When it concerns choosing a tube plug, there is a wide array of factors to consider. Tube leaks can take place in industrial boilers and condensers anytime due to multiple reasons. The formation of holes is the prime reason behind leaks in tube plugs. Holes are formed within the tubes because of deposit accumulation, dirt, corrosion, and the improper use of cleaning heads. Hence, tube plugging is a necessity across all industries. This also indicates that choosing the right tube plugs is vital to eliminate any leak of liquid or gas.
Tube Plugs: Types
When it concerns selecting tube plugs, one needs to be familiar with the available different types. Over the years, designs have evolved to ensure top-notch efficiency and optimal sealing function. The market is flooded with a wide variety, and based on one’s needs, the selection must be carried out. The three common types of tube plugs are:
- One-Piece Plugs
The tube plugs are primarily used in low-pressure containers or tubes.
- Two-Piece Plugs
Similar to one-piece plugs, two-piece plugs are also used in low-pressure tubes or containers. Compared to one-piece plugs, two-piece plugs offer a better secure sealing area.
- Mechanical Plugs
Mechanical tube plugs are considered the most efficient plugging solution. They have a wide sealing area and sealing potential. Additionally, mechanical plugs can be utilized in all pressure applications.
Tube Plugs: Material
Material is yet another vital aspect that must be considered when selecting tube plugs. It is best to pick the same material as the tube or one that is compatible. When an incompatible material is picked, several problems like galvanic reactions, rusting, and corrosion might occur. Incorporating compatible materials assures a similar coefficient and hardness of thermal expansion. This is vital because hardness influences the intensity of plugs to create mechanical seals. Similar thermal expansion hardness and coefficient ensure that plugs are not shifted when the temperature fluctuates during the startup and shutdown of a unit.
Tube Plugs: Size
Size is also a critical factor that must be considered when choosing a tube plug. A tubing plug that is either too small or big will fail to seal off a hole or a leak in the pipe or container efficiently. It is recommended to take accurate measurements before investing in a tube plug. Furthermore, it is better to get the help of an engineer to understand the precise size and dimensions of the plugs. Seeking help from an expert helps address common sizing problems and expected expansions.
Conclusion
When one is considering buying tube plugs for heat exchanger needs in industrial boilers and condensers, and other equipment, considering the factors mentioned above is applicable. Plugging the tubes is considered the most convenient and effective means to secure leaks and holes in industrial pipes and vessels. Depending on the application in the industrial sector, material, and size, the selection process becomes more accessible. Moreover, it is also necessary to use tube plugs to acquire the best seal in low-pressure, mid-pressure, and high-pressure circumstances.
