Product Introduction
Double ball rubber joint is a kind of pipe joint with high elasticity, high air tightness,
medium resistance and weather resistance, which is composed of an
inner rubber layer, a reinforcing layer (multi-layer squeegee nylon
cord fabric) and a rubber pipe with an outer rubber layer.
These joints are designed to reduce vibration and noise, and to
compensate for thermal expansion and contraction caused by
temperature changes.
The double-ball design not only enhances flexibility, but also
greatly improves its pressure-bearing capacity and fatigue
resistance, ensuring the tightness, corrosion resistance and aging
resistance of the joint.
In addition, the metal skeleton of the double ball rubber joint is
mostly made of stainless steel or high-strength alloy steel, which
further improves the overall strength and stability, so that it can
evenly distribute the stress when subjected to high pressure, and
effectively avoid the risk of rupture caused by single-point
concentrated force.
The elastic properties of rubber can effectively absorb and slow
down pipeline vibrations, reduce noise pollution, and improve the
quality of the working environment.
Installation method
1. It is strictly forbidden to install beyond the displacement
limit.
2. The installation bolts should be symmetrical, and gradually
pressurized and tightened to prevent local leakage.
3. When the working pressure is above 1.6MPa, the installation bolt
should have an elastic pressure pad to prevent the bolt from
loosening during work.
4. When installed vertically, the two ends of the joint pipe should
be supported by vertical force, and anti-pull-off devices can be
adopted to prevent the work from being pulled off under pressure.
5. The installation part of the double sphere rubber joint should
be far away from the heat source and ozone area, and it is strictly
forbidden to expose to strong radiation rays and use media that do
not meet the requirements of this product.
