Hi Stainless Steel Experts,
Is it possible to vacuum anneal (bright anneal) 316L and duplex 2205 parts at the same time? The annealing temps are almost the same (1900F/1040C) for both alloys and parts' thickness is less than 0.6 inches. I know 316L parts can be bright annealed with no major...
We are considering duplex 2205 or super duplex for some parts of this line. I know MR0175 is not a guideline for corrosion control or other type of corrosion like pitting. I was following it for partial pressure calculations. I wasn't aware the 0.05 psi H2S limit only applies to carbon steels...
Hi Steve,
Thanks for all your helpful tips and hints. This is very useful information. I am following MR0175/ISO15156 and according to the standard you just need as little as 0.05 psi partial pressure to be considered sour. I also noted that ISO 15156-3 has more information regarding 316L...
Hi,
I need some guidance in this matter! I received a water analysis for a water injection line operating at 700 psi, 50C. I need to determine if the fluid is sour and if it is compatible with 316L. The water contains:
CO2 Gas Analysis 18.12(%)
H2S Gas Analysis 0.2211(%)
Total H2Saq @...
Hi Denlow60,
There will be some machining involved, so the final sizes of the tubes needed are:
OD(in) ID (in)
2.45 1.50
3.6 2.26
4.50 3.0
6.75 4.8
8.75 6.9
Anything slightly thicker/bigger will help.
Hi,
Hope someone can help me with this query. I need to find a en equivalent US grade to EN 10210-S355 J2H (1.0576), which is a structural non alloy steel good for relatively cold temperatures. I need seamless tubes not pipes. It is the low temperature application and sizes what is making it...
