Expansion Joints & Hoses

Expansion Joints & Hoses are relevant for many industries, i.e. chemical, petrochem, power generations, food & beverage, PtX, marine & offshore, onshore and not least also HVAC and engines. 

They are installed where thermal processes occur, which create stress, vibrations, noise, movements, and offsets in the piping systems or to connect from one vessel unit/process to another.

Our Expansion Joints & Hoses are designed and manufactured according to the latest norms & standards and the materials used are mainly harmonized.

Read more about the Expansion Joints & Hoses available from KLINGER Denmark:

Metal Expansion Joints
are most common in either circular or rectangular shapes. The bellow elements are most common in stainless steel (SS) quality and for the Lens type, also available in carbon steel (CS) quality.

Metal expansion joints are highly specialized and engineered products and are to be installed where thermal processes occur as described above. 

Fabric Expansion Joints 
are most common in either circular or rectangular shapes. Fabric Expansion Joints are different from Metal and Rubber Expansion Joints as they are used when pressure is low and temperature high, and they are much more flexible.

Fabric Expansion Joints are “make to order” and not standard of the shelf, unless it’s tailor made for a specific product range for a specific customer. They can be highly engineered products for special industries and are installed where thermal processes occur.

Rubber Expansion Joints
consist of two main groups: standard and special molded. The bellow elements are most common in EPDM & NBR materials, but other materials as well as a combination of these are also available.

Similarly to Metal Expansion Joints, Rubber Expansion Joints can be standard products, but can also be highly specialized/engineered products. The main differences from the Metal and Rubber Expansion Joints are the temperature and pressure limits, but for corrosive applications at lower temperature, our Rubber Expansion Joints are perfect.

PTFE Expansion Joints 
are available in circular shapes and certified for up to 100,000 cycles. They are built similarly to Metal and Rubber types but are for mid-range pressures and with high corrosion resistance. 

The bellow is flared over the flanges, which eliminates the need for separate gaskets. They offer low spring rates to protect sensitive equipment.

Hoses
come in a wide range, mostly with metal body and outer braiding, but also with PTFE body with reinforcement or with lining with 100% PTFE/other materials as customized. 

The hoses are highly specialized products for multiple purposes and similarly to Expansion Joints, they can be installed where thermal processes occur.
