There are extreme conditions in the industrial world where the common knowledge of sealing materials does not apply at all. Ultra-high temperatures, ultra-high pressures, and ultra-high vacuum. To meet the supreme challenge of maintaining system airtightness under such conditions, the last bastion that exists is the 'metal gasket.' In this article, we will thoroughly explain why metal gaskets, composed solely of metal, can exhibit high sealing performance, their diverse shapes and principles, and the correct material selection and usage to fully harness their capabilities. *For detailed content of the column, please refer to the related links.

"When stainless steel pipes were used with carbon steel bolts, only the bolts rusted excessively. In the case of dissimilar metal connections in seawater piping, one of the metals became severely corroded." Do you have any experience with such "abnormal corrosion" of metals? It may not just be rust, but rather "galvanic corrosion." Galvanic corrosion progresses locally through a mechanism different from normal corrosion, and if left unchecked, it can lead to leaks from the piping, a decrease in equipment strength, and in the worst case, serious accidents. *For more details on the column, please refer to the related link.

Maintenance of machinery and equipment that has been in operation for many years. When I opened the flange after a long time, I found a deteriorated unknown gasket. Have you ever encountered such a situation? Moreover, it is not uncommon for that unidentified gasket to actually be an asbestos-containing gasket that was widely used in the past. Once celebrated as a "dream material" for its incredible heat resistance, chemical resistance, and durability, asbestos gaskets were active in various industrial fields. However, as the serious health hazards became clear, new manufacturing and use are now strictly prohibited by law. *For more details on the column, you can view it through the related link.

"I want a seal performance equivalent to a spiral gasket, but is there a gasket that is easier to handle?" "I want to ensure no leaks even in narrow sealing widths like those in heat exchangers." "I am looking for a highly reliable gasket that can be used stably for a long time under high temperature and high pressure." In sealing applications for plants, pressure vessels, heat exchangers, and more, balancing performance and ease of handling is an eternal challenge. Particularly in modern equipment where large diameters and complex shapes are becoming more common, there are increasing situations where conventional gaskets are difficult to use. To meet such advanced demands, we have developed the "Camprofile Gasket," which skillfully combines the strength and heat resistance of metal with the flexibility and sealing ability of non-metal materials. *For more details on the column, please refer to the related links.

"The sealing material around the boiler's combustion port becomes worn out due to heat." "The flange of the exhaust duct is significantly warped, and a sheet gasket cannot fill the gap." "When replacing the gasket in the high-temperature area, the adhesion to the flange is severe, making it difficult to remove." In high-temperature equipment such as power plants, incinerators, boilers, and various industrial furnaces, harsh thermal environments exceeding 400°C are commonplace. Gaskets used in such locations require a level of heat resistance that is incomparable to general sealing materials. However, at the same time, flexibility is essential to conform to the warping and irregularities of the flange surfaces unique to high-temperature equipment, and above all, safety to protect the workers is indispensable. *For more detailed information, please refer to the related links.

"The manhole gasket for the boiler, while the glass cloth rated for 400°C makes me a bit uneasy, the AES fiber rated for 800°C is over-spec and costly." "The large-diameter exhaust duct flange has a gasket that is too soft, making it difficult to install vertically." "The gap between the flange surfaces is narrow, and with a flexible gasket, it can bend during insertion." In high-temperature equipment, especially in manholes, inspection ports, and connections of boilers, drying ovens, and exhaust ducts, not only is "heat resistance" important, but "workability (handling performance)" becomes extremely crucial from the perspective of work efficiency and safety. In particular, when installing large-diameter gaskets vertically or inserting them into narrow flange gaps, gaskets that are too soft may lose their shape and require significant effort for installation. *For detailed content of the column, you can view it through the related link.

"I want to reduce costs for the boiler manhole packing." "I need a flexible gasket that fits the flange of the exhaust duct." "Is there an easy-to-use sealing material for a hot air line at around 400°C?" The selection of sealing materials for high-temperature equipment always requires a balance between performance and cost. In particular, in areas such as the inspection openings (manholes, handholes) of boilers and the connection points of exhaust and hot air ducts, where high clamping force cannot be applied and complete airtightness is not required, an over-specified high-performance gasket may not necessarily be the optimal solution. *For more details on the column, please refer to the related links.

"I want to use a safer RCF-free material for the boiler manhole gasket." "The exhaust duct reaches high temperatures close to 800°C, but there is distortion on the flange surface, making it impossible to seal with a sheet gasket." "For large-diameter high-temperature flanges, the gasket is too soft and loses its shape during installation." Power plants, incinerators, various industrial furnaces, and exhaust systems of diesel engines are subjected to harsh high-temperature environments that can reach 800°C. The gaskets used in these applications must not only have excellent heat resistance but also ensure material safety to protect the workers, as well as flexibility to conform to the distorted flange surfaces typical of high-temperature equipment. However, at the same time, especially for large diameters, ease of handling during installation is also an important factor that cannot be overlooked. *For more details on the column, please refer to the related link.

"Large-diameter manhole gaskets are difficult to install vertically, and I always struggle with them. The flange gap is narrow, and with a soft gasket, it bends during insertion. A safe gasket that is RCF-free is needed for high-temperature areas close to 800°C, but I want something that is easy to handle." In high-temperature equipment, especially for sealing manholes and inspection ports in boilers, incinerators, and large ducts, not only is "heat resistance" and "safety" important, but "ease of installation (handling)" becomes extremely crucial from the perspective of work efficiency and ensuring safety. To respond to the voices from the field that prioritize "high-temperature resistance," "RCF-free safety," and above all, "ease of handling during installation (rigidity)," Nichias Corporation has designed the high-performance woven fabric gasket "TOMBO No. 1420-S (Super Manhole Gasket-S)." *For detailed content of the column, please refer to the related link.
