Rubber Expansion joint with tie rod



FDamping and sound absorption:

1. The ball has a large damping on the rubber material, which can effectively buffer the vibration, suppress and reduce the mechanical vibration, and absorb the impact noise of the fluid.
2. Reasonable installation of vibration machinery and tie rod rubber joints can reduce structural transmission noise by 15 to 25 decibels.


Anti-stress:

1. Applicable to internal pressure, strong anti-explosive force, good impact resistance, no deformation of external pressure.
2. Working pressure is 0.25 MPa, 0.6 MPa, 1.0 MPa, 1.6 MPa, 2.5 mpa.

Working principle:

The limit rubber joint expands when pressed, and the force generated by the pressure is designated as the pressure thrust. If the pipe support and the anchor are not designed to absorb this force, the tie rod across the joint must be added. Rubber expansion joint with tie rod is designed to withstand full pressure thrust and the drawbar support is integrated into the flange (fixed ring) so there is no thrust on the corresponding flange. Rubber expansion joint with tie rod when pressed. by. It is recommended to prevent damage due to excessive pipe movement in most applications. Each rod contains a double nut at each end to prevent the expansion joint from exceeding the elongated and spherical washers, allowing lateral and some angular movement (only 2 rods only) ).

Application:

1.Widely used in chemical, construction, water supply, drainage, petroleum, light and heavy industry, refrigeration, sanitation, plumbing, fire, electricity and other basic projects.
2 Rubber expansion joint with tie rod for indoor installation.
3. Tie rod rubber joints are suitable for outdoor installation.
4. Rubber expansion joint with tie rod is suitable for embedded installation.

NOTES:

Flange is available with DIN Standard,ANSI Standard,JIS Standard,and BS Standard.
The size is available DN32- DN3000
Please sent us letter and drawing for customization if you have special requirements.
If this product is used for supplying water for high place, anti-pull-off device should be installed if the pipe has or fixed bracket is not as no fixed stay or fixed bracket or the force of fixed bracket is not large than axial force.

Flexible rubber joints shall not exceed the displacement limit during installation.
In the installation of bolts to be symmetrical, to gradually pressure and tighten, to prevent partial leakage.
When the rubber joint is laid flat, suspended, and vertically installed, the actual working axial displacement pressure of the rubber joint should be less than the supporting force of the pipeline, otherwise the anti-lifting device should be installed to prevent the work from being pulled.
The installation location of the rubber joint should be kept away from the heat source and ozone area. It is strictly forbidden to irradiate with strong radiation, expose to the sun and use the medium that does not meet the requirements of this product.
When the rubber joint is transported, loaded, unloaded or installed, it is strictly forbidden to sharpen the surface sealing surface.
When installing DN200mm or above, please use butterfly valve special flange or small diameter flange for mating flange, so as to avoid flange pull-out, misalignment, sealing surface fracturing and water leakage after installation.
