Insulation Work – Replacement Of Thermal Insulation On The Overhead Network In Koronowo (Towards The K-20 Chamber) – Fragment Ii. The Subject Of The Order Is: Replacement Of Thermal Insulation On The Overhead Network In Koronowo (Towards The K-20 Chamber) - Fragment Ii. Scope Of Work: The Subject Of The Task Is The Replacement Of Thermal Insulation With Protective Coatings On The Overhead Heating Network 2Xdn200 (Scope Marked On The Map - Annex No. 7 To Swz), Carried Out In The Form Of One Of The Applied (Selected) Technologies Taking Into Account The Nature Of The Insulated Elements, I.E.: A) For Straight Sections Of The Pipeline, It Should Be Done By: O Applying A Steel Sheet Protective Jacket To The Service Pipe And Then Filling The Space Between The Steel Pipe And A Protective Polyurethane Foam Produced By A Foaming Unit, Or O Installation Of Pur Foam Shells And Then A Jacket Made Of Galvanized Steel Sheet In A Non-Combined Form, Or O Installation Of Prefabricated Insulation Shells Made Of Pur Foam, Combined With A Jacket Of Galvanized Steel Sheet, Constituting A Prefabricated Insulation System, Or O Installation Of Mineral Wool Mats, Covered With A Wire Mesh On One Side Galvanized Steel And Covering The Mesh Side With A Veil Of Dispersed Fibers, And Then A Protective Jacket Made Of Galvanized Sheet Metal, With The Steel Jacket Reinforced By Installing Additional Sheets Of Sheet Thickness. 2 Mm, Bent In The Shape Of The Jacket And Mounted Directly Under The Actual Protective Jacket In The Upper Parts Of The Pipeline. Construction Of An Additional Steel Support Structure To Hold The Entire Mineral Wool Insulation In Place. B) For Pipeline Fittings Such As Elbows And Pipe Bends As Well As Tees And Fittings, Insulation Should Be Used (Identical To The Insulation Of Straight Sections) By: O Direct Injection Of Insulation In The Form Of Polyurethane Foam, Produced By A Foaming Unit, Into Protective Elbows, Or O Installation Of Prefabricated Elements Made Of Pur Foam With A Galvanized Steel Sheet Cover, Or Alternatively, Insulation As Segmented Structures, With The Joints Having To Be Bonded Pur Foam Or Installation Of Insulation In The Form Of Mineral Wool Mats With A Galvanized Steel Sheet Cover. C) For Fittings, It Should Be Performed By: O Installing Insulation Using Pur Foam As An Insulating Material, With A Galvanized Steel Sheet Cover, And It Must Be Possible To Dismantle It Multiple Times Without Losing The Insulating And Functional Properties (Use Of Latches, Hinges) Or O Installing Insulation In The Form Of Mineral Wool Mats With A Galvanized Steel Sheet Cover, And It Must Be Possible To Ensure Its Repeated Disassembly Without Loss Insulating And Functional Properties (Use Of Latches, Hinges) D) For The Insulation Of Sliding Supports And Fixed Points, Insulation Should Be Used That Meets The Material Requirements Of Stwiorb - Annex No. 1 And Wt Annex No. 6 To Swz. Scope Of Works A) Dismantling And Disposal Of Existing Thermal Insulation Along With Protective Coatings; B) Anti-Corrosion Protection Of Pipelines At Least 25%
