Learning from Causes: Measures Against Packing Water Leaks and How to Choose Correctly

Learning from Causes: Measures Against Packing Water Leaks and How to Choose Correctly

In addition to the three checkpoints on-site, we will also introduce examples of improvements!

Is work on-site being halted due to issues like 'leaking from the packing' and 'despite multiple repairs, the cause cannot be identified'? In this article, we will thoroughly explain the three main causes of packing leaks and provide specific countermeasures that can be implemented from a practical perspective. We encourage equipment maintenance personnel and site leaders to make use of this information. *For detailed content of the column, please refer to the related link.

What is the difference between FF and RF gaskets? A professional explains their shapes, uses, and how to choose them.

Introducing important points to avoid failure in gasket selection!

Gaskets are essential for flange connections in piping, but did you know there are two types called "FF" and "RF"? These two types have significantly different shapes and areas of sealing surfaces, and choosing the wrong one can lead to serious issues such as leaks. In this article, we will clearly explain the fundamental differences between FF gaskets and RF gaskets, their respective features, and how to choose the right one. *For more detailed information, you can view the related links.
