Whether you are a buyer, a technician or an engineer, selecting the right condenser tube plug for repair work, whether for a specific job or continuing repair work in particular makes and models, there are a few important aspects to these plugs that must be taken into consideration. This is especially true for low-pressure condensers because there are many options available. The following are a few questions that need to be answered.
Is a tapered plug the right type?
There are three main types of plugs that you can select from, and the tapered plug is the simplest and most common. This is a single piece that narrows from one end to the other. This type is a good fit for any tube that is low pressure. You simply hammer it to the inside of the tube. In most applications, you will likely need to weld the plug to the tube. However, this carries the risk of damaging a nearby tube. But they are simple to install, and there is the benefit of not being precise in the plug's size.
Is a two-section plug a better type?
If there is any concern about the quality of the seal, you may want to consider using a two-section plug. This type of plug, obviously, has two sections, but it is secured at the opening of the tube by a large ring that divides the plug. The insert is tapped into the tube through the inside of the section that is inserted into the tube. Not only does this create a strong connection, but there is less stress on the inside of the tube, so the plugged end will last longer. To use this type of plug, you will need to know the exact inner diameter of the tube.
Is a mechanical plug the best option?
Although not every condenser tube plugs supplier supplier carries mechanical plugs, they are often the best choice for repairing condenser tubes. They are often available for high-pressure application, they can be used for low-pressure applications too. Basically, they are screwed inside the tube by using a torque wrench. The serrated edges of the plug provide a superior seal for the plug. They are removed with the use of a common slide hammer. These plugs are not available in the wide range of sizes that the other two types of plugs are found.
Both the one and two-section plugs will require tapping to install them. However, because the two-section plug provides a better seal, you may not need any welding. A mechanical plug provides the best seal, but not every supplier carries them. With both the two-section and the mechanical plug, the inside diameter of the condenser tube is critical. In addition, you should take care to match the tube metal or alloy to the plug that you are ordering.
