Sealing

 

 

 

 

 

The elastic lip of seal is tightly pressed against the outer surface of even an irregularly
-shaped pipe by means of pilot holes. The internal pressure of the pipe bears upon
the rear side of the lip so that pressure in-creases improve the sealing properties.
In the centre of the seal is a raised rubber stopper.
This acts as a stiffener for the seal when pipe contents are below at mospheric
pressure and separates the pipe ends from each other.
The waved form of the internal surface of the seal prevents it from being sucked into
the pipe when pipe contents are below almospheric pressure.

Installation

 

 

 

 

 

Normally, the YN-Multiflex coupling is placed over the end for one of the pipes to be
connected.
After this, the coupling is simply tightended to the torque shown for the coupling.
(See Fig.1)
To repair localized leaks, the coupling casing is opened and the casing and sealing
park is removed. The seal is cut away and the center stopper is stripped off.
After this, the casing with seal is installed around the leaking welded joint or other
leaking point, and tightened as befor. (See Fig.2)
