The exact values of the compensating capacity and the construction length depend on the standard size and are determined by selection according to the questionnaire. Isolation ППУ — according to ГОСТ 30732.
Other diameters and versions are manufactured to order.
СКУ.ППУ/PE is a bellows compensation device in polyurethane foam insulation with an outer protective shell made of polyethylene. The polyethylene shell provides hydraulic insulation protection during underground duct-free laying.
It is used on underground heating networks, including in wet soils. Insulation according to ГОСТ 30732, on request — with SOD. Welding connection, the joints are insulated simultaneously with the pipeline.
OnePROM manufactures СКУ.ППУ/PE for the parameters of the object. The exact values of stroke and construction length are based on the questionnaire.
We accept a questionnaire or a laying scheme, select the design and parameters.
We calculate the compensating capacity and prepare a quotation.
We produce a device for the parameters of the facility with quality control.
We ship to site and, where required, provide installation, installation supervision and commissioning.
СКУ in ППУinsulation with a protective polyethylene (PE) shell. For underground duct-free laying of heating networks, including in wet soils.
