V type Seismic Expansion Joints

Seismic applications allow for movement of adja¬cent sections of a structure at building joints or occasionally where piping goes from one building to another. The Vee is anchored close to and on either side of the separation. When it is between adjacent buildings, the location of the anchors depends on the space between the buildings and the rigidity of the pipe. The Vee may be in the space between buildings with a pipe anchor in each building or anchored in one building and guided in the other with an anchor further down. Piping and equipment connections shall be protected against seismic damage by the insertion of braided flexible hose Vee assemblies rated for ±4” (100mm) seismic motion in all planes. Should the application include ±6” (150mm) thermal movement or thermal movement alone, install the Vee so the thermal move¬ment is axial. All submittals shall include a recognized test report,covering the full range of the specified movements at the operating pressures. Forces required to move the Vees shall not exceed the Mason values below. Vees shall have a minimum burst pressure of four times their rated pressure. Vees in steel lines shall have stainless hose and braid. Copper lines, bronze hose and braid. Guiding and anchoring shall be as recommended by the manufacturer. 60° Vees shall be as manufactured by Mason Industries, Inc. Submittals shall include Movement-Force Test Reports.
