Technical clarification
We help narrow down the right solution type before further technical dialogue.
The assessment starts with medium, temperature, pressure, movements and geometry — making it easier to identify which expansion joint type is typically the best fit.
STEEL
Used where high temperature, pressure and controlled movements place clear demands on the construction.
RUBBER
A practical solution where vibration, noise and smaller movement deviations must be handled between equipment and piping.
PTFE
Relevant in systems with corrosive media or chemical conditions that limit the use of other materials.
FABRIC
Relevant in flue gas, exhaust and duct systems where low weight and large movements are an important part of the solution.
Overview
The four groups cover different needs in industry and process plants. This is a short category guide that makes it easier to orient yourself before further technical clarification.
Typically considered in piping systems where reliability, defined movements and robust material properties are central.
Relevant around pumps, units and water systems where a flexible transition can relieve the installation.
Used in solutions where chemical resistance and material compatibility outweigh a more standard construction.
Often the right direction in flue gas, exhaust and duct systems with low weight, demanding transitions and high flexibility.
Assessment
A good choice rarely starts with product type alone. In practice, it is the interplay between medium, temperature, pressure, movements and available space in the installation that determines which solution fits best. Geometry, installation dimensions and transitions between components often influence the solution direction earlier than expected.
Chemical influence, cleanliness and process conditions affect material choice and construction.
Continuous operating temperature and peaks set clear limits for which solution is relevant.
Pressure level and tightness requirements should be assessed early to avoid the wrong solution direction.
Axial, lateral and combined movements must be evaluated from actual operation, not only nominal data.
Next step
For a faster initial assessment, it helps to send a few key data points early. This makes it easier to narrow down the right solution type and move more efficiently into the technical dialogue.
