An expansion joint acts as a piston by the forces arising from the internal pressure.To prevent the pipes from damage they are to be properly anchored in order to take care of these reaction forces (Fr).

The Reaction force of an expansion joint is calculated by the following formula:

Fr = Q x P x 0.01
Fr = reaction force in kN.
Q = effective cross sectional area in cm2.
P = actual pressure in bar or kp/cm2

The expansion joints shall be easily accessible and open to regular supervision. Lt is recommended to let the expansion joints work in compression rather than stretching. Torsion is not permitted.

Mounting
锟斤拷锟絙
In order to provide the movement capabilities indicated indicated in the technical specifications,the assembly bolts should be mounted with bolts heads towards expansion jint body.(1)
If this is for any reason impossible,ensure that the threaded bolts project as little as possible(no more than 2 or 3mm)to avoid damage to the body.

The design of the expansion joints secures a sealing to the counter flange. That is why no sealing gasket is required.

Counter flanges

It is very important for the safe operating and life expectancy of the expansion joint to make a proper installation of the counter flanges(Fig. 2 to 5). The sealing face of the counter flange must be machined smooth and cover most of the rubber sealing face(or at least 60%)to ensure agood sealing(Fig.2).
