Increase Tool Life On Tough Materials


As end users strive for increased heat transfer efficiency, customers are often tasked with building vessels that will withstand heavy use and the test of time. This often results in the use of more wear resistant tube sheet and tube materials, such as Inconel, Hastelloy, and Duplex Stainless Steel. While exotic materials often mean longer tube life, they can take a big toll on expander tool life.

Cutting Lands in Spool Bore Valves


From forklifts to land excavators, valves are used to regulate the flow of fluid through the machine, impacting the functionality of the machinery. For these large pieces of equipment to handle fine movements and adjustments, it’s important that the grooves and lands inside of the valve body are cut precisely.

Tube Sheet Grooves and How They Impact Expansion


Grooved tube sheets are the standard in most shell and tube heat exchanger applications. Providing both leak protection and improving the tube-to-tube sheet joints, grooves play an important role in prolonging the life of a tube and the efficiency of a vessel. However, in few applications where grooves are not required, there can be challenges during the tube expansion process.

What is Burnishing?


While traditional finishing methods are effective, in many cases, these processes require multiple operations and set-ups to achieve the desired finish. Burnishing is an effective and efficient alternative that often eliminates the need for secondary processes entirely.

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.
