Sudden welding ruptures on minor branches
Unexpected trips for gas leakage
Forced maintenance every 3 months due to fast wearing of PTFE piston sealing elements
Rod packing elements life was <1000 hours
Ruptures on cooler and HP piping (every 2-3 months)
High vibrations since first start-up
User wanted to change driver type from gas engine to electric motor
Extremely fast rings consumption
Frequent piping support failure
Impeller destroyed twice at first Start-up
Turbine trip during start-up on both units. Severe damage to the rotors due to rubbing against the stator
After a maintenance stop, Turbine could not start due to high vibrations (both low and high frequency)
Explosion of the Gas Turbine cabinet
OEM no longer available. User wanted to extend the operating life of this old unit by upgrading machine monitoring
Performance loss (efficiency and flow rate) caused by increased clearance between impeller and casing due to corrosion
Gas leakage between upper and lower semi-casings
Performance improvement through upgrading of an old unit which has at present:
Δp on a temporary strainer quickly rose to ~1.3 bar
Catastrophic failure of stirrer supporting bearing caused heavy damage to the reactor wall
Old PtP lubrication system with recurrent issues
Unexpected compressor shutdown
Root Cause Analysis based on:
Knocking sound from cylinder head
Foundation corruption
Complete turn-key project
Recurrent high vibration on a variable speed compressor
Two cylinder-distance piece tie-rods found broken
Increasing vibration trend suggested machine stop and inspection: resilient element found heavily damaged
Major compressor failure prevented by substituting resilient element
