Rubber expansion joint - short description

Compensators rubber pipelines are made of wear-resistant rubber and high-strength fabric power layers with a diameter of up to 1200 mm. Length up to 1000 mm. With flange connection. The flange dimensions are made in accordance with GOST 12819-80; 12820-80, 12822-80 or in agreement with the customer. It is possible to manufacture rubber compres- sors with different compensation values ​​(both linear and angular) deformations. Rubber compensators damp the water hammer, prevent the development of electrochemical corrosion.
