Not having a compatible tube plug material can result in leaks, costing hundreds of thousands of dollars or more in lost production and revenue. When plugging a “leaker” (leaking tube), it is good practice to use plugs that are the same or a compatible material to the tube in order to meet industry requirements and engineer specifications and avoid galvanic corrosion.
Getting the right tools for your application is critical in order to complete the job right the first time. One of the most overlooked factors when ordering tooling, is determining whether you have minimum wall or average wall tubing.
The Plant Manager had heard many product claims before from sales people saying how great their product performs. He was a bit skeptical, but agreed to a production trial to see if the results of the product are what Elliott is claiming.
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.
Cleaning tubes increases energy efficiency. Every tubed vessel (ex: boilers, heat exchangers, condensers, chillers, etc.) requires the surface of the tubes to be clean and scale-free to function efficiently. If deposits or scale are present, the flow through the vessel and the efficiency of the vessel decreases.
When it comes to selecting a tube plug, there are a variety of options and factors to consider: application, material, and the ID of the tube. The three main types of tube plugs offered are one-piece, two-piece, and mechanical.
Choosing the right expander to suit your needs.
Tube Expanding is the art of reducing a tube wall by compressing the O.D. of the tube against a fixed container, such as rolling tubes into tube sheets, drums, ferrules or flanges. To assure a proper tube joint, the tube wall must be reduced by a predetermined percentage.
