These are the most common sources of corrosion<\/strong> in the metallic compensators<\/strong> or metal expansion joints<\/strong>:<\/p>\n \u00a0<\/p>\n The oxidation at high temperatures<\/strong> is also a very common corrosion mechanism that occurs very frequently in exhaust pipes or pipings processing hot air.<\/p><\/blockquote>\n \u00a0<\/p>\n The material selection should be such that there is no possibility of corrosion or that the corrosion rate is not higher than 0.002 inches per year. The resistance against corrosion<\/strong> of the stainless steel<\/strong> rests on naturally occurring chromium rich oxide film formed slowly on the surface of the steel. Some stainless steel impurities as well as welding spatters can prevent or hinder the formation of this chromium oxide film, therefore, the remaining impurities must be removed by pickling, in order to get the maximum resistance against corrosion.<\/p>\n Regarding the presence of welding splashes, this is an issue that must be prevented in the workshop as well as during normal operation by protecting the bellows or by applying some anti-splash compound on its surface.<\/p>\n \u00a0<\/p>\n When designing a piping system<\/strong> integrating metal expansion joints or metallic compensators,<\/strong> particular care is required not only to the internal conditions but also to the external ones. In practice, numerous corrosion attacks<\/strong> can be significantly minimized with a well-planned study, which would help to get a proper design. The designer or engineer must foresee the situations in which the corrosive attack may occur, due to a poor design as well as to a wrong material selection. Given that corrosion can be a complex issue, we recommend you to seek advice from engineers that are highly-skilled in materials, as those making up the Quality Department<\/strong> in SACOME<\/strong>.<\/p>\n [\/et_pb_text][\/et_pb_column][\/et_pb_row][\/et_pb_section][et_pb_section bb_built=”1″ fullwidth=”off” specialty=”off” prev_background_color=”#000000″][et_pb_row][et_pb_column type=”4_4″][et_pb_blog _builder_version=”3.17.6″ posts_number=”3″ include_categories=”34″ show_author=”off” show_date=”off” show_pagination=”off” fullwidth=”off” use_overlay=”on” hover_overlay_color=”rgba(0,0,0,0.44)” header_level=”h3″ \/][\/et_pb_column][\/et_pb_row][\/et_pb_section]<\/p>\n","protected":false},"excerpt":{"rendered":" The service life of a metal expansion joint or metallic compensator can be drastically reduced due to corrosion issues.

The impact of the corrosion<\/strong> will depend on its type and on the conditions of each material, as well as on the original surface state.<\/p>\n
