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.

The "Bulker No. GF300" contains no rubber at all, making it a joint sheet for steam piping that does not undergo thermal degradation. It can also be used at high temperatures. By utilizing a flexible resin binder, we have improved brittleness and susceptibility to damage compared to expanded graphite sheet gaskets. Please feel free to contact us when you need assistance. 【Features】 ■ No hardening degradation due to heat or aging ■ Since hardening does not occur, re-tightening is possible ■ Applicable to a wide range of fluids *For more details, please download the PDF or feel free to contact us.

This product is a metal gasket developed based on a rational design for high-temperature and high-pressure flange sealing materials. It maintains stable sealing performance over a wide range and does not easily cause leakage or damage even under harsh conditions such as thermal cycles, pressure cycles, and thermal pressure in piping systems. Please feel free to contact us when you need assistance. 【Features】 ■ Withstands high-temperature and high-pressure conditions, maintaining excellent sealing performance even when usage conditions change rapidly. ■ Low adhesion to flanges makes cleaning easy and allows for smooth gasket replacement work. * For more details, please download the PDF or feel free to contact us.

"Vulcan No. 6500" is a sheet-like gasket material made by mixing a special rubber-based binder with organic and inorganic fibers and a small amount of filler, followed by rolling and vulcanization. It does not contain asbestos fibers, making it suitable as a non-asbestos alternative to asbestos joint sheets. Please feel free to contact us when you need assistance. 【Usage Range】 ■ Water-based fluid pressure resistance: 2MPa / Maximum operating temperature 160℃ ■ Oil-based fluid pressure resistance: 2MPa / Maximum operating temperature 160℃ ■ Gas-based fluid pressure resistance: 1MPa / Maximum operating temperature 160℃ *For more details, please download the PDF or feel free to contact us.
