuffed arch
The arch can be stuffed with soft rubber, providing a smooth pipe. It is only recommended when necessary, since the absorption capacity decreases by 50%.
Joint with inner tube suitable to service
The inner tube can be manufactured with the most suitable material according to de containing fluid.
“U” type joints with or without flanges
“U” type joints are recommended for a total vacuum or a pressure of max. 25 PSIG and are normally used between turbines and condenser.
Joints with sphere type corrugation
This joint has an arch with big radius which gives it greater the movement absorption capacity over the traditional design. The design is also self-cleaning which eliminates the need for a stuffing in the arch.
Joints with sleeve extrems
Sleeve ends have the same inner diameter as the pipes outer diameter, where the joint is placed and fixed with clamps. The use is only recommended with medium pressure or vacuum, since air tightness cannot be guaranteed with clamps.
Rectangular joint
This joint fits rectangular flanges and their behaviour is similar to the circular ones.
