Following advises are however to be taken into consideration in order to obtain a good performance and prolonged of the expansion joint.

Fixed points

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:
姗¤啝鎺ラ牠鐨勫弽鍔涜▓绠楀叕寮忓�備笅锛�
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

Installation

The turnable metal flanges make installation easier and eliminate twist.

The low inherent rigidity of Sungkiang expansion joints make for easier accommodation of installation dimensions.

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.

Maintenance instructions: observe whether the rubber joint is over stretched and keep the rubber joint in normal length every month.

Mounting
瀹夎��
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.

Tightening must be progressive and crosswise in diagonal sequence with bolting pressure evenly distributed.

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

Note:If the bolts and nuts are tightened too strongly, the sealing face might be crushed causing function!

Counter flanges
鍙嶆硶铇�
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).
