CASE STORY:
HELPING A CLIENT HAVING
A LEAKING SCRUBBER EXPANSION JOINT

Problem

A client approached Belman as they were having a leaking Expansion Joint in their scrubber system. The bellows were made from 254 SMO, which along with other stainless steel materials is often used for scrubber application. This material is a good choice in most cases. However, in this situation, the media was more corrosive than expected and therefore resulted in leakages on the bellow.

Why does this problem happen?

Belman see more and more often that some scrubbers are having operating data and a media composition that is more corrosive than others. This sets higher demands for the components (such as Expansion Joints) and the materials they are made of. It is not only the Expansion joints having this issue, but due to the wall thickness it will be the first component showing the corrosion problem. Expansion Joints are made from several layers of thin plate, in order to make them flexible and able move and absorb movements in the scrubber system. The flanges of the Expansion Joints are not at risk as the flanges are loose flanges and constructed in a special way, so that they are not in touch with the media. Flanges are therefore not made from 254 SMO or likewise stainless steel materials. Furthermore, the scrubber and piping itself is not a critical issue, as these are made from thicker walled steel.

 

Solution

In this case Belman analyzed the client’s problem and proposed the client a more durable solution in order to prevent future premature leakage on the Expansion Joints in their scrubber system. Belman suggested the client an Expansion Joint made from higher alloyed steel – in this case a bellow made from Alloy 59, which is resistant to the very corrosive media in their scrubber system. A higher alloyed material was therefore what this client needed in this situation for safe and reliable operation.
