The operational problems of steel and gray cast iron trunk pipelines become more and more difficult over their
operation time due to insight into corrosion and incrustation. The companies operating them are faced with the
choice of building new ones or administering existing renovations. On the example of 3 different completed
investments of different diameters pipelines, pipelines, the cost of their renovation was assessed.
Renovation 1 is Ø500 and Ø 800 pipelines, renovation 2 is Ø200 to Ø 400 pipelines, renovation 3 is Ø300 and
Ø 450 pipelines. Renovation technologies used were throwing cement and using Seartex-Liner H2O and Phoenix
Double Jacket sleeves. The prices for the renovation of 1 meter of the gray cast iron pipeline DN800 and DN500
using the CIPP UV sleeve (Seartex-Liner H2O) were 1760 PLN and 1100 PLN. The price for the renovation of
1 meter of the DN500 steel pipeline using the Phoenix Double Jacket process was 975 PLN. The price for the
renovation of 1 meter of steel pipeline DN600 using the cement lining process was 412,96 PLN. Therefore,
comparable investment implementation costs can be incurred using the CIPP UV (Seartex-Liner H2O) and Phoenix Double Jacket Process methods. It should be emphasized that the hydraulic properties of the given pipeline renovations have been improved.
