I produced a rectangular corrugated compensator (HJX type), also known as the rectangular compensator, rectangular bellows, with axial, lateral, angular compensation, widely used in central air conditioning pumps, fire pumps, pump life to import and export, effectively reduce host vibration, noise absorption piping, protective equipment, extend equipment life, a durable, high temperature, high pressure, corrosion, environmental protection and other advantages. Effective solution to the old-fashioned soft rubber joints brought unsanitary, easy to aging, pressure unstable, delamination tear, blasting and other adverse factors, to solve the worries of the pumping station. Rectangular bellows Model: according to user needs can be rectangular bellows pressure level: 0.01-0.1MPa rectangular corrugated compensator connection: ① flanged; ② take over the connection type.
