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.
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.
