Welding has become fairly common practice in pressure vessel fabrication and maintenance. From tube ends to plugs, welding can provide additional strength or sealing coverage if done correctly. When it comes to tube plugging, many customers are facing questions about plug materials and special requirements to ensure vessel specifications are met. In this article we will discuss the changes to the ASME code, material types and nomenclature, and impacts to the welding process.
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.
Confined spaces are one of the most common challenges boilermakers face during tube installation and maintenance. From squeezing into drums, to working in tight utility rooms, space constraints are present in all aspects of the job. In order to get the job done quickly and effectively, it’s important that operators have the proper tooling on hand. Using the wrong tooling can make the job harder and pose safety concerns.
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.
There are different ways to clean tubes, and the type of tube cleaning tools you use will depend on the application. Let's take a look at some of the most common kinds of tube cleaners:
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.
Plugging tubes are one of the most convenient ways to repair shell-and-tube types of heat exchangers. It can be an effective and reliable method to fix a heat exchanger when done properly. However, it could cause more harm than good if not executed carefully.
