Nichias: This is a comparison table for fluid compatibility of Vulcargas gaskets. Asbestos joint sheets have versatile properties that allow them to cover a wide range of practical applications due to their excellent heat resistance and pressure resistance. However, as the transition away from asbestos progresses, a certain degree of categorization for usage applications will be necessary. The alternative flow shown below is merely a guideline, but it serves as an example of systematic categorization. Please use it for selection purposes.

This product is a type of semi-metallic gasket commonly referred to as a spiral wound gasket. Due to its unique structure, it can be used under high temperature and high pressure conditions similar to metal gaskets, while demonstrating excellent sealing performance. It is widely adopted in piping and equipment across a broad range of fields. Please feel free to contact us when you need assistance. 【Features】 ■ A spiral structure made by alternately layering a V-shaped cross-section metal strip (hoop) and a non-metallic cushioning material (filler), which are then securely welded at the beginning and end of the spiral. ■ Four types of shapes are available to match the gasket seating of the target flange: basic shape, with inner and outer rings, with outer ring, and with inner ring. *For more details, please download the PDF or feel free to contact us.

We would like to introduce our steam piping joint sheet 'TOMBO No.1155'. Thanks to our unique formulation technology, we have successfully minimized the creep at high temperatures, which is a drawback of PTFE, allowing for excellent sealing performance even under high temperatures. Since PTFE is the main material, degradation at high temperatures is minimal, and it can be re-tightened as needed, ensuring safe and reliable long-term use. 【Features】 ■ High compressive strength ■ Difficult to break when installed on flanges ■ Can be installed safely *For more details, please download the PDF or feel free to contact us.

"TOMBO No.1133" is a white high-temperature resistant sheet gasket made primarily from PTFE and alumina. Since it uses alumina, which has excellent chemical resistance, there is no need to differentiate gaskets based on the type of fluid, such as acids or alkalis. Additionally, it can withstand high temperatures and high pressures, making it suitable for use in areas where electrical insulation is required. 【Standard Sizes】 ■Thickness: t1.5, t2.0, t3.0 ■Size (mm): 1270×1270 (standard) *For more details, please download the PDF or feel free to contact us.

"TOMBO No.1120" is a non-asbestos joint sheet that can cover the practical application areas of asbestos joint sheets. It is a black sheet gasket that contains no asbestos, reinforced with aramid fibers primarily made of expanded graphite. It uses oil-resistant rubber as a binder. Please feel free to contact us when you need it. 【Features】 ■ Usable for saturated steam at 2MPa ■ Excellent heat resistance, steam resistance, and corrosion resistance ■ Resistant to scratches and highly flexible *For more details, please download the PDF or feel free to contact us.

We would like to introduce our general piping joint sheet 'TOMBO No.1995'. This is a brown non-asbestos joint sheet that contains no asbestos, made by adding inorganic fillers to inorganic fibers and aramid fibers, with oil-resistant synthetic rubber as a binder. The sealing thickness is 1.5mm, and the shape used is a ring type (FR). In cases where maintenance is difficult, vortexes and other methods may be used. 【Usage Range】 ■ Water-based fluid pressure resistance: 2MPa / Maximum operating temperature 183℃ ■ Oil-based fluid pressure resistance: 2MPa / Maximum operating temperature 183℃ ■ Gas-based fluid pressure resistance: 1MPa / Maximum operating temperature 183℃ *For more details, please download the PDF or feel free to contact us.
