With the amount of rolling motors on the market, there are a lot of variables to consider. However, one of the most common questions is around torque control, setting torque, and when it’s not needed for a job.
Surface finish plays a critical role in determining the performance and longevity of a part. However, it’s important to understand what materials can be burnished and how material impacts the finish that can be achieved.
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.
Tube patterns describe how the tube holes are distributed through a tube sheet. Manipulating tube patterns helps increase flow but these modifications can create challenges for tube expansion.
Dunn Heat Exchanger, Inc., a fabrication company located in Texas City, Texas, offers heat exchanger cleaning, decontamination, repair, and fabrication services in the highly competitive shell and tube market.
Elliott Tool Technologies, a USA based tube tool manufacturer, announced the launch of an all new assisted tube rolling system.
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.
Elliott Tool Technologies, a USA based tube tool manufacturer, presented its annual Gustav Wiedeke Award to The Dow Chemical Company at Heat Exchanger World Americas 2023. This award highlights the importance of customer participation in Elliott’s new product development process and encourages others to collaborate with Elliott to overcome industry challenges.
Tube cleaning is a necessary part of any vessel maintenance process. Depending on the application, water, gases, and other caustic chemicals can be run through the unit. Overtime, these compounds cause deposit build-up inside of the tubes, resulting in a loss in operating efficiency.
To get the best performance out of a vessel it’s important that it maintains necessary operating capacity. While there are several preventative maintenance procedures that can prolong the life of the vessel, eventually a decision on retubing or replacing the unit will need to be made.
