General characteristics

Almost all types of compensators are manufactured with fittings for welding, except for rubber compensators. The material for manufacturing the connecting branch pipe of the compensator for welding can be, depending on the type of device: stainless steel, galvanized steel, steel grade 20, as well as alloy steel grades required by the customer. Axial compensator type KSO is designed to compensate for thermal expansion on straight sections of pipelines, as well as inaccuracies in their installation.

Axial compensators are characterized by

- Nominal internal bore diameter;

- the value of the working target stroke (angular degrees, millimeters);

- permissible maximum pressure (bars, atmospheres, pascals);

- operating temperature, taken into account in the calculations of the working stroke values;

- material (ordinary structural steel, stainless steel, alloy steel) and type of connecting fittings (flanged, threaded, welded);

Operating conditions of axial bellows expansion joints KSO

First of all, the performance characteristics must be determined by the target tasks that the axial bellows compensator must perform. During operation, it must:

- withstand the maximum operating pressure, as well as the test pressure to which the pipeline is subjected;

- do not reduce the pipeline capacity;

- easy to install and repair;

- do not reduce the values of target parameters below the permissible limit under the influence of mechanical vibrations and temperatures.

All characteristics of axial compensators are given for a temperature of 20 0 C, as well as for a thousand complete compression-extension cycles.

- working environment pressure: not higher than 125 kg/cm2.

- working environment: steam, water, oil products, gases, etc.

- operating temperature range: -260 +800 C°.

The required value of the working stroke is achieved by the number of bellows corrugations.

Axial flange compensator (with blind/floating flange)

The axial flange expansion joint with a floating flange greatly simplifies installation, since the flanges can be easily and freely rotated to ideally fit the bolts to the holes, as well as when replacing equipment. The axial flange expansion joint with a blind flange allows a more rigid connection to be achieved by welding to the bellows.
