Good morning to all (Italian time).
I would like to talk about pitting corrosion in oil and gas applications.
Taking in consideration 316SS and a wet stream with an important amount of salinity (dissolved chlorides),
from my academic studies I know that without oxigen, and the relevant cathodic...
I'm selecting a material for a pump (impeller and shaft) in Sour Service as per NACE MR 0175.
My first choice is 17-4 PH above all becouse in the first period the service is not sour and for the future 200 ppm is indicated (very low).
My doubt is, with reference of section A.8 (Precipitation...
Hi all.
I don't if this is the right forum, but i'll try.
Could you please suggest me some books, articles of handbooks, or something like this concerning pipe manufacturing: LSAW (JCOE,UOE, 3roll bending),HSAW, ERW, etc... that involve all the metallurgic, processes of production aspects etc...
I have problems with the presence of some points of general corrosion in the Air-Intake conduit of a gas turbine.
The material is 304.
Is there an international standard or norm or something like this that regulate the presence of this points of general corrosion? i mean something like a...
My Client gave me a datasheet of a ball valve, in which an electroless nickel plating surface treatment (min. thk. 50 microns)is required for a standard (non corrosive) service.
I really don't understand the advantages of this choice versus the cost of this treatment (i have 16" valves!!).
Thanks
I'm looking for a coating system for an internal epoxy lining of some carbon steel vessels.
The stream is wet natural gas with the presenze of carbon dioxide with a partial pressure under 11 psia.
Thanks
Hi all.
I have to design some separators with ASME VIII Div. 1. One of these is 20" ID.
My Owner wants the possibility to have access to the internals (vane packs) for maintenance. So i need a manhole at least of 18-20 inches and of course it's impossible for a vessel with 20" ID.
The question...
