Hi QualityTime, Yes, you are right. A bare pump means a pump without motor. Actually we can use shop motor if it is available from vendor to perform all the tests. My concern is the necessity to perform the performance test and NPSH test since its operating condition would remains the same as...

Hi All, I have a pump which designed to ISO 5199. To avoid prolong downtime and long lead time, I would like to purchase ONLY a bare pump to keep as spare. Just to check, do I need to ask vendor to include: hydrostatic test, performance test and NPSH test?

Sorry that I didn't write it clear about my question. Basically, we are proposing a pressure vessel with ID: 2000mm and TL/TL: 5500mm. But the client commented the length/diameter ratio (5500/2000 = 2.75) is too small. Usually, it needs at least 3. So, my question is, does the ASME Section...

Hi guys, Anyone knows is there any requirement in ASME Section VIII mentioned about the length/diameter ratio? If no, any guideline/rule of thumb to follow? P/S: It is an 2:1 elliptical horizontal pressure vessel

Hi guys, Below are my client specification on the heat exchanger: Design pressure (ext./int.): FV / 7barg Design temperature (min./max.): -24 / 150degC Steamout condition: FV / 7barg @ 225degC In the mechanical design calculation (PV Elite), I should input 150degC or 225degC? Any problem if...

Hi TGS4, According to local regulation, it is not statutory equipment.

LittleInch, Thank you for the reply. It is a cast strainer, with CS/SS material. There is no quick opening closure. This is a reputable vendor who have been supplying many of this strainer over the world. They sent me a certificate which certified by ABS. In the certificate, it mentioned...

Hi Guys, I would like to buy a basket strainer. Vendor told me that their basket strainer is designed according to manufacturer standard. Just want to know any design code requirement for basket strainer using in oil & gas and chemical industries? Like ASME Sec. VIII or ASME B31.3? Or just a...

The vessel need to be U-stamp. Authorized Inspector advise to specify the MDMT as 0degC. Any concern?

metengr, As mentioned above, I can't use 19degC due to the "high" water test temperature. For default value of -20degC, did you mean to select the minimum temperature for carbon steel, which is -29degC? curtis2004, Process fluid is methanol and location is Singapore.

Hi Guys, How to determine the MDMT for a pressure vessel? Design Data for Pressure Vessel: Code: ASME Section VIII, Division 1 Ambient temperature at site: 19-37degC Design pressure: FV/11barg Operating pressure: 7.9barg Design temperature: 200degC Operating temperature: 61degC...
