Thank you all for your responses. GHartmann and LittleInch, There is no specific issue I am having with any pump. I was just asking if more experienced engineers had experience with "horizontal pumps for condensate service in a Combined Cycle Power Plant utilizing an Air Cooled Condenser". I...

Hello Forum members, Does anybody have experience with horizontal centrifugal pumps for condensate service in a Combined Cycle Power Plant utilizing an Air Cooled Condenser? This is really a rare design and I would like to know if someone has experience with it and how it works out. Thanks...

Many thanks Mr. Penn and IRStuff. I totally understand and agree with you that this matter is variable and depends on each company's experience. I worked with big companies before and I know. The thing is that this company is new and they are still in the beginning of the Engineering business...

Mr. Penn, Many thanks for your support! Your website is indeed very informative and useful. As a matter of fact, I have already added it to my Favorites previously, but never thought it would also cover this kind of issues. Anyway, really appreciate your help!

Hi everybody, I moved to a new company and they are still getting started with Engineering work. They want me to help them in predicting the size of a piping job so that they can budget it accurately (to a certain acceptable extent). Unfortunately, my experience is limited and did not get a...

BigInch, you are right about pump manufacturers cutting down on allowables to be conservative and build lighter (less costly of course) and, consequently weaker pumps. Just want to share something with you. It seems (I presume) that the majority of your experience was in the Oil&Gas Industry...

Hi there, I would like to know if anybody has any experience with FRP Tanks and if there is a simple method for determining or calculating the flexibility factors (axial, bending, and torsional) for FRP tank nozzles, because WRC-107/297 is inapplicable, since WRC-107/297 was based on the...

Hello Everybody, I have a very interesting problem I need your help on. I'll try to make it as short as possible. While stress analyzing the Main Steam and Cold Reheat lines for a 650 MW plant, I proposed to relocate the HP-Bypass valve away from the turbine (by about 14 [m]/45 [ft]) because...

Indeed a234f56. zdas is only trying to help you, so accept his advice in a constructive way. We have to appreciate that we have highly professional senior people sacrificing their valuable time -as zdas stated- sharing their experience and helping junior people like us (I consider myself junior...

Hello everyone, I would like to get clarifications for a few things in Appendix II of the ASME B31.1 Code: 1. When determining P1 (see Section para II-2.2.1, (A.1)) at the discharge elbow, what are the "a" and "b" factors in the equation? 2. Why does P1a = P1(P/P*)? Is P* the critical...

I am a junior engineer and would appreciate if somebody would explain what is the "Shallow Shell Theory" which is the basis for Bijlaard's work in building the Local Stress curves for Spherical and Cylindrical Shells and which was later adopted by the WRC? Thanks
