Description:
Rubber expansion joints, also called rubber compensators, are flexible connectors made of natural and/or synthetic elastomers and fabrics. If necessary, internal metal reinforcement materials can be used. These materials are designed to relieve thermal movement and piping system stress caused by mechanical vibration.

Single ball rubber expansion joint
Double ball rubber expansion joint
Flange connection rubber expansion joint
Threaded rubber expansion joint
Feature:
1. Good displacement compensation ability, capable of axial, lateral and angular
displacement.
2. Low noise, good vibration damping and corrosion resistance.
3. High pressure resistance, good elasticity, good displacement effect and simple

Single sphere rubber expansion joint is mainly used for reducing vibration, noise, good flexibility and easy to use.Single sphere rubber expansion join, also known as single ball rubber joint, rubber expansion joint, single ball connector ,shock absorber, pipeline shock absorber, is a kind of pipelinejoint with high elasticity, high air tightness, medium resistance and climate resistance.

The Ozdekan EXpansion Joints are waterproof expansion joints that allow absorption of the deck movements. These joints are manufactured with rubber elements and restrained to the structure with proper anchor bolts.

The reinforcing metal profiles made of steel are completely inserted and vulcanized to the rubber. This process is a total guarantee against corrosion and allows a longer life to the product.

The rubber compound, too, has been intentionally formulated to resist the oil, grease, petrol, salt and sand, without besides, suffering premature ageing phenomena due to sun rays, salt and snow.

All the joints follow the deformations and movements of the structure (the movement can exist with every skew angle from 0° to 90°) by shear deformation of the rubber elements.

Anchor bolts, made of steel and protected with anticorrosion treatments, absorb the elastic reactions and all the other kind of mechanical solicitations.

The joints are also able to compensate height difference or vertical movements. This characteristic is very important in all the cases where load and movement conditions can cause relative vertical movements. The joint series is manufactured by Ozdekan since 2006.

Main advantages:

Simple and linear design with few elements
Low height of the profile
Total impermeable
Easy assembling eitheron concrete structure
Suitable for the replacement of existing joint
Easy and quick to be replaced
Good resistance to vehicles sliding
Vertical movements absorption
The joints are supplied in variable length elements depending to the joint type. A joint line consists in fact of many units joined together with a groove-and-tongue junction welded with special glue. The joint fixing is obtained by chemical anchors; the nuts are locked using a dynamometric key so that permanent compression strength is given to the joint. Stainless steel anchors may be provided on request. In that way the horizontal forces, due to breaking of vehicles and to the reaction that rubber opposes to the joint deformations (shrinkage, creep, thermal variations etc.), are transmitted by friction between the rubber and the concrete. The joints can be assembled on a metallic infrastructure. The joints of bigger movements with four upper grooves are manufactured in order to prevent the lifting of the elements during the contraction. These devices guarantee the adhesion of the elements to the structure and the noiseless of the traffic.

Features
DMTflex Teflon expansion joint are used primarily in fluid conducting systems as resilient connections and tremor barriers. They are designed to compensate for mis-alignment, to absorb expansion and contraction and to isolate vibration and shock. They are also frequently used to reduce stress on fragile mating flange.
