Hello!
We are currently doing a project which includes atmospheric storage tanks that is supported by 2m high legs. We're not sure of the reference we need to follow for the leg calculation and bottom shell thickness. API650 is not applicable, isn't it? How about AWWA D100? Any other...
Hi. I am studying how to calculate for the required external stiffener of a transition (rectangular to circular) on a penstock. The penstock is buried and has an external pressure of 0.6 MPa. Internal dimension of the transition is 4mW x 4.5mH to 2m internal dimension.
I am looking at 2 cases...
Hi! I am doing a study for full-pipe, half-pipe, and jacketed design of external coils for atmospheric tanks. I am new on this. Is there any Standard Code specific for this design? I searched API 650 yet I found none. I asked the Client for the required steam condition and still waiting for...
Hello guys,
I have a concern with regards to the required volumetric flow rate for filling a tank to be hydrotested. Is there such thing? I was thinking i need this data for sizing the required pipes and pumps to be used by using Q=AV. Though API 650 gave Water Filling Rate at Section 7.3.6.5...
Hi. Is there a difference between clean washed sand and oiled sand when used as tank based? Because as per API 650, a minimum of 75mm thick clean washed sand is recommended as tank sand base. But existing client's design uses 50mm thick oiled sand. Thanks.
Hello. I am doing a design verification of a tank based on API 650. For its foundation, as per API 650 12th edition Annex B, recommended sand base is 75mm to 100mm clean washed sand. But, client's existing design used a minimum of 50mm thick oiled sand. Is it acceptable? Or do we need to...
Hello everyone! I am designing an LPG Odorant Injection System using mercaptan as the odorant. This is my first time to design such system. I only have the required odorant concentration which is 22.5ppm. How can i determine the required odorant gas flow and injection pressure? Thanks a lot.
