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.
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.
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.
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.
The design of a chiller can pose some challenges when it comes to tube installation and maintenance. From the center tube sheet to tube enhancements, special considerations need to be made when choosing the correct tooling for the job.
Elliott Tool Technologies, a USA based tube tool manufacturer, announced the launch of a newly redesigned Grooving & Serrating tool. Equipped with a reusable wear pad the new mandrel design allows for metal chips to escape easily, reducing damage to the mandrel and tube sheet hole.
Pneumatic tools are utilized in a variety of tube tool applications from expansion to cleaning. While the power source is often determined based on operator preference, there are some applications where air may be required or preferred over electric. However, to get the best life and performance out of pneumatic tooling, it’s important that the quality of air and the amount used is regulated correctly.
It's no secret that tube leaks or failing hydro is a huge headache for organizations. When it comes to tube installation, proper expansion can be the difference between an expensive repair bill and a long-lasting vessel.
Similar to a shell and tube heat exchanger, air coolers are made up of stacked finned tubes with header or water boxes on either end of the vessel. While air cooler maintenance can be challenging, there are a few tips and tricks that can help make the process easier.
