Greetings fellow engineers,
Some of you may be familiar with the problem low silicon (<0.1%) carbon steel presents in sulfidation services: unpredictable (and possibly much higher) uniform corrosion rates.
Fortunately, A-106 has a minimum Silicon spec of 0.10%, which eliminates the concern...
Fellows,
I am replacing an exchanger that has a carbon steel tubesheet and 1" 304 tubes. The shell side operates at 500degF. Besides service/corrosion concerns (we have those lined out), are there mechanical issues with the tube to tubesheet joint?
I feel the difference in thermal expansion...
Greetings fellow engineers,
I am supporting a project in which we will be adding a nozzle to an existing airfin heat exchanger designed to API 661.
API 661, para 9.2.1 states "All carbon steel..headers shall be subjected to post weld heat treatment".
I would like to understand the intent of...
