| Type | Axial, flanged connection |
| Movements absorbed | axial (compression/stretching) |
| Nominal diameter, DN | 50–1400 mm (up to 3000 mm to order) |
| Working pressure, PN | up to 25 kgf/cm²; higher to order |
| Medium temperature | up to +450 °C |

Exact compensating capacity and face-to-face length depend on the size and are determined during selection from the completed questionnaire.
Other diameters and versions are manufactured to order.
Bellows axial flange expansion joint (КСО.F) is a type of axial expansion joint with a flange connection to the pipeline. It perceives temperature elongations due to compression and stretching of the bellows.
The flange design simplifies installation and disassembly: the expansion joint is bolted without welding in place, which is convenient for maintenance and replacement. The flanges are welded or pivoted, according to ГОСТ.
OnePROM produces КСО.F for the parameters of the object: diameter, pressure, medium temperature and required axial stroke. We carry out the selection, calculation and delivery. Please send us a questionnaire for selection.
We receive the questionnaire or specification and select the type and parameters.
We calculate the compensating capacity and prepare a quotation.
We manufacture the expansion joint to project parameters under quality control.
We ship to site and, where required, provide installation, installation supervision and commissioning.
Axial expansion joint with flange connection — for quick installation and maintenance without welding on the pipeline. Used in: heating networks and heat supply, steam pipelines, process pipelines, hot water and HVAC systems, boiler houses and central heating plants, oil and gas facilities.
КСО.The product is manufactured according to the parameters of the object: nominal diameter 50-1400 mm (up to 3000 mm on request); working pressure up to 25 kgf/cm2; higher on request; temperature up to +450 °C; working medium — water, steam, gas, petroleum products and other non-aggressive media.
