FLEXIBLE EXPANSION JOINT
In 1980, the industry’s first ball type flexible expansion joint made of ductile cast iron SUPER FLEX was developed. It soon became the standard for the ductile cast iron made ball type flexible expansion joint; thus, contributing to the safety of the lifeline. Also, its popularity has grown enough to break the sales record of more than 100,000 units being sold.
The Menshin Bender is a quake absorbing joint for facility piping. Due to its integrated design of a ball joint and a flexible pipe, it can track large horizontal displacements. Its recoilless force balanced mechanism restrains thrust generation; thus, greatly reducing the use of concrete thrust blocks.
