Matters needing attention

1. When installing flexible rubber joints in pipelines, they must be in a natural state, and do not artificially deform the product.When the pipeline medium is acid and alkali resistant, oil, high temperature and other special materials should be selected higher than the pipeline working pressure of a gear.

2. Flanges for rubber joints shall be valve flanges or flanges conforming to GB/T9115.1(RF).

3, flexible rubber joints normal applicable medium is the temperature of 0-60°C of ordinary water, special media such as: oil, acid and alkali, high temperature and other corrosive and hard conditions, should choose relatively due to the special resistant material rubber joints, not blindly string or universal.

4, flexible flexible rubber connector used in the pump inlet and outlet, should be located at the water spring side, and between the water spring should be installed in the metal diameter connector, and installed in the diameter of the large diameter source.

5. When the pipe displacement is greater than or equal to the maximum compensation of joints, the number of joints shall be increased to parallel displacement. It is strictly forbidden to make joints in the ultimate deflection displacement and deviation state in order to adjust the out-of-tolerance of pipes, not to exceed the limit (expansion, displacement, deflection, etc.).

6, high-rise water supply or suspended water supply, the pipe should be fixed in the hanger, bracket or anchor frame, and can not let the joint bear the weight of the pipe and axial force, otherwise the joint should be equipped with anti-pull device (its bearing force must be greater than the pipe axial force).

7. When installing the rubber joint, the bolt screw should be extended to the outside of the joint, and the bolt on the end face of each flange should be tightened evenly and repeatedly according to the method of diagonal pressure to prevent pressure deviation.Screw joint should be tightened uniformly with standard wrench, do not use the reinforcing straw to make the sliding wire, sliding edge and fracture of the joint, and should be checked regularly to avoid loosening and causing diskwork or water seepage.

8. The rubber soft joint shall be re-pressurized and tightened before it is put into operation after the initial pressure (such as pressure test, installation, etc.) or before it is restarted after long-term disuse.

9, use or store rubber soft joints, should avoid high temperature, ozone oil and acid and alkali environment.Use in the outdoor or wind to the sun pipe should be built sunshade frame, and prohibit storm sai, rain, wind turbidity.It is forbidden to paint and wrap insulation materials on the joint surface.Due to the aging of rubber products, timely inspection and replacement.

10. Flexible rubber joints shall not exceed the displacement limit during installation.

11. Install bolts symmetrically and tighten them gradually under pressure to prevent partial leakage.

12, flat, suspended, vertical installation of rubber joints, the actual working axial displacement pressure of rubber joints should be less than the support force of the pipeline, otherwise it should be installed anti-pull device to prevent the work of compression pull.

13. Rubber joints should be kept away from heat source. Ozone area is strictly prohibited.Insolate and use media that do not meet the requirements of this product.

14. During the transportation, loading, unloading and installation of rubber joints, it is strictly prohibited for sharp instruments to scratch the surface sealing surface.6: when installing products over DN200MM, please use the special flange of butterfly valve or small diameter flange, so as to avoid the phenomenon of flange pulling off, water leakage and water seepage after installation.If you have any other questions, please contact our company
