Flexible Joint Flange is a special flange connector used to connect flexible joints (flexible connectors) with pipeline systems, achieving a transition connection between rigid pipes and flexible connectors. The product is widely used in pump inlet/outlet, pipe compensation, vibration reduction and noise reduction, thermal expansion compensation and other applications, effectively absorbing vibrations, displacements and thermal expansion of pipeline systems, reducing stress concentration and extending pipeline system service life. Flexible joint flanges are typically used with flexible connectors such as rubber flexible joints, stainless steel bellows flexible joints, etc., to form a complete flexible connection system. The flanges are manufactured using high-quality materials with excellent pressure resistance and sealing performance, ensuring connection reliability.
