? Pulverized coal pipeline three to compensate Introduction: coal pipeline three to bellows mainly for axial, angular compensation; dual-type structure can be used for axial and lateral compensation. Features high temperature, no leaking powder, no accumulation of dust, small displacement stiffness. One: Overview of the pulverized coal pipeline three corrugated compensation; special three-dimensional pulverized coal pipe bellows is designed for pulverized coal pipeline design of a special compensation, bellows for 1Cr18Ni9Ti or SUS304 material manufacturing, using a hydroforming process multilayer can compensate for axial, angular, lateral displacement synthesis of various orientations. II: Features: Product has a strong resistance to abrasion, with large amount of compensation, product performance, and long life, and many other advantages in one, so praised by users.
