Pipeline material selection
Thread Content
The composition of the bottom condensate from the demister tank of the acidic water stripping unit is relatively complex, with high levels of hydrogen sulfide and ammonia. Pipeline transportation may involve strong acid corrosion and ammonium salt crystallization. What material should be used for the pipeline under these operating conditions?
One could consider choosing steel-lined fluoroplastic. It has good corrosion resistance.
Steel weighing has temperature and pressure limitations. If the temperature is high, 316L may not be suitable either; consider 2205 duplex steel or titanium alloys.
Agree to use 2205 duplex stainless steel or titanium tubes!
316 is not suitable; it’s better to use carbon steel rather than 316. If cost is a concern, carbon steel can be used without any problems for a few years. I estimate that 316 will start to have issues after at most two years
Stainless steel 304 and 316 both work, right?
The carbon steel at the site is suffering from severe corrosion, so the material needs to be replaced.
What material are your equipment made of, and is there any corrosion?
When the pipeline pressure is less than 5 bar, glass pipes can be used. Glass is not as fragile as one might think. If a lining is used, Halar is a better choice; it is more durable and offers greater reliability when crystallized, although it is generally more expensive than glass
