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.
Over the past several decades, Elliott Tool Technologies and Monaghan Tooling Group have partnered together to provide quality precision metal finishing tools. We are pleased to announce that Elliott and Monaghan have made the decision to transition sales and marketing to Elliott Tool Technologies, effective January 1, 2024.
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.
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.
When it comes to removing tubes, there are many different options to choose from. Hydraulic or automated pulling options can be a great way to speed up the job, reduce tube sheet damage, and improve operator ergonomics. However, before selecting a pulling package, it’s important to consider the vessel type, tube condition, and space constraints
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.
