TANIQ Rubber Expansion Joints


A rubber expansion joint is a mechanically engineered rubber product that is inserted into rigid piping systems to absorb movements. This type of joint also helps improve thermal stability and compensate for misalignment. TANIQ has developed a new optimized design for rubber expansion joints based on lightweight engineering principles and finite element analysis. During the manufacturing process, materials are placed in the optimum positions using automated winding equipment. This process results in a significant cost reduction and an increase in quality.

Rubber expansion joints are reinforced using a prefabricated cord fabric, such as nylon tire cord fabric. These reinforcement cords are woven into a predetermined pattern and positioned onto a mandrel. The rubber compound is then applied onto the cords. After this process, the reinforced rubber sheets are wrapped around a mandrel or green form.


Flexicraft rubber expansion joints are made from a wide variety of materials. These joints are made from natural or synthetic elastomers, fabrics, or metallic reinforcements. They are designed to give piping systems a flexible, stress-free connection. Their flexible design is ideal for piping systems that are subjected to mechanical and thermal vibration.

They are the most versatile of all rubber expansion joints. They can be used for pipes of any diameter and can be manufactured with virtually any elastomer. Flexicraft rubber expansion joints are available in single or double arch models, and they can also be customized to suit non-standard designs and elastomer options. Many models are also available with flanges and control units.


The Senior Flexonics Group designs expansion joint systems and bellows for use in gas, waste heat recovery, process heat utilisation, and HVAC applications. Its engineering capabilities include non-linear, linear, and analytic calculation methods. Its in-house test facilities and expertise enable it to optimise its designs for long-term reliability.

Using a hydraulic forming process, Senior Flexonics offers a variety of corrugation profiles, wall thicknesses, and braiding layouts. These flexible and durable components are able to withstand the toughest of operating conditions, making them ideal for critical applications. They also meet DIN EN ISO 9001, ISO/TS16949, and ISO 14001 standards.


A rubber expansion joint is a flexible pipe fitting that connects two ends of a piping system. They can be made of either natural or synthetic rubber. A steel flange engages the rubber expansion joint flexible end of the joint and allows easy rotation for speedy installation. These flexible piping connectors are ideal for isolating smaller diameter piping from vibrating mechanical equipment.

There are many advantages to using a rubber expansion joint. It is cost-effective, maintenance-free and durable. There are many different types of rubber expansion joints.

General Rubber

A General rubber expansion joint is a mechanical connector that connects piping systems. It must be able to withstand pressure and temperature variations. It must also meet certain requirements for design, materials and performance data. Moreover, it must be stamped by a licensed engineer who is employed by the manufacturer. A good manufacturer should also be willing to offer onsite services and training seminars.

General Rubber expansion joints offer a variety of benefits. They provide system flexibility by absorbing pressure thrust forces, and they can absorb directional movement in piping systems. They also reduce vibration and noise, and they compensate for piping misalignments. They also allow for access to piping and other equipment. In addition, General Rubber’s Maxi-Joint(r) wide arch expansion joint provides superior movement capability compared to metallic joints.
