Steam Borescope Services

Borescope ScreenPAL Turbine Services, LLC. can give you the peace of mind of knowing the current condition of your steam turbine can be determined inexpensively with a borescope inspection.

PAL experts can internally observe, digitally record and diagnose the condition of such critical components steam path components, control valves, stop valves, diaphragms and packing. The IPLEX provides Stereo Imaging for precise measurement from any angle. Using the IPLEX Borescope System, PAL experts can determine the seriousness of cracks, foreign object damage (FOD) and steam path distortion. Damage can be measured to the nearest one-thousandth of an inch!!borescope_pic1

Cracks? Our Olympus stereoscope can measure a crack so you'll not only know its location and direction of propagation, but the length of the defect to within one-thousandth of an inch. The depth of any FOD indentations can be measured as well with this special feature.

Let PAL borescope your steam turbine, and our experts will report on metallurgical conditions of internal components. Digital photographs will be made available before the engineer leaves the site. Timely reports are delivered with representative photographs and analysis of defects and recommendations, typically within two weeks of the on-site inspection.

Peace of Mind is Worth the Price of a Borescope Inspection
