Hi currently, I am in process for designing mechanical components for shiplift and transfer system operation. And, the standard itself (which is code for lifting appliance in a marine environment by LLoyd' Register) state that we should analyze seismic event. What I want to know, is this enough...

Well, thank you for the explanation. The issue is I worry that if fluid's velocity is too fast (when entering Pressure vessel) it could damage the pressure vessel. What I want to find is the rule of thumb or formula to determine the limit of fluid's velocity. For instance, in API 14E (I think)...

Actually in Liquid phase

Hi, currently I am designing pipeline, piping and pressure vessel system. I want to know maximum limit fluid's velocity input to pressure vessel. Is there any standard/code/book that I can refer to?

Hi, currently I am estimating cost of constructing and installation of LPG filling station. And, I want to know the cost/price for doing pneumatic test in LPG piping system and hydrostatic test in fire fighting system. Is there anyone that can provide me the estimation (in US dollar) regarding...

Thank you guys for answering my question, i really apreciate it

Hi, i'am currently designing oil tank and now I'm in the detailing stage regarding the drainage channel, in NFPA 30 They stated that : 22.11.2.6 Each diked area containing two or more tanks shall be subdivided, preferably by drainage channels .... 22.11.2.6.1 The drainage channels or...

Hello, I'm currently designing a bolted tank based on API 12B. is there any way to test this tank (such as hydrostatic test)? it doesn't seem to be described in detail by API 12B. Can I adopt the way the API 650 tank does?

Hello, I'm currently designing a rectangular tank with atmospheric design pressure. is there any way to test this tank other than those mentioned by UL142 ??? Given that the document says that the minimum pressure for the hydrostatic test is 30 psi. It looks like the design criteria for the...

thank you all, I really appreciate it

Currently, I am reviewing designs that are suitable for temporary/mobile tanks in the oil and gas sector. Therefore, I may ask, is the knockdown tank design suitable for storing crude oil? if there is an example, what standard should I refer to?Crude oil, Knockdown, Tank

How can we predict/determine the corrosion allowance on pipeline? at the time of initial pipe designCorrosion, Pipeline, Allowance

Thank you for the recommendation, right now i'm doing final project about HDD for steel pipe, i'm just curious about this information, if for case plain open trench or crossing river (the location close to road btw) is it still valid to use API 1102 or is there another code ? For information...

How do I calculate/find the minimum thickness for pipeline installed by open cut method ?, is there a standard/code that addresses it? please mention it Thank YouPipeline, Open Cut, Thickness

I am currently determining the design of the coating, therefore a question arises : Are the compression and tensile yield strengths the same for polyethylene? Thank YouPlastics, Polyethylene, Design

seems to work, thanks with your answer, have a nice day

Hello everyone, I am currently modeling the pipe through the Caesar II application, but there is a problem that I face is about Bend. The picture can be seen below. Is there a suggestion to overcome this ?? Thank You

Thank you all, i appreciate it

Thank you for your answer Maybe I'm more suitable to ask it like this, If we are faced with a choice between LSAW and SSAW in gas pipelines?, how do we determine it, is there any calculation?, I've seen ASME B31.8 (longitudinal joint factor) and it turns out that there is no difference between...

Hi, I'm currently working on a project for a gas pipeline. I am confused about how to choose between LSAW and SSAW, the material used is API 5L. Both have the same longitudinal joint factor. Is there a way to calculate the safety factor between the two in the design stage? I'm currently looking...
