Description

СКУ.ППУ/OC — bellows compensation device in ППУ-insulation with an outer shell made of galvanized steel. The shell protects the insulation from atmospheric and mechanical influences during overhead installation.

It is used on aboveground and elevated heating networks. Insulation according to ГОСТ 30732, on request — with SOD. Welding connection.

OnePROM manufactures СКУ.ППУ/OTS for the parameters of the object. The exact values are based on the questionnaire.

How we work
