[Technical Column] When to Replace? Guidelines for Replacing Gaskets for Stainless Steel Containers

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, it is important to clearly communicate not only safety and workability but also "what kind of initiatives the site is undertaking." Hyper CLT mats are civil engineering mats that utilize wood CLT. They look significantly different from conventional steel plates, so when laid at site entrances, viewing routes, or material yards, they create a strong visual impact. In particular, during inspections by clients, site tours, and public open days for local residents, the use of wood, environmental considerations, and the application of new technologies can be conveyed in a "visible form." Additionally, they are lightweight and easy to install and remove, and they offer practical benefits such as reducing glare and metal noise, as well as CO2 fixation. Hyper CLT mats are registered with the Ministry of Land, Infrastructure, Transport and Tourism under NETIS as "TH-250021-A." They combine wood, NETIS, civil engineering, and CLT, making them a new temporary material that can impressively convey the initiatives of the site.

Hotron Inc. has launched its new product, the "Vehicle Count Sensor CCS3"! This product is a ceiling-mounted sensor that combines infrared and radar technology. It reliably detects vehicles in both directions with a single unit, accommodating traffic during congestion and vehicle passing, thus achieving efficient occupancy management in large parking lots. Additionally, it can be utilized for exit warning purposes in addition to vehicle counting, contributing to the safe and smooth operation of parking facilities. 'Features' - Improved detection performance against changes in road surface during rainy weather by using both infrared and radar. - Equipped with IP67 waterproof and dustproof performance, making it effective even in salt damage areas. - Various settings can be configured from a dedicated app (for Android devices), with current settings easily understandable at a glance. - The base dimensions are the same as the previous model "CCS2," allowing for smooth replacement of existing equipment. *For more details, please refer to the product information, catalog download, or contact us.*

Metal cracks are one of the concerns in equipment maintenance operations. Conventional welding repair 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" and "secondary damage." Hinode Water Supply Equipment Co., Ltd.'s "Mechanical Stitching Method" is a new technique that allows for metal crack repair 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 made even in environments where open flames cannot be used. Since no heat is applied, the disassembly of equipment is minimized. For more details, please contact us or download the catalog.
