The project was executed in Industrial Facilities of Hellenic Petroleum Aspropyrgos Attica during the Turn Around 2015 and included the following works:

1. Work Unit U-3100

     Erection of scaffolding for all unit operations.

     Construction of foundations to support heat exchangers M-3106 C/D.

     Modifications of existing steel structures for the installation of new exchangers M-3106 C/D.

     Installation of two (2) new heat exchangers M-3106 C/D.

2. Work Unit U-3200

       Erection of scaffolding for all unit operations.

       Prefabrication and erection of new steel structure and modification of existing for the installation of the new heat exchanger M-3209C, anchoring and concreting of the new metal structure.

       • Fabrication and installation of new metal pedestals for exchangers         M-3226 A/B and modification of existing pipe-rack for the interconnecting piping of M-3226 A/B with the U-3200.

       Installation of three (3) new exchangers M-3902C, M-3226A/B.

3. Work Unit U-3400

       Erection of scaffolding for all unit operations.

       Construction works to strengthen the existing foundation to support the new exchanger M-3401D.

       Installing new heat exchanger M-3401 D.

4. Work Unit U-4600

       Erection of scaffolding for all unit operations.

       Construction of new bases for placing new heat exchangers M-4611C and M-4621.

       Installation of two (2) new exchangers M-4611C & M-4621.

In addition to the above key works in all units performed the following tasks:

       Piping works which included the dismantling of pipelines, installation of new and modification the existing for connecting the new exchangers as well as construction and installation of all necessary supports.

       Quality control: X-Rays, PT and PWHT of all the alloy steel welds. Hydraulic test with pressure from 8 bar up to 131,55 bar. Overall executed 25 tests.

       Installation of new control valves and valves, new safety valves and new instruments of pressure and temperature indication.

       Sand blasting - coating of all pipes, steel structures and supports.

       Insulation of exchangers and piping.

       Restoration units and pre-commissioning operation.

Total diametrical inches all units 6.121,50” (carbon steel 5.430 '', alloy steel 475'', stainless steel 216,50'')

Total erection weight for pipes 37.859,97 kg. Diameters from ½ '' - 16 '' Total weight for steel structures of all units:

-       Metal construction 34.074 kg.

-       Metal supports 6.450 kg.

All project materials were provided by the owner except the steel construction materials and insulation materials.

The above project was carried out in parallel with the project “Maintenance work in the furnaces L-3101 & L-3901 during Shut Down 2015 in Industrial Facilities of EL.PE Aspropyrgos”.
