An expansion joint of Hanwel is not only good in absorbing vibrations. It is also a flexible pipe element (expansion piece) in piping that can reduce stress and absorb thermal expansion. An expansion joint can also compensate ground settlement. Our expansion joints are resistant to both high-and low temperatures and are suitable for high pressures.
For any temperature, pressure or application we can offer you the best expansion joint. Our specialists will be happy to advise you to obtain the lowest possible investment.
Rubber expansion joints
Stenflex rubber expansion joints are very flexible, that is why a relatively large movement on a short installation length can be compensated. Rubber expansion joints are extremely suitable for absorbing vibrations. A rubber expansion joint is almost maintenance free and has a long lifetime.
Stainless steel expansion joints
The Welflex stainless steel expansion joints are made of high quality stainless steel (SS), designed with flanged or welded connections. The stainless steel expansion joints are designed and manufactured based on the design conditions and customer specification. This allows us to deliver any shape, size and configuration.
PTFE expansion joints
Welflex PTFE expansion joints are very flexible, that is why a relatively large movement on a short installation length can be compensated. PTFE expansion joints have an excellent chemical resistance. The pressure resistance of PTFE expansion joints decreases at higher temperatures.
Fabric expansion joints
The Bording fabric expansion joints are very flexible, that is why a relatively large movement on a short installation length can be compensated. Fabric bellows are only suitable for gaseous media such as flue gas and air. A fabric expansion joint is always custom made and the material composition is based on the temperature and medium composition.
Sometimes a movement cannot be compensated by means of expansion joints. For example, if the pressure is too high or because you need a smooth inside. In that case, Welflex swivel joints can be a solution.
Considerations when using expansion joints
When expansion joints are applied, there are a number of issues to be considered. When those point are taken into account then you will enjoy years of a properly functioning expansion joints and piping system.
