Ｎｅｗ Ｓａｆｅｔｙ　EARTH-PROOF PIPING SYSTEM   　

Dodge3 Joint is the land-mark earth-proof piping system which is arranged 3 kinds of metal bellows (Dodge Joint) at 3 points of L-shape piping and absorbs relative displacement for three dimensions direction occurred at earth-proof bed.

Earthquake - Proof Structure

With earthquake-proof equipment building and basement will be isolated not to transmit earthquake vibration direct to building. In earthquake- proof structure there would be occurred relative displacement by earthquake energy between building and basement and you need the new piping system for the life line in the building absorbing relative displacement occurred by earthquake against installed piping.

["Ｄｏｄｇｅ Ｊｏｉｎｔ"] New type of metal bellows developed for earth-proof piping system as “Dodge3 Joint” absorbing relative displacement occurred on life line and making the absorbing area compact. “Dodge3 Joint” Compared with conventional one absorptivity for angular displacement is more than 3 times ( The test was made by us) We use 2 types of “Dodge Joint” , one is Hinge type “Dodge Joint” which makes it possible to absorb one-way angular displacement and the other, Gimbal “Dodge Joint” which makes it possible to absorb 360 degree displacement (oscillating) .

■Simple Design Specification and Standard 　　 ●Volume of earthquake-proof will be decided upon fitting arrangement of each “Dodge Joint” 　　 ●Low reaction force without stabilized support 　　 ●Complete reversion to neutral position 　　 ●Changeable to earthquake-proof piping system for existing “L”shape fixed piping with our “Dodge3 Joint” 　　 ●High reliable piping design is possible with strength calculation ■Space saving and simple installation 　　 ●Effective use of space is possible without earthquake- proof roller and big stage 　　 ●Simple installation, all you have to do is arrange “Dodge Joint”with same length at 3 places. 　　 ●Beautiful installation in integral part with piping 　 ■Available for cooling medium, gas, drinking water, oil, chemical, and many other fluid and pressure

Remark）Displacement reaction shows Maximum figure. The weight of system shows total weight of each “Dodge Joint” and each weight of intermediate pipes and wheels. Please inform us regarding earth-proof volume other than 500 mm we are prepared detail of design data and manual. ●Above specification shall change for improvement without notice.
