This QB Spheroid pipe joint has high compensation rate, no blank plate force
Brief introduction
QB Spheroid pipe joint is also called spheroid compensator. Mainly rely on spheroid angle displacement to adsorb or compensate pipeline one or multi directions lateral displacement. This kind of compensator should be used as twin, a single spheroid compensator do not have compensate capability. It could be used as universal joint for pipeline.
This compensator has high compensation rate, no blank plate force. Its acting force to fixing bracket is small. The seal use injectable combination seal technology to realize long time reliable seal.
