Electro Slag Weld for Internal cladding of Amine Regeneration Columns
Electro Slag Weld for Internal cladding of Amine Regeneration Columns
(OP)
Hi to all,
I'm preparing a Data Sheet for an Amine Regeneration Column. As i have studied and known the Amine process is very corrosive principally for two effects :
1- CO2 Corrosion;
2- Second Amine corrosion due to the product formed with CO2 and H2S (if present - in my case i have only CO2);
for this i have selected an AISI 316 Cladding on a low temp coloumn in order to avoid possible cracks in the Carbon steel welds. I have seen that to clad this coloumns it is used the ESW (electro slag weld) someone can show me how this technic function and if is possible use this technic for cladding of AISI materials? There are some other cladding Technics?
Thanks to all, with my regards Vincenzo Saviello.

I would recommend you visit the web site below search for information on cladding and contact the esab folks directly;

Your selection of cladding is more for control of amine corrosion (general metal loss and pitting) and CO2 corrosion (again general metal loss and pitting) rather than cracking. PWHT would control amine stress corrosion cracking in carbon steel but not amine corrosion in the lower liquid region or CO2 corrosion in the condensation region at the top of the column.
As to learning about the welding process, those wonderful Google people come to the rescue as always:
