China Double Sphere Rubber Expansion Joint Suppliers

A Double Sphere Rubber Expansion Joint is an advanced Rubber Expansion Joint with two interconnected spherical rubber bodies, offering enhanced flexibility for pipeline systems. It utilizes rubber’s elastic deformation to compensate for larger axial, lateral, and angular displacements caused by thermal expansion, pressure fluctuations, or mechanical vibration, effectively reducing stress on pipes, pumps, and valves.

Crafted from high-grade elastomers like EPDM, natural rubber, or nitrile, reinforced with fabric or metal layers, it delivers excellent corrosion resistance and durability. Compatible with media such as water, chemicals, and oils, it’s widely used in HVAC, water treatment, and industrial pipelines. Its Flange or threaded ends simplify installation, with a Flange Adaptor ensuring compatibility with diverse flange specifications.

In system integration, it works synergistically with other components: a Bellow Expansion Joint handles extreme thermal displacements, while this double sphere joint absorbs vibrations. A Flexible Metal Hose adds routing flexibility nearby. A Dismantling Joint eases maintenance by enabling quick disassembly. Paired with a Duckbill Check Valve, it enhances backflow prevention.

Key advantages include superior displacement capacity, effective vibration/noise reduction, and easy installation. Its compact dual-sphere design saves space while handling greater movement than single-sphere variants. By maintaining tight seals during operation, it ensures reliable, efficient pipeline performance, making it indispensable in complex fluid handling networks.

Double Sphere Rubber Expansion Joint

The ‌Double Sphere Rubber Expansion Joint‌ is a pipe connector consisting of two spherical rubber parts, mainly used to absorb vibration, displacement and noise in the pipeline. It is made of high-quality rubber material, has extremely strong elasticity and pressure resistance, and can maintain stable performance in harsh environments such as high pressure and high temperature. The double sphere rubber expansion joint is composed of a rubber tube composited with an inner rubber layer, a reinforcement layer (multi-layer scraped nylon cord fabric) and an outer rubber layer, and is usually combined with a metal flange or parallel joint loose sleeve. Its double ball design enables it to perform well when subjected to lateral, axial and angular displacement, effectively reducing the stress on the pipeline, thereby extending the service life of the pipeline.

Product Detail

The double sphere rubber expansion joint is composed of a rubber tube composited with an inner rubber layer, a reinforcement layer (multi-layer scraped nylon cord fabric) and an outer rubber layer. This structure makes the double sphere rubber expansion joint have high elasticity, high air tightness, medium resistance and weather resistance.

The inner rubber layer is in direct contact with the medium, such as natural rubber, styrene-butadiene rubber, butyl rubber, nitrile rubber, EPDM rubber, chloroprene rubber, silicone rubber, fluororubber, etc. These materials have the functions of heat resistance, acid resistance, alkali resistance, corrosion resistance, wear resistance and oil resistance.

The reinforcement layer is generally a multi-layer scraped nylon cord fabric, which provides the strength and stability of the joint.

The outer rubber layer mainly plays a protective role to prevent the joint from being damaged by the external environment.

WHAT A CLIENT SAY?

Customers found during use that this joint can effectively prevent medium leakage and ensure the safe and stable operation of the pipeline system. At the same time, its sealing performance is also reflected in the isolation of the external environment, which can effectively prevent the intrusion of external impurities and moisture, and extend the service life of the pipeline. The convenience of installation has greatly helped the smooth progress of the project, especially in the case of tight construction period, it can greatly shorten the construction period. The double sphere rubber expansion joint adopts a unique double-layer sealing structure to achieve good watertightness and airtightness. Customers found that this joint can effectively prevent medium leakage, and the sealing performance can effectively prevent external impurities and moisture from invading, extending the service life of the pipeline.

FAQ

Important things you should know

In what cases does the rubber flexible joint need to be installed with a limit device?

When the diameter of the pipe is larger than DN200, when it is installed in the air, the pipe vibrates or has slopes or turns, or the pipe material is hard.

Why do you need to install a limit device on the rubber joint?

The purpose of adding a limit device is to ensure the stability and reliability of the rubber flexible joint during use, prevent it from falling off or deforming under the action of external force, and thus ensure the normal operation and safety of the pipeline.

What is the role of rubber flexible joints in pipeline systems?

Rubber flexible joints play an important role in connection and compensation in pipeline systems, especially in places where vibration absorption, thermal expansion and contraction compensation, or shock absorption are required.

What should be paid attention to when installing rubber joints?

During installation, attention should be paid to the sealing performance of the flange and rubber flexible joint to ensure that no leakage occurs.
