In chemical plants, high sealing performance and durability are required to handle corrosive and highly reactive fluids. Fluid leakage can lead to plant shutdowns and safety risks. Therefore, gaskets that provide stable sealing performance even under harsh conditions are essential to support the safe operation of equipment. The spiral gasket D1000 is designed to meet the stringent demands of such chemical plants. [Usage Scenarios] - Flanged connections of reactors, heat exchangers, pumps, valves, etc. - Sealing of corrosive fluids and high-temperature, high-pressure fluids - Ensuring safe plant operation and reducing maintenance costs [Benefits of Implementation] - Excellent resistance to reactive fluids - Maintenance of stable sealing performance over the long term - Improved plant reliability due to reduced leakage risks

We would like to introduce a case where we manufactured a D1000 spiral gasket (thickness 4.5mm) for an oval opening (300mm×400mm, seal width 25mm) based on the customer's drawing. It prevents leaks of high-temperature and high-pressure steam or hot water. In this case, we produced a V-shaped cross-section metal hoop and filler, which is the sealing material, with high precision using a dedicated winding machine. The spiral gasket is a high-performance semi-metallic gasket that is rationally designed for high temperature and high pressure applications. We can also manufacture spiral gaskets with special shapes based on the customer's drawings and specifications. Please feel free to contact us. 【Case Overview (Partial)】 ■ Material: D1000 ■ Product: Spiral gasket ■ Shape: Oval (300mm×400mm, seal width 25mm) *For more details, please download the PDF or feel free to contact us.

Our company offers a "Carbon Sheet" made from acrylic fibers as a spark protection cover sheet, woven from fibers that have been carbonized through heat treatment. This carbon cloth is made from 100% carbonized fibers, providing non-combustibility and fire resistance. It has excellent heat resistance and flame retardancy, and it only glows red under high temperatures without burning or melting. Additionally, we also offer a lightweight "Spatter Sheet" that is coated on both sides with special silicone on fiberglass. 【Features of Carbon Sheet】 ■ Made from 100% carbonized fibers ■ Carbon cloth with non-combustibility and fire resistance ■ Lightweight, making it easy to transport and work with on-site ■ No toxic gases are emitted, and it does not cause skin irritation *For more details, please download the PDF or feel free to contact us.

The "D7000-ST" is a PTFE sealing tape that can withstand temperatures from -100°C to 260°C, making it particularly suitable for seals in high-temperature areas. It is very easy to attach and detach. Since PTFE is a self-lubricating adhesive, screwing in and removing is simple, and it does not cause seizing. It can be used with acids, alkalis, and chemicals without dirtying your hands, and it finishes cleanly and easily. Additionally, it is not affected by the fluid being used and does not cause contamination. Due to PTFE's excellent chemical resistance, it can be used in piping for water, steam, oil, and chemicals. 【Standard Size】 ■ Thickness: 0.1mm ■ Width: 13mm ■ Length: 15m *For more details, please download the PDF or feel free to contact us.

We would like to introduce the "Magnesium Anode" that we handle. Through electrochemical action, it prevents corrosion of the hot water tank body.

The stable operation of boiler equipment is the foundation of various industries. On the other hand, due to the harsh environment of high temperature and high pressure, consumable parts such as water level gauges, valves, and piping flanges require regular inspections and prompt replacements. However, when selecting parts, challenges such as "not being able to arrange genuine parts in time," "not knowing compatible parts from other manufacturers," and "not knowing where to order custom gaskets" are always present. To everyone involved in the maintenance and upkeep of boilers, we have prepared the Daiko Co., Ltd. 【Boiler Parts Catalog】 (free PDF), which condenses the necessary parts selection, technical data, and a "manufacturer comparison chart" into one book. *For detailed content of the column, please refer to the related links. For more information, feel free to contact us.

Daiko Co., Ltd. handles a variety of "special parts and packing for boilers." We offer a lineup that includes the "reflective water level gauge," which is widely used as a water level gauge for land and marine boilers, as well as "packing for sleeve gauge cocks" that maintain airtight structures, and "packing for boiler manholes." 【Product Lineup】 ■ Reflective water level gauge ■ Packing for sleeve gauge cocks ■ Sleeve packing ■ Gland packing ■ Round glass tubes, etc. *For more details, please refer to the PDF document or feel free to contact us.
