Introduction: 1. During the construction of flexible rubber joint pipeline engineering, it is necessary to keep it in natural condition, and it is not allowed to cause artificial deformation of goods during installation. When the pipeline material is resistant to acid, alkali, oil, high temperature and other materials, a gear higher than the pipeline pressure should be used

1. Flexible Rubber joint When the pipeline is in the condition of artificial deformation, the pipeline should not be installed due to human factors. When the pipeline material is acid and alkali resistant, oil resistant, high temperature and other materials, the connector with a gear higher than the pipeline pressure should be used.

2. The flange connecting rubber joint shall be gate valve flange or flange conforming to GB / t9115.1 (RF).

3. All normal materials available for the flexible rubber joint are ordinary water with a temperature of 0-60 ° C. In case of unique substances such as oil, strong acid and alkali, high temperature, other corrosion and hard color, the relativity should be adopted, and the rubber joint with special resistance to raw materials should not be blindly used in series or universality.

4. Flexible Rubber flexible joint When the pump is used in the import and export trade, it should be located on the side of the water spring, and the metal material reducing joint should be installed between the water spring and the water spring, and it should be installed in the large size of the variable diameter.

5. When the pipeline offset is greater than the large compensation of the connector, the total number of connectors should be increased to offset the parallel plane. It is forbidden to adjust the deviation of the pipeline so that the tensile strain deviation and error of the interface can not be exceeded (telescopic, offset, offset, etc.). See the table below for the actual installation data.

6. For water supply and drainage of high-rise residential buildings or suspended in the air, the pipeline shall be fixed on the support, fixed support or anchor frame, and the joint shall not bear the net weight and radial force of the pipe itself, otherwise, the joint shall be equipped with anti pulling equipment (its bearing capacity must exceed the radial force of the pipeline).

7. When installing the rubber joint, the extruder screw of the anchor bolt shall extend to both sides of the connector, and the anchor bolt of each flange inner hole shall be continuously and evenly tightened according to the top angle charging method to avoid pressure deviation.
