PURPOSE: To simultaneously prevent propagation of vibration of piping and propagation of pulsation of fluid flowing in the piping.
CONSTITUTION: A vibration control pipe joint is composed of an annular ring- shaped vibration control rubber 2, an orifice 3 whose outer peripheral part is held by an inside diameter part of this vibration control rubber 2, vibration control rubber support parts 5 formed in a flange shape in connecting end parts of both piping 10 so as to sandwich the vibration control rubber 2, bolts 4 and nuts 8 to fasten both vibration control rubber support parts 5 to sandwich the vibration control rubber 2 through rubber packing 9. Short cylindrical parts 5t are formed in outer peripheral parts of the vibration control rubber support parts 5, and collision damper rubbers 6 are installed and arranged on its end surfaces.
