Laser Profilometry applied to advanced inspection of tubular forms
LOTIS® (Laser Optic Tube Inspection System) applies laser profilometry as the technique to gather measurements. Qi2 developed the first LOTIS system in 1985 for the US Navy to inspect the internal surface of boiler tubes. Following its first application, Qi2 has repeatedly applied this technique to benefit many industries – and today continues to find new applications to explore.
How Laser Profilometry works
Laser Profilometry is a non-contact, non-destructive inspection technique that utilizes a low-powered laser to profile the surface of an object. The number of lasers applied within the measurement probe and the scanning speed determines the number of data points captured with each scan. LOTIS probes are engineered to fit the geometries and ID characteristics of the forms inspected. Below are a few examples of probes engineered by Qi2.
Examples of LOTIS Application
|Chemical and Refining||Reformer Tube Inspection System||Delivered improved creep strain detection in boiler and catalyst reformer tubes.
|FTIS® – Furnace Tube Inspection System||LOTIS combined with ultrasonic in a smart pig. The FTIS detects failure mechanisms in fired heater furnace tubes.|
|Automotive and Marine||QC-20 Hose Inspection System||The standard in the automotive industry for measurement of curved and straight hose sections.
|Industrial Parts||QC-10 Small Parts Scanner||Custom built system to measure heater blades in a small consumer product.
|Oil and Gas||QC-40 Stator Inspection System||Measures complex geometries of metal stators and elastomeric linings used in Moineau-type pumps.
|API Thread Profiler||The first automated profiler of API thread forms, (developed for Quest Metrology).
