thank you so much unclesyd farhad

Please some body tells me ,it is necessary a spiral wound gasket have a inner ring. Our piping design pressure is 54 Bar and temp is 200 C. Thank you Farhad

Hi thank you very much plymouth tube

Hi Please tell me, We have salty water for our fire fighting network. The pressure is 130 psi and temperature is 30C. we have to kind of gate valve material body .one is Ductile iron and another is Cast Iron and both of them have epoxy coated (inside and outside) .just I want to know...

thank you Mattc1234 Actually My question is ,can we use ASTM105+stellite disc in globe valve instead of %13 chrome steel +stellite disc because fluid (gas or liquid ) touch to the surface of the disc (stellite surface) farhad

Hi Every body can tell me if globe valve disc and seat are 13% chrome steel. It can be stellite or it doesn’t need stellite .the service of valve for sweet gas. Thank you farhad

Sorry I did mistake. Actually in clamp catalogue write it down 30 ksi and I wrote by mistake kpi .so this is stress unit, and just tell me please how can I calculate the clamp can bear 43000 N forces when pipe is going up. Already we did stress analysis and with this force we are not going to...

Dear friend Thank you for your answer .this pipe is going to input of a compressor .we don’t like flange of the compressor get over stress .yes you are right .we can change piping arrangement to limit or reduce force, but it is not time to do this change for us . Would you please tell me...

Hi: Every body We have a 24 inch pipe, according to our stress analysis it coming up from its support at a point with a force 46303 N during operation .our contractor suggested to put a clamp that permissible force is 30Kips to keep it down . Can you tell me . is this right?.Thank for your...

thank for answering to my question i am going to use following Equation for allowable load on the flang of compressoer according to NEMA-23 Fx=50Dc Fy=125 Dc Fz=100 Dc Mx= 250Dc My= 125Dc Mz=125Dc Dc= (18+equivalent dimeter)/3 Am i right ? best regard farhad

hi ;DSB123 thank you for you answer . Really i am right. They wrote like this in the meeting with my company .I wasnt involve that time.so please tell me if you know a bout 10x NEMA . best regard farhad

Hi I recently involved with a compressor it has 16’’ flange at output. I am going to do stress analyze the pipe is connecting to this compressor. The vender’s catalogue mentioned that this compressor’s flange can outstand 10x NEMA forces . I would be appreciated if some body tell me what mean...

I will appreciate some body answer my question .i have stainless steel valve with body AISI 316SS.they use A193 B7 and A194 2H for bolt and nut in this valve .i think they are wrong. they should to use A193 B8M and A194 8M. Am I righ best regard farhad

Dear Edward Please tell me how can I use allowable load tables (in API-610 ) in stress analyses .when a pipe connect to the pump. best regard farhad

Actually, I am going to calculate pipe stress analyze for a pipe that connect to a pump so I start first node with flange so the program asked me following question for flange 1-flange type 2-flange weight 3-gasket diameter 4-allowable pressure. I don’t know what does the programs...

Is any body Know how I can find external nozzle loads and moments for nozzle’s pump . I need those for stress analysing program. I found those in in API610 but there are in force unit(pound) I need stress(F/A)psi . thanks

i have flange with material ASTM A694-F60. i am going to use for temperature 400 F and pressure 54bar . i couldnt find this material in ASME B 16.5 - can some body help me thank farhad

Thank you for your answer. But I looking for standard ,that tell me when should I use schedule higher .
