Achieving excellence in construction with 800℃ heat resistance and rigidity! A thorough explanation of AES woven fabric gaskets.

Achieving excellence in construction with 800℃ heat resistance and rigidity! A thorough explanation of AES woven fabric gaskets.

Thorough explanation of why No. 1420-S possesses the unique characteristics of being particularly "strong and easy to handle" among high-temperature woven fabric gaskets!

"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.

600℃ heat-resistant and rigid construction! Glass fiber woven fabric gasket.

600℃ heat-resistant and rigid construction! Glass fiber woven fabric gasket.

Why No. 1400-NA is chosen among high-temperature woven fabric gaskets, particularly for its "rigidity (strength)" is thoroughly explained!

"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.

Escape from asbestos gaskets! Criteria for selecting non-asbestos substitutes.

Escape from asbestos gaskets! Criteria for selecting non-asbestos substitutes.

A thorough explanation of why asbestos gaskets were special and why a simple replacement is impossible!

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.

Bulkar No. 8590 Series | Thorough Explanation of "Clean Tight"

Bulkar No. 8590 Series | Thorough Explanation of "Clean Tight"

A thorough explanation of why clean tights are commonly adopted as a standard in many utility lines!

"I want to choose a reliable gasket for the plant's steam and cooling water lines while keeping costs down." "The joint sheet cannot withstand it, but the highest performance graphite filler is over-spec." "Is there a spiral wound gasket that is easy to install and economical for medium and low-pressure piping?" To ensure stable operation of the plant, it is essential to maintain not only the main process lines but also the utility lines such as steam, cooling water, hot water, and compressed air. In these lines, the balance between "cost performance" and "stable reliability" is prioritized over extremely high performance. The product developed to accurately meet such on-site needs is the standard semi-metallic gasket manufactured by Vulcan, the "Vulcan No. 8590 Series (commonly known as CleanTite)." *For more detailed information, please refer to the related link.

The roles of the core components "hoop" and "filler" of spiral wound gaskets.

The roles of the core components "hoop" and "filler" of spiral wound gaskets.

Based on the official product documentation of Nichias Corporation, a thorough explanation of the "hoop" and "filler" that determine the performance of spiral gaskets!

"Why can spiral wound gaskets withstand high temperatures and high pressures?" "What do the differences between graphite, PTFE, and fillers signify?" "What should be considered when selecting the material for the hoop?" The "spiral wound gasket," which boasts overwhelming reliability under harsh conditions such as in power plants and petrochemical plants. The secret to its excellent sealing performance lies in its intricate spiral structure, which alternates between a V-shaped metal strip "hoop" and a cushioning material "filler." These two components serve as the skeleton and muscles of the gasket, and correctly understanding and combining their respective roles and materials is the key to effectively utilizing spiral wound gaskets. *For more detailed information, please refer to the related links.
