Quality and experience
General Project Energy is aimed at manufacturers and users of alternator groups, gas turbines, steam, hydroelectric turbines, large engines and heavy duty industrial machinery. We build and rehabilitate bearings, runners, bushings and components with white metal inserts and other anti-friction alloys, with a dimensional range from 20 to 2000 mm.
Our staff enjoys decades of specific experience, we are able to offer suitable solutions and specific engineering for new or old special components to be rehabilitated or reconstructed by means of reverse engineering, carry-overs by centrifugation, gravity bath or drop-by-drop torch carryover or TIG.
Below are some examples of processes, for more info we are available at the email info@gpeitalia.com
Overhaul after failure
After the failure that occurred on this DN90 bearing, the customer came to us for the refurbishment of the MB90 UNI4515 white metal lining. Remetalled and restored in 10 days!!
Stop & Go
The electric motor that mounts on this support needed to restart soon, 3 weeks for the complete rehabilitation of this Ø175 bearing with 220 mm height.
The white metal coating was made with MB90 UNI 4515 by centrifugation.
The final tests, in addition to the dimensional check, were VT, PT and UT. All made by a UNI EN ISO 9712 level II technician
Overhauled to the core
For this bearing D450 L940, intended for hydroelectric generation plant, we had to restore the white metal coating. The particularity of this intervention is the replacement of the coil of the heat exchanger which is drowned directly in the white metal.
The white metal coating was made this time with MB85 UNI 4515 by centrifugation. The final tests, in addition to the dimensional check, were surface roughness, non-destructive tests VT, PT and UT by a UNI EN ISO 9712 level II technician. Finally, the coil was tested under pressure to verify the absence of leaks.
Guide bearing overhaul
We have overhauled a guide bearing and a guide + thrust bearing, both 180 mm in diameter. After removing the old coating, we applied MB90 UNI4515 white metal. The quality control plan for the supply included visual and dimensional checks before and after the coating. On the finished pieces dimensional control and non-destructive tests VT, PT and UT. Non-destructive tests are always performed by a UNI EN ISO 9712 certified second-level technician.
Delivery time? 4 weeks.
