Flexican bellows & hoses, an iso 9001-2000 certified company, provides metal bellows expansion joints in india. The company supplies gimbal expansion bellows. These bellows, which can permit angular rotation in any plane, consist of two pairs of hinges affixed to a common floating gimbal ring. When thermal expansion or other movements want to bend a pipe, in order to lower stresses, a controlled bending point can be added with a gimbal expansion joint. The hinged unit will limit bending to only one plane, and the gimbal will limit bending in all planes. The piping is always in tension because the pressure thrust is contained within the system. The main pressure thrust anchors are not required. Generally, only guides and intermediate anchors are needed. The full weight of the pipe between these expansion joints can be carried by them. Some of the salient features includes: absorbs angular rotation; conserves space; supports dead weight; eliminates pressure thrust forces; transmit shear and wind load; prevents torsion on bellows; no main anchors required; minimum guiding require; and low forces on piping system.
