Good morning everyone, I have a quick question regarding the image below. The line below is part of a glycol-water system, 304 SS material. The silver piping is 1" NPS SW and the magenta valves are 3/4" NPS SW. Operating conditions are 44 psig and 25 deg. F. The valve on the left side will...

Looking for a little advice and guidance on how to handle a particular situation. I am currently a piping designer for a small engineering firm that is looking to expand. About a year or so ago, the CEO approached me about trying to develop company quality standards for the piping and...

Good afternoon all, Please see the attached file for a reference. We've recently had a string of projects where more and more client's are starting to request the use of these structural beam pipe supports rather than traditional pipe base ells/dummy leg supports. Their reasoning seems to be...

All, I have a question regarding pig trap kicker lines. I'm getting ready to design my first pig launcher/receiver, and I'm trying to review my practices and standards before I get started. As I understand it, for pig launchers, the kicker line should be placed as close as possible to the end...

Hello all, Just looking to ask a general question to improve my own knowledge of the subject. I had an instructor talk about different metallurgy's and the need for isolation (or insulating) gaskets between flanged connections of differing materials due to the galvanic corrosion. Although...

All, I am in the process of trying to gather as much information as I can on the subject. I would like to know some different viewpoints and opinions on the topic of which type of leak test should be performed on piping used in N2 service. The piping is all 2" NPS and smaller, and I believe...

Good morning, We are looking to reduce pressure drop in our pump suction lines. To do this, the suggestion was made to increase the suction piping and nozzle by one line size (from 3" to 4" NPS). My only concern that I'm asking about is that this line reduces back down to 3" further upstream...

An internal discussion has been going around about the effects of a low point pocket as shown below on a pump suction line. I have tried searching for answers but all my results are only applicable to "high" points in a pump suction, not low points. I have already stated my disagreement with...

Good morning everyone, Just had a quick question. It is pretty basic, but I would still like the opinions of some of the experts on here. Please refer to the image below. I have given two examples of a control valve station from a plan view. Station #1 would seem to allow easier access to...

I am trying to find some guidance or literature on bypass piping from pump suction to pump discharge and I am coming up empty handed. This is not a minimum flow recycle bypass. We have a 3" NPS pump suction, 3" NPS pump discharge, and 2" NPS pump bypass that travels from the pump suction to...

Going to be performing the piping design for a pair of rotary sliding vane pumps. This will be my first encounter with this style of pump. I've looked through API RP686 and I plan to contact the vendor once one is decided on and ask if there are any things I should be aware of with the piping...

Process and E&I are developing P&IDs for an upcoming project. The picture I've attached shows the preliminary drawing they have come up with. As I'm sure we all know by now, concentric reducers should not be used in pump suction lines unless the pump is a top suction pump, which this one is...

Just another general question. I am getting ready to take a field trip to do a walk down on some PSV lines for a flare study that my company is getting ready to conduct. In gathering the PSV isometrics from a few years ago, i found that a lot of the PSV discharge piping drops underground and...

Good morning all, I am looking to expand my knowledge on pipeline design and/or B31.4 and would like to know if anyone has good books/articles/reference material that they can recommend. I have had very little experience in pipeline design, but would not like to wait until the project gets...

I would like some clarification on clamp-on pipe shoes. A suggestion has been made to use clamp-on type shoes in lieu of welded shoes due to the client requesting as minimal welded pipe supports as possible. There are some areas where the pipe shoes would need to be used as anchors. My basic...

Can anyone give recommendations for some good books on engineering project management? My interest is more from a process plant engineering and design perspective if there are any books specifically in that area.

Okay, so we have a new situation that I have no experience with and need some wisdom/advice. It will be a little difficult to explain but I will try my best. In regards to construction tolerances for piping... We designed a fire water system composed of the storage tank, pump house, and all...

Just a general question. I was discussing the use of bleed rings instead of a spool piece with a former colleague of mine that is now a lead piping designer at another firm, and he had an opinion about them that I would like to discuss with everyone. The subject of the conversation was how I...

Good morning all, It has been a while since I have needed any guidance, but I am in search of it today. And before I get started, I know this may not necessarily be the correct place for this type of question, however I get them most helpful answers on this forum. First let me give a little...

Good morning, Question regarding the use of both BW and SW components in the same line. Our material engineer is suggesting to use BW fittings (elbows and tees) throughout the piping with SW valves at the control valve station and at the various isolation points. The client spec pretty much...
