For the well stream composition.We are considering the line pipe material-API 5L Gr X65, as per NACE MR 0175.
One has suggested to select Carbon steel with Corr.Allowance of 1.6mm is this selection Ok with this corr.allow??
Considering Line pipe API 5LGrX65 is it also suitable material and...
Hi
Need your feedback on MOC.
Currently we are using FRP epoxy pipes to transfer Titanium dioxide pigment from treatment tank to other equipment. we want to shift MOC of piping from FRP to CPVC?? Can you comment on new suggested MOC.The tank mainly contain TiO2 pigment and some fraction of...

Hello All
I did ask same question before but this time I will be very specific to MOC Inquiry.
As per our current setup of MOC, we want to use Glass Reinforced FRP Epoxy, CPVC for piping and C.S (rubber/brick lined) for Tanks/agitators. Could some one be sure that these Materials resist...
Hello
could you please provide comments on if C.S ASTM A-106 Gr-B be used for 20%HCL??? we are using same material for fresh/spent H2S04 as per bechtel piping specs recommendation. I found through bechtel piping specs that for HCL, Glass reinforced FRP Epoxy resin and CPVC are recommended...
Hello All
I require some feedback from you guys. very soon we are going to shift from H2S04 to 20%HCL (Dilute) usuage in one of our equipment for making end product.I have two concerns regarding Material of construction, one is for HCL itself and CL (chloride ions). As chloride itself might...
The service temp for operating would be around 200-250C in recycle gas blowers. what be the strength of C-22 at this temp??? as comparing with SS-410.
Thanks
Norm
Good Day All
One question?? from mechanical strength point of view which alloy shows more promising strength that is If I compare C-22 with SS-410 and SS-403. I have proposed in using C-22 alloy as MOC for Impellors in Recycle Gas blowers. As C-22 is more chlorine (WET/DRY)Corrosion resistant as...
Good Day All
I need some info from you folks.
We are currently using Supertherm Alloy in our Oxygen pre-heater (furnace),At our current operating temp close to 950C. we get sudden elongation due to high oxidation rate. I had a metallurgical analysis and found that under high temp, oxidation is...
Guys
Can you suggest any other alloys(Good Thermal conductivity)other than Nickel-200 for (AlCl3+Ticl4)corrosive media.in other words alloys which can resist some how pitting.
Thanks

One Inquiry.
There are 5 vessel-sand separators we use in one of our production units.
We are facing frequent change overs on the down leg spools(Angled straight pipes with 45degree or 90degree) made from SS-316 due to flow of solid pigment (TiO2), sand scouring and small traces of gases. The...
There are 4 agitator tanks in which we add different type of solutions to give a required pigment/slurry Grade based upon PH values. The max. Temp in agitator can get close to 85-C(centigrade).
The input chemicals/solutions in a tank are:
-Fresh & Spent Sulphuric Acid
-Zirconyl orthosulphate...
Good Day All
I would like to draw your attention to one problem dealing with pitting corrosion in Nickel tube bundle, mostly in the ends of U-tube, of heat exchangers. We are mainly using nickel tubing as it has a Good heat transfer property which off course delivers a Good evaporation of the...
