Jim and Gerhardl Thank you very much for the valuable knowledge shared. Regards kudroli

Hello: Is there any industry guidence for the maximum number of turns (from fully open to close position) allowed in case of gear operated valves. In one of my previous project, vendor had offered valves with 750 turns (of course it was 80" valve). Advice on this issue is higghly appreciated...

Hello gr2vessels: Thanks for your time and advice, Finger sizes are 48" & design pressure is 150 Bar. Factory assembling and transportation of Slug catcher may not be feasible due the transportation related problem (Involvement of field welds may be immanent) For the upstream and down...

gr2vessels: As per preliminary depressurization study the depressurization temperature is -80 deg C at 6 barg (With 10 degree Process margin on temperature and no margin on prssure)

Gas being handled is sweet one (Almost no H2S). Hence application of NACE does not arise. Please note, Company requirement is Finger type slug catcher. Selection of ASME Section VIII or any other pressure vessel code for slug catcher is complicating the suitable pipe material/code for the...

Friends: Can we apply code ASME Section VIII Div 2. I have been told that, we have the thickness advantage with Div 2 compared with Div 1. Regards

Further to above query, If I acn apply ISO 13623 code for the design of Slug catcher, could you please advise the suitable carbon steel material that can be subject to -80 Deg C and provide required notch toughness (27 J average/20 J individual with SMYS less than 360 MPa or 40J average/30 J...

Dear friends: I have a situation where slug catcher is subject to the depressurization temperature of -80 Deg C at 6 bar(With ambient temperature considered as -39 Deg C). Whether some has experience in design of slug catcher at such a low temperatue? What design code and material to be used...

For Cryogenic valves clinet has a requirement for the "Collar rings" at the extended bonnets. I do not know how/where this collar ring is connected with the extended bonnet. Can some one help on this?

I am looking for the suitable material for Superheated steam (110 Barg @550 Deg C). After analyzing between P22 & P91, it is observed that P91 is best suited in terms of Rating and wall thickness point of view. However the plant been built in a cold country, where minimum design temparature is...
