Retubing a vessel can be very extremely difficult depending on the type of vessel, how long the tube has been in service, and how efficient the initial expansion was. From support sheet bending to broken tubes, there are many issues that an operator can face during the removal process. Here are some tips & tricks you can use to overcome these common tube removal problems.
Tube pullers grip and pull the tube out from the tube sheet. There are a variety of tube removal tools available and each one has a specific use. Review the quick guide below to make sure you select the right tool for the job.
The American Society Of Mechanical Engineers (ASME) develops standards to provide consistency and ensure public safety and reliability. While these codes are not always required, they have been widely adopted and implemented across many industries. As a result, it is important to be knowledgeable and aware of these standards prior to beginning a job.
Single roll beading expanders simultaneously expand and bead the tube ends in firetube boiler applications. This tool accomplishes the creation of a pressure-tight tube-to-tube sheet joint, and a beaded tube end, by utilizing the natural feed force built into the expander to push the beading roll against the end of the tube while expansion is taking place.
Elliott’s Single Roll Beading Expander saves Keller & Associates on labor costs as compared with the manual method of using an air hammer and beading tool which takes three operations instead of one.
"Approved by all my operators as effective and easy to use as opposed to a rotary tool, cutting cleaning time by at least half." - Chris Lewis, Maintenance Manager
The design of the wet back boiler can be frustrating for Boilermakers due to the limited access to install tubes in the combustion return area of the boiler.
