Mechanical plugs are designed to expand radially when inserted into the tube, creating a secure fit. They can be expanded using tools like wrenches or hydraulic pressure. These plugs come in various designs, including single-sized plugs, multi-sized plugs, and inflatable plugs.
The Pop-A-Plug® image below system is a mechanical tube plug to seal leaking or degraded high-pressure heat exchanger tubes. The design ob-jective was to produce a fast and simple to in-stall mechanical tube plug with the same or bet-ter installed stability than a friction fit or welded plug.
We offer a variety of tube plugs for use in heat exchangers and boilers to keep them up and running. Whether it’s mechanical tube plugs or one-piece plugs, our products are made with quality materials so they are durable and can withstand different pressure requirements.
At times when it is not possible to use Mechanical fit tube plugs, standard friction fit tapered plugs may be used following this procedure and with reliability engineer or maintenance manager’s approval.
Our heat exchanger tube plugs feature quality silicone that can withstand temperatures up to 500°F. These tube plugs help seal leaks in tube bundles inside heat exchangers. They’re inserted into the affected tube, effectively isolating it from the liquid or gas flow.
Mechanical Plug: A mechanical plug is designed to expand inside the tube, creating a secure mechanical seal. This method is suitable for higher pressure applications as the seal is formed inside the tube end.
This article goes through three methods you can use to plug tubes in heat exchangers. Mechanical Plug. Method is usually installed using a hydraulic system. It is more appropriate for situations where friction-fit tapered plugs aren’t suitable due to various pressures, temperatures, environments, and specific conditions.
rmbsales.com Download• Pop-A-Plug® Tube Plugging System – for preparing and plugging leaking and/or degraded heat exchanger tubes. Suitable for service in operating pressures to 7000 PsiG (480 BarG) without welding or explosives. Identified in ASME PCC-2 (Article 312)* as a recommended mechanical tube plugging method
tanajib.com.sa DownloadPop-A-Plug® Tube Plugs take only minutes to install using a controlled force, which protects against damage to tube sheet ligaments and the adjacent tube sheet joints, extending the life of your heat exchanger and reducing costs when you need to re-tube. The system is available in a wide array of
Mechanical Plug: A mechanical plug is designed to expand inside the tube, creating a positive mechanical seal. Because the seal takes place inside the tube end, it can be used in higher pressure applications.
