[Technical Column] How can this chemical be stored? ~ The best packing for chemicals ~

Explaining the differences between packing, gaskets, and O-rings, as well as the materials and properties of packing essential for sealing stainless steel containers, and how to select them!

When using stainless steel containers, there are various requirements for the containers depending on their intended use. Sealing components play a crucial role when sealing the containers or piping from the containers to manufacturing equipment. Here, we will explain the various sealing components commonly used in our stainless steel containers, focusing particularly on gaskets. However, what is described here is a general introduction to commonly known items. There are many other types of sealing components depending on the materials and applications. When considering containers, we will propose suitable sealing components that match your purposes. We hope this explanatory document will serve as a reference when considering stainless steel containers.

• Stainless steel container

A stainless steel container that allows for identification and management of contents with color packing!

Identification and management can be done using the color of the packing, allowing for differentiation with colored packing in cases where the contents may impart odors to the packing. Due to the colors, it is easier to detect if the packing is chipped and has mixed into the contents. The packing comes in four colors (red, blue, green, and white) and is used by attaching it to the rim of the container. It is ideal for temporary storage of powders and liquids that are sensitive to moisture and outside air, as it is a sealed stainless steel tank. With a handle, it allows for smooth transportation and movement when using a dedicated cart (KM series). The corners of the bottom have an R structure, making it difficult for dirt to accumulate, thus ensuring good cleanliness and hygiene. When combined with a transparent acrylic lid [AF], it is also possible to distinguish the color of the packing while the lid is on.

• Stainless steel container

A stainless steel container with a PTFE gasket that is excellent in chemical resistance and can store solvents that can damage rubber gaskets!

This is a catch-clip type storage container that replaces the silicone packing included with our stainless steel tank [CTH] with PTFE packing, enhancing chemical resistance, solvent resistance, and oil resistance. Due to the stainless steel tank, it is resistant to rust and can be reused multiple times. It has a handle for smooth transportation and movement when using a dedicated cart (KM series). The corners of the bottom are designed with an R structure, making it difficult for dirt to accumulate, which improves cleanability and hygiene.

● This is a leak testing device for small electronic components that does not use fluorinated inert liquids (PFAS-free). ● There is no longer a need for unstable visual confirmation through liquid immersion testing. It adopts a quantitative testing method that allows for stable pressure leak testing. ● It is a tabletop leak testing device specifically for gross leaks, with accuracy equal to or greater than that of liquid immersion testing. ● The detectable range is approximately 1×10⁻² Pa·m³/s to 1×10⁻⁶ Pa·m³/s (varies depending on the target product). ● It is suitable for sealed structures ranging from a few millimeters to a maximum of 80 × 70 mm.
