Description

СКУ.M is a bellows compensation device in a steel protective casing. The casing protects the bellows from mechanical damage and directs axial movement; thermal insulation is performed with mineral wool or shell ППУ.

It is used on aboveground and ducted heating networks. The connection is either welded or flanged. Two—section design (2СКУ.М) - for increased axial stroke.

OnePROM produces СКУ.M for the parameters of the object: diameter, pressure, temperature and axial stroke. The exact values are based on the questionnaire.

How we work

Selection

We accept a questionnaire or a laying scheme, select the design and parameters.

Calculation and quotation

We calculate the compensating capacity and prepare a quotation.

Manufacturing

We produce a device for the parameters of the facility with quality control.

Delivery and installation

We ship to site and, where required, provide installation, installation supervision and commissioning.

Frequently asked questions

What is СКУ.M and where is it applied?

СКУ in a steel protective casing with thermal insulation (mineral wool or ППУ-shell). For above-ground and channel laying of heating networks. It is used for: above-ground heating networks, duct laying, main heating networks, central heating and boiler houses, steam pipelines, housing and communal services and heat supply.

What diameters, pressure, and temperature does СКУ.M allow?

СКУ.The M is manufactured according to the parameters of the object: nominal diameter 50-1200 mm (up to 3000 mm on request); working pressure up to 25 kgf/cm2; higher on request; temperature up to +200 °C; working medium — mains water, steam and other media of heating networks.
