Mitigating Glitch on Shafts Using Diamond Burnishing Tool


Rotors or shafts used in steam and gas turbines, turbo generators and compressors, or any large motor, have to work within set standards for runout to ensure efficient and safe operation. If excessive runout is not eliminated during the manufacturing process, the motor would have to be disassembled and the shaft reworked. This can be a time consuming and costly process and one the motor manufacturer would want to avoid.

How To Retube A Locomotive Boiler


Historically, many railroad companies used steam locomotives for transportation. Today, most steam locomotives are reserved for private rails, museums, and other charity organizations. As these systems age, they present several unique maintenance challenges that can arise due to the design and location of these units. Understanding the composition of locomotive boilers, as well as the maintenance needs, can make restoration jobs a little bit easier.

Increase Tool Life On Tough Materials: Benefit Of Tapping Spears


In recent years, the use of exotic materials in heat exchanger tubing has become a lot more common. While these materials are great for working in tough conditions, they can have be very challenging to work with as they often require more tooling and job time. This is especially true in tube removal where pulling spears are used. Tapping spears have become an effective way to overcome many of these issues.
