Tube expanding is a technique used to create a secure connection between a tube and tube sheet, by compressing the outer diameter against a fixed surface. This process ensures a leak-proof joint that is crucial for the proper functioning of heat exchangers and other pressure vessels.
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.
Tube expansion can be challenging regardless of the application. From inconsistent wall thicknesses to exotic materials, a lot of factors can influence the quality of an expansion. In smaller applications, there can be some additional complexity to the process which makes choosing the right expander more critical.
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.
Boiler tube removal can be an extremely difficult process and the method used will vary depending on the application. The amount of expansion, as well as, the age of the tube and whether or not it was welded will all impact the removal process. Despite the challenging nature of removal, there are a few tips that can help make this tough job a little bit easier.
Do you know what is retubing, and why is it important? Retubing is the process of replacing an aging or damaged tube in a heat transfer vessel. It is considered a routine maintenance procedure and can help improve the reliability and longevity of the vessel.
