SUIKEN Ductile Iron Flexible Expansion Joint – SUPER FLEX

FLEXIBLE EXPANSION JOINT 1) Double ball type ductile iron flexible expansion joint shall be provided as indicated on drawings and capable to satisfy the following properties after installation without jeopardizing the coupling properties. A) The angular deflection shall be provided within the ball parts of flexible expansion joint. Angular deflection of each ball part shall not be less than 15 degrees for up to DN600 and 12 degrees for DN700 or above. B) Flexible expansion joint shall be capable of free rotation along centre axis. C) Ball parts of flexible expansion joint shall not change its inside cross section providing a smooth flowing surface without any protrusions at maximum subsidence to avoid clogged. D) Restraining force shall be Class A: 3DkN for each size. E) Fitting bolts and nuts shall be of stainless steel. Ball part, however; shall carry no bolts and nuts. F) Rubber gaskets for flexible expansion joint shall conform to BS 6920 for the portable water supply and shall be of enough sealing ability. G) All internal surfaces shall be factory coated with minimum 300 microns thick epoxy powder coating, while the external surface shall be factory coated with minimum 0.08 microns thick synthetic resin coating. Additional external protection shall be provided by means of polyethylene sleeves. 2) Expansion capability shall be provided in the middle part of flexible expansion joint. Additional expansion sleeves shall be available and easily added as needed. 3) Flexible expansion joint shall have a structure which increases its expansion and contraction capabilities when its subsidence capability is increased as per requirement. 4) Moving part of flexible expansion joint shall be equipped with stopper bolts attached to it to prevent expansion during shipping. These stopper bolts shall be designed such that they shear off when a pulling force is applied to the joint. 5) The connection of flexible expansion joint to adjacent pipe shall be of an approved jointing system being able to fully transmit the designed angular deflection and axial movement to the flexible expansion joint.
