[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.

In civil engineering sites such as mountainous areas and construction sites, it may be necessary to use wooden boards on slopes or inclined access roads. Hyper CLT boards are civil engineering materials utilizing wood CLT, which can be laid not only on flat ground but also on sloped terrain. They can be used for temporary roads, access routes, heavy machinery entry paths, and measures against muddy conditions, creating a driving environment that takes advantage of the unique surface characteristics of wood. The 5×10 board weighs approximately 230 kg, and the 5×20 board weighs about 460 kg, making them lightweight and easy to install and remove even with small machinery, which is a notable feature for maneuverability in narrow sites. This wooden board is registered as a technology under the Ministry of Land, Infrastructure, Transport and Tourism's NETIS system as "TH-250021-A," and can also be utilized for safety measures and innovative ideas in public works.

Metal cracks are one of the concerns in equipment maintenance operations. Repairs using conventional welding methods can alter the base material around the crack due to heat, leading to residual stress and deformation, which always carries the risk of "crack recurrence" or "secondary damage." Hinode Waterworks Equipment Co., Ltd.'s "Mechanical Stitching Method" is a new technique that allows for the repair of metal cracks without applying heat. By using special bolts and reinforcement plates, the crack is physically removed without affecting the base material with heat. Repairs can be performed even in environments where open flames cannot be used. Since no heat is applied, the disassembly of equipment is minimized.

● The production time for cast prototypes can be shortened! Since model making is not required, the production time for prototypes, which previously took about a month, can be significantly reduced. ● Model costs can be reduced! By directly producing sand molds from 3D data, there is no need for model production costs. If changes to the model are necessary, they can be addressed by modifying the 3D data. ● Similar products with different shapes and dimensions can be prototyped simultaneously! Different products, such as similar shapes or varying dimensions, can be molded at the same time in one molding process. This allows for the verification of multiple types in a short period.
