The liangda rubber expansion joints are designed for piping systems to absorb pipe movements, relieve stress, reduce system noise/vibration, compensate for misalignment/offset and to protect rotating mechanical equipment against start-up surge forces.


Because of rubber has superior capability in resistance of acid, alkali, oil, and electrolytic, rubber expansion joint has become one of the alternatives of stainless steel and been successfully installed in tough demanding applications such as: chemical/petrochemical, marine, power generation, pulp/paper, steel mills and water/wastewater treatment.


The single sphere rubber joint is a single sphere design with less length, the supply range is from 25mm to 3000mm, and design pressure can be 1.0mpa/1.6mpa/2.5mpa, which is always used where low cost or space limitation control.



Rubber expansion joints features and benefits:
1, versatile hand-built construction. Made in china
2, absorbs directional movement
3, absorbs vibration, noise and shock
4, compensates for misalignment
5, wide flowing arch design
6, virtually eliminates sediment buildup
7, economical fully molded construction
8, high vacuum rating (up to 30" hg) can be supplied for certain sizes
9, special grooved flange ring design, prevent rubber end pulling out
10, solid galvanized steel floating flanges speed the installation time
11, high tensile aircraft cable is embedded in the raised face rubber ends to prevent pull out and avoids the sharp cutting edge of solid steel rings
12, no gaskets required; integrally rubber flanged design, no gaskets required, din pn10/16 drilling standard, other flange drilling available, including ansi 150lb/300 lb, bs, and jis.





We pack rubber expansion joints with neylon bags, wooden box, and according to your requirement.

1, Product Information:
Rubber expansion joints are flexible connectors fabricated of nature rubber or synthetic elastomers, steel ring and fabrics, and when necessary, metallic reinforcements provide stress relief in piping systems due to thermal and mechanical vibration and/or movements. ZHW® Rubber Expansion Joints provide relief from stresses caused by thermal expansion and contraction in pipelines. Movement is always experienced in piping systems due to varying ambient temperatures, differences in temperature of materials handled, and differences in composition. Expansion joints absorb this movement and eliminate the danger of buckling or pulling apart with the high replacement costs that would result.

2, Product Advantages:
Length of product customization
Tough quality and Widely Service
Absorption of Vibration, Noise and Shock
Wide Range of Flange Materials Available
Reduced Turbulence or Material Entrapment
Compensation for Misalignment

3, Product Applications:
It is extremely suitable for places where there are complex geologic conditions, large sedimentation range and pipes are easy to be damaged due to frequent alternation between heat and coldness in pipes. The elastic slide transfer and deformation of rubber and the heat dispersion of mechanical force may well prevent the physical damages from the displacement of pumps, valves and pipes. As a poor conductor, it is a harmless to reduce the vibration and noise transmission. The product is designed with smooth inner walls, after testing, it is proved to have no any influence on the flow speed and flux of medium, and keeps stainless for ever, accordingly it will be free of maintenance in operation.
