Multi-Stage Rotors

Multi-Stage Rotors

BWC Technologies has been servicing multi-stage turbine and compressor rotors for over twenty-five years. When BWC Technologies receives a multi-stage turbine rotor or compressor rotor, digital pictures are taken, a visual inspection is performed, the shaft is polished, and a complete dimension and concentricity report is created.  In addition, the rotor is blasted cleaned and non-destructively tested for cracks. BWC Technologies will re-take digital pictures of any problems that need to be addressed.

At this point, we take the findings and provides a detailed quote to our customer. Our customers are free to schedule a time to come tour our facility in the Pocono Mountains of Pennsylvania to see their rotor first hand and to review our quote with us in person or to discuss the quote over the phone.
