Can you please explain the Zinker method in pipeline installation? Is it commonly used? It seems that I haven't seen it in general pipeline installation books, or is it perhaps categorized under open-cut methods? Maybe you can give me references
Hi,
We operate a natural gas transmission pipeline system running from east to west. However, a report indicates that in the coming years, changes in supply and demand may necessitate reversing the flow direction (west to east).
Could you provide insights on similar projects, relevant...
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...
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...
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 ....

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...
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 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?

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
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...
Hello everyone, I'm currently working on a HDD design project. But I'm stuck in adjusting to the given specification document. The specification states that the longitudinal stress should not be less than 60% SMYS.
The case I'm working on is a 20 in pipeline with a thickness of 12.7 mm. This...
