Hi All, We need to make a small 16 gallon tank to act as a intermediate tank between day tank and filling machine. The tank needs to be designed for 14.5 psi internal pressure and full vacuum. MOC is AL6XN and tank will be designed as per ASME code but it will not be stamped. I want to know for...

Hi all, In my area of work we frequently use stainless steel (316L) and copper tubing in FMCG production plant. I want to know if stainless steel ( say SS 304 )and copper hardware are required for supporting those tubes respectively? Is there any chances of galvanic corrosion or any other...

All, I want to know if design pressure of any vessel is 15 psig whether it comes under pressure vessel category and its stamping is needed? Thanks in advance.

Hi All, I want to know whether 2B mill finish is equivalent to finish with 32 micro inch average roughness (Ra). Context is for sanitary application. As per 3A, the surface roughness should not be more than 32 micro inch. I was told that 2B mill finish is equivalent to 32 Ra finish. Just want...

Hi, I want to know that pad flange on tanks are different kind of flange or B16.5 flange? Thanks in advance.

Hi All, I am working on modification of SS 316L atmospheric tank. The design internal pressure is 10 psi, design external pressure is 2 psi and design temp is 250 deg F. As per the drawing the vessel is manufactured as per ASME Code section VIII Div 1 but it is not inspected and stamped. My...

Hi everybody I have a basic question. Suppose I need to provide a support for a section of piping which have valve and some instruments on that. The weight of valve and instruments in catalog are given as 75 kg. So do I need to consider it as weight of valve and in calculation use 75 N for...

Hi Everybody! In many pipe specs it is mentioned that be sure that the slope is not reversed at any point. What does it mean? Does it mean that through out the complete piping the slope should be in same direction ? or does it mean that the slope should not be against the flow direction...

All, Do Positive displacement pumps also suffer from cavitation like centrifugal pumps? Is there any NPSH requirement for such pumps? Thanks

All, Let me start my quest with this subject. My question is does the location of high point vent depends on flow direction? And does the number of H P vents depends on the length of piping? To be more precise, attached file is part of routing for Amine Oxide. Which is suitable location for a...
