Why Won’t This Tube Expand
When expanding heat exchanger tubes, achieving the proper wall reduction is crucial for a secure and leak-free seal. Sometimes, however, tubes fail to expand sufficiently, hindering the integrity of the vessel. This article outlines common causes and troubleshooting steps for incomplete tube expansion.
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.
Do I Need Torque Control?
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.
Fabrication Company Reduces Expansion Cycle Times by 80% With Parallel Pin 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’s New Rolling System Offers 30% Tube Expansion Savings, Guaranteed

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.
