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.
Anatomy of A Tube Expander
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.
Expanding X-ID® Boiler Tubes
In order to increase efficiency and lower operating costs, many boiler makers are switching to X-ID® enhanced tubing. While X-ID® tubes are beneficial for the end user, they can be challenging to install.
Increase Tool Life On Tough Materials
As end users strive for increased heat transfer efficiency, customers are often tasked with building vessels that will withstand heavy use and the test of time. This often results in the use of more wear resistant tube sheet and tube materials, such as Inconel, Hastelloy, and Duplex Stainless Steel. While exotic materials often mean longer tube life, they can take a big toll on expander tool life.
How To Size An Expander For Center Tube Sheet Expansion
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.
Overcoming Challenges When Expanding Small Tubes
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.
