Metal Expansion Joints Technical Documentation
The service life of a metal expansion joint or metallic compensator can be drastically reduced due to corrosion issues. The design and operation conditions can influence meaningfully, in such a way that the bellows may be affected by corrosion issues whilst the surrounding pipes and supports may not, even though they are made of similar materials.
Design, manufacturing and test procedures are a key factor for metal expansion joints manufacturers. In this technical article we explain briefly how are the most important factor to take into account.
Our know-how designing and manufacturing metal expansion joints and metallic compensators since 1978, has shown us that certain breakdowns rest most of the time with the same mistakes or incidences, such as those set out in the following sections.
