Hi Artisi The number has not been finalized. The preliminary numbers are listed below. The flow will be 1000m3/h, and DP will be 1400 kPag. At this stage, we already talked with several European suppliers. However,the project is located in NA, and we prefer to find some local suppliers. Hi...

Thanks for your help EdStainless It does not have to be a Hydraulic pump. I actually prefer to have a 90 degree gear operated drive. I already talked with Sulzer. They can provide the pump but they will not package it. I will talk with peerless later. Thanks

Hi I am looking for a diesel drive seawater lift pump package which including pump, diesel engine, piping, instrument etc. similar to the one in the following link https://www.framo.com/globalassets/pdf-files/Hydraulic-firewater-pumps.pdf Could you give me some vendor's name or website in...

Considering CA on Flange thickness typically is not required. Reason: 1. your flange both sides are not directly contact with the liquid. so there is no corrosion. 2. Flange design is typically rigid design. a local corrosion (such as inter corner of flange) will not affect integrity of flange.

I know CBI can do this Job. If there is anybody else who can field erect large spherical vessel in north american? Please give me name or website. Thanks

some background info from API meeting about why and how the change happen in 12th version API 650. 1) Open top tanks are subjected to no roof wind uplift. Under current rules, controlling formulas see 60% of the design horizontal wind in the empty condition. This results in overturning that...

I am working on a tank which is required non-anchorage design due to civil reason. the tank is equipped with supported cone roof ( roof is supported by structure column from tank floor and beam). The 12th edition API 650 is giving two criteria for us to choose. Unanchored tanks shall meet the...

I am working on a fatigue pressure vessel (Based on Div 2 critiria). The question is that if the vessel can be designed, fabricated and registrated as per div 1 vessel and only add div 2 fatigue calculation on top of this? or the whole vessel has to be designed, fabricated and tested as per...

Artisi 1 pump type OH2 2 YES, both meet requirement now.(after adding the ring) 3 on test loop. the pump is still in manufactory's shop. 4 The curve is availabe. but I am sorrym, can not post the test curve here. Thanks

Thanks for all of above advice. the pump have been tested, yes, the NPSHr became lower than requirement after installation of the ring ( I even do not know how to call it). However, the power efficiency became lower than expacted number. Right now, we do not have any other choice. Since the...

We have ordered a large liquid centrifigul pump (over 500HP) . After running the test, the NPSH can not meet the requirment. So the vendor offer two options to us. 1. add a inducer which I can understand but is not allowed by the client's spec. 2. install a fixed ring at inlet of pump. It will...

MattHeilandt Which window are you talking about? Could you kindly check my attachement? Please note, the right bottom the unit has been setup to SI. Thanks

I try F7 to mode options. It does not work for me.

I am working on a new project which are using SI unit. However, the wizard always use US unit as default when I creat a new vessel. Yes, I can change all of them to SI unit after the wizard. However, Tom, Do you know how to change unit during the wizard? It will make my life easy. Thanks

Since I start this question, I report what happen at the end. As per the local jurisdiction, A new handhole is added at the center of the head and the inside surface of the close weld will be inspect by a camera. thanks guys

In Chinese pressure vessel STD GB-150, you have to test it per 1.5Xdesign pressure. However, if your vessel is design based on ASME VIII Div 1 with U stamp, I believe that the Chinese "Boiler Pressure Vessel inspection and supervision House" may also accepte it. In this case, You can do...

Please check following link. It will answer your questions. http://www.codeware.com/support/faq/1062.html Good luck!

I am working on a 60 years old heat exchanger. The client want rerate it to higher operating pressure. However, it use clamp structure instead of girth flange see attached drawing for details. I can not find any calculation method for this structure. The only clamp calculation method is ASME...

the largest nozzle is 3" only. the only way to inspect it is to insert a camera inside the vessel. I know somebody use it to inspect internals (nonpressure parts) and never saw anybody to use it inspect weld seam. Is here somebody have the experience? THX
