Large rod horizontal metal bellows compensator mainly used to compensate axial displacement of the inner piping and the product itself lateral displacement length, with a piping design is simple, easy to install, large caliber large amount of compensation, to the space and flat piping The lateral displacement. Bellows belongs to a compensation components. Using their body of work stretching deformation effective bellows to absorb the dimensional change by the thermal expansion and contraction and other reasons arising from or compensation displacement pipelines, conduits, containers. It can also be used for noise damping. In the now widely used. ? First, the product structure characteristics: Large rod horizontal corrugated expansion joint consists of two bellows and long rod over the middle and large parts such as structure, it can absorb any lateral displacement piping plane. When the displacement of large spherical rod nut rotation around spherical washers, while the large trolley also has the ability to internal pressure thrust. Second, model: factory production DN100-8000mm pressure level 0.1-2.5Mpa three connections: 1, 2 flanged, take over the connection four-lateral compensation: 90-537mm
