Offset shall be accomplished by the angular motion of a double sphere expansion joint bolted to each end of an intermediate steel pipe. Bracket each expansion joint with hinged steel connections. Hinges shall have a pin in a slot on both sides.
The piping on each end of the assembly must be securely anchored to accept a thrust of 1.5 times the operating pressure multiplied by the projected area of the pipe.
Specifications for the expansion joints shall be as Mason Industries Safeflex SFDEJ. The complete hinged assembly, Safeflex SFDEJ-HE at manufactured by Mason Industries Inc.
