Hello, I have developed a software to solve steady state gas networks , it's still under test. I will be delightful to you if you helped me by testing it and giving me your feedback, thank...

Hello Everybody Could anyone tell me please if it allowed in piping arrangement for natural gas to use some diameter for a portion of piping arrangement then use a smaller diameter for a small pipe segment or valve then back again to the diameter that I started with. for example I have an...

Hi all, I'm asking if there is a difference between design procedure for piping system which may found inside some industrial facility as oil refinery or petrochemical facility and design procedure of natural gas transmission pipelines facilities as metering stations. note that, I don't asking...

hi all, I'm asking about API issues , especially in piping work as API 5D, API 6D, API 598 and so on. are these issues can be considered codes or standards or some issues are codes and other ones are standards ?? thank you in advance

hi all until two days ago I was believing that wall thickness calculations for piping of compressor, metering and pressure reduction stations of gas transmission pipelines follow ASME B31.3 code. but when I started to skim the code; I found it states that piping of compressor stations and...

I want to know , is that useful to read the code or standard as ASME B31.3 or ASME B31.8 from cover to cover as I read a book ? my idea it will not be useful, but I still need to discover the code, knowing what chapters and sections talking about. I know there are a courses introduced for...

Hello all, referring to point of gas pipeline operation cycles , is there any code managing or talking about max number of pressurizing and depressurizing cycles to avoid fatigue effects on pipeline material ?? thank you in advance

Hello all, I have a strange case, please help me with: I received a new equipment (gas turbine meter) with flanges connection, but the holes of the flanges are threaded ?? and the flange welded to the pipe is a normal ansi flange (b16.5), so when installing the turbine-meter, the bolt suppose...

Hello, I would like to ask if it is possible to use plug valve in manual throttling service and keep it partially close for a long times like 2 or 3 months in gas service ?? if not, what is the suitable type of valves can do that thank you in advance

Hello , I would like to ask about NDT and pressure tests for pipes in mill, do these tests executed for all pipes lot or for sample (as destructive tests) thank you in advance

Hello, i would like to know that does asme b31.3 wall thickness equation can be valid to calculate tubing wall thickness (as heat exchanger tubing) thank you in advance

Hello, I would like to ask about mill tests to be conducted on pipes as (charpy impact, guided bend, UT & RT, hydro static pressure test) , is every material grade has its own types of tests or these tests shall be conducted on every pipes with any material grades? for example: tests to be...

Hello all, Is there any reference giving me an approximate values for valves cg or cv when working in gasaes (scfh / psi) according to valve type (ball, plug, globe,..) and valve flanges NPS. thank you

Hello, I was working on vacuum distillation tower design with following data diameter : 6.8 m Length : 20 m I calculated the whole suction load needed as 25900 m3/hr @ 5 minutes needed to attain the vacuum. and I select that I need 10 ejectors with size of every one is about 10 inches...

Hello, I need to make cost evaluation for a new distillation unit, so I need to estimate approximately the running cost of heat ex-changers & pumps as a percent of fixed cost, can any one help me even with rough values ?? thank you in advance

Hello, I'm working on new distillation unit heat ex-changers design, at this unit, the products get cooled after getting out of the tower by exchanging with treated water, the water will be converted into steam, which can be used in the plant, the question is, is that will make any difference...

Hello all I need a simple procedure or a simple steps to design or selection the following equipments - shell and tube heat ex-changer - furnace which heating crude before entering a distillation unit in oil refinery my work career actually away from this field, but this task needed for...

hi, I want to ask about API piping inspector certificate (API 570) and API pipeline inspection certficate ( API 1169), what is the difference between them, and can I take them online? thank you

kindly, i want to know what is BWG in tubing and what is designation standards for tubing thank you

Dear friends, I heard from some engineers, that, conducting hyd. static test on pipeline; must be before installing secion valve rooms,especially for natural gas and crude oil pipelines, to keep valves safely from dust and impurities. is that true or what thank you in advance.
