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 universal expansion joint (CCU) is a expansion joint consisting of two series—mounted bellows connected by an intermediate pipe. It perceives axial, shear (transverse) and angular movements simultaneously.
The universal design is used in areas with complex movement paths, where one type of compensation is not enough. It can be equipped with tie rods to limit the stroke.
OnePROM manufactures a control panel for the parameters of the object: diameter, pressure, temperature, and types of compensated movements. Selection is based on a questionnaire.
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.
Perceives axial, shear, and angular movements simultaneously. Two bellows with coupling elements. 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.
The control cabinet is manufactured to meet the parameters of the object: nominal diameter 50-800 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.
