Introduction: Install the rubber joint on the pipe correctly to prevent the rubber joint from stretching too much. The rubber joint shall be installed as soon as possible after the support frame is installed. After installation, the pipeline behind the rubber joint must be equipped with the correct guide support

Correct installation Rubber joint In order to prevent the rubber joint from stretching too much on the pipe. The rubber joint shall be installed as soon as possible after the support frame is installed. After the installation, the pipeline behind the rubber joint must be equipped with a pipe to guide the support bracket to the support point pipe correctly. When locking the flange screw, please apply the right torque so that the rubber joint can extend to its large movement and maintain the surface layer of the product. When installing the screw, please put the screw from the flange outlet of the flange to which the rubber joint is connected. The surface of external thread and nut shall not have sharp mouth.

Rubber pipe joint Installation instructions:
1. It is forbidden to install the rubber pipe joint over offset during installation.

]2. The pipeline needs fixed support or fixed bracket, and the force of fixed bracket should be greater than the axial force. During vertical and empty installation, the two sides of the product should be installed with opposite supporting frame and supporting support frame, so as to avoid stress breaking in work.

3. The mounting bolts should be symmetrically pressurized and tightened gradually to prevent partial leakage.

4. During installation, heat sources shall be eliminated and materials not conforming to the regulations of this rubber shall not be used.

5. It is forbidden to install the rubber joint over displacement during installation.

6. The installation bolts should be symmetrical, and gradually pressurized and tightened to prevent partial leakage.

When the pressure is about 7.1.6mpa, the foundation bolt should be installed with malleable pressure pad to prevent the anchor bolt from loosening during operation.

8. During vertical installation, both sides of the joint pipe shall be provided with vertical support plates, and anti pull off equipment can be used to avoid stress breaking during operation.

9. The installation position of rubber joint shall be free from pyrogen and active oxygen area. It is forbidden to expose to strong radiation source and apply substances that do not meet the requirements of this rubber

10. It is forbidden to cut the surface and protruding surface with sharp equipment when transporting, loading and unloading.

"Ten common problems" of proper installation of rubber joint

1、 Before installation, the appropriate model and specification shall be selected according to the pressure, interface mode, material and compensation amount of the pipeline, and the total number shall be selected according to the provisions of noise and noise reduction deviation.

2、 Pay attention to the adjustment of working pressure. When the pipeline causes instantaneous working pressure and exceeds the pressure, the joint with a gear higher than the pressure should be used.

In addition, when the pipeline material is acid-base, oil, high temperature and other materials, the joint with a gear higher than the pipeline pressure should be used.

3、 The flange of t912000 or t9115 flange shall be flange.

4、 Attention should be paid to the fact that the rubber joint bears a force at one time, for example, after the installation is stressed or before the rubber joint is re opened after long-term suspension, the bolt should be re pressurized and tightened before putting into operation.

5、 Pay attention to the temperature adjustment. All normal materials available are ordinary water with a temperature of 0-60 ℃. In case of special substances such as oil, strong acid and alkali, high temperature, other corrosion and hard color, the rubber joint with corresponding special resistance should be used instead of blindly following the trend or universality.

6 Flexible rubber joint When it is used in the import and export trade of centrifugal pump, it should be located at the side near the water pump, and the metal material reducing joint should be installed between the pump and the pump, and it should be installed at the large size of the variable diameter.

7、 When the pipeline offset exceeds or equals to the large compensation deflection and error of the joint, it is not allowed to exceed the degree (telescopic, offset, offset, etc.). See the table below for the actual installation data.

8、 For the water supply and drainage of high-rise residential buildings or suspended in the air, the pipeline should be fixed on the support, fixed support or anchor frame, and the joint should not bear the net weight and radial force of the pipe itself, otherwise the joint should be equipped with anti pulling equipment.

9、 When installing the rubber joint, the screw rod of the bolt shall extend to both sides of the joint, and the bolt of each flange inner hole shall be continuously and evenly tightened according to the top angle charging method to avoid pressure deviation. The screw joint should be tightened evenly with standard wrench. It is not allowed to add points with adding pole to make the movable joint slip, slip edge and fracture, and regular maintenance should be carried out to prevent loosening and leading to disc detachment or leakage.

10、 For example, in the application or storage of rubber joints, should prevent high temperature, active oxygen, oil and strong acid and alkali natural environment.

At the same time, considering the aging problem of rubber products, it is necessary to build a shading frame for outdoor or sunny and windward pipes. It is necessary to prohibit exposure to the sun, rain and wind erosion.
