Expansion joints

Our customized expansion joints can meet every requirement and protect your process – Frenzelit quality pays for itself.

Expansion joints withstand a lot: Dynamic movements, stresses, high temperatures or aggressive media

Expansion joints are an indispensable part of industrial engineering: They are flexible components that compensate for axial, lateral or angular movements in canals, pipelines and joints. They are chemically resistant and stable when subject to over or negative pressure. And they keep the system sealed tight against outside influences. We have realized countless projects, so we understand that every system presents new challenges – from the often gigantic dimensions of many plants to the highest possible tightness standards in hydrogen applications, for instance.

We work with our customers to find the right solution for their needs and implement these solutions all from a single source – offering a complete portfolio of services if desired. Frenzelit is a full-service provider: We have comprehensive materials and coatings know-how, we produce our special fabrics ourselves and we have an experienced team of experts for consulting, design and installation. In-house at our headquarters or worldwide at your site.

 

We can offer you expansion joints for every specification:

EXPANSION JOINTS: Our product range

Fabric and non-metallic expansion joints

Expansion joint engineering for industrial plant engineering: Size, material, number of textile layers, etc. are customized for every project.

Rubber expansion joints

For small diameters in standardized lengths and sizes or according to customer requirements.

Elastomer expansion joints

Made of highly flexible materials – ideally suited for use with wet media or where condensation is present.

Metal expansion joints

Individually produced, round, square, in almost any dimension – for high tightness requirements with media under very high pressures.

Expansion joints made of PTFE composite materials

High media resistance, tear resistant and flexible: Innovative expansion joint materials made by Frenzelit extend the traditional advantages of PTFE.

APPLICATION AREAS

Reliability in all industries and environments

Plant engineering customers across all industries rely on Frenzelit expansion joints. Examples can be found in power plants, in the steel, iron and aluminum industry, as well as in the chemical, food or drinking water industry. Our expansion joints are also underway in ships, commercial vehicles and railway vehicles.

QUALITY

Our product quality, longevity and service are impressive. An expansion joint should be a product that you install and then “forget about” for the next eight to ten years because it simply functions perfectly.

System availability translates into cash savings – Frenzelit helps rapidly in an emergency

Damage to expansion joints can shut down entire processes and be very costly. This is why Frenzelit reacts extremely rapidly. Our aim is to carry out an assessment within 24 hours at any site around the world, initiate repair measures and, where necessary, order the production of a new expansion joint. Production takes anywhere from a few hours to approximately two days. However, it would be better to use our expertise and our customer service well before this happens: During the planning phase of the system or when preparing for an inspection or a retrofit.

CUSTOMER AND INSTALLATION SERVICES

Everything from a single source, from project planning to commissioning

Our engineers, material specialists and technicians will find the best expansion joint solution together with you. An experienced, certified installation team is also at your disposal for full service installation, if required. Worldwide!
