This product is a bellows used in the Versa Joint (JIS30K type). Compared to bellows of the same plate thickness, it has a multi-layer structure, which provides excellent low reaction and flexibility, and there are no usage restrictions based on flow rate. It has been widely adopted in applications such as large gas turbines, the Seto Ohashi water supply line, and exhaust transfer for escort ships, all of which operate under harsh conditions such as "use at high temperatures," "expansion and contraction due to thermal expansion," and "significant vibrations from equipment and wind," and it has been used for a long time. 【Features】 ■ Almost no aging degradation ■ The bellows do not expand when internal pressure is applied ■ No usage restrictions based on flow rate ■ In the unlikely event that a crack occurs inside the bellows, the fluid will not burst out suddenly, allowing for continued use until a replacement can be delivered ■ There is no need for a reinforcing ring to increase pressure resistance, eliminating concerns about interference with the bellows during vibration and displacement absorption *For more details, please refer to the related links or feel free to contact us.
