What are the points to be considered for this change.
1.Additional  line number to incorporate the size change to be made?
2.Welding to a new piping to an old piping -how this is to be analysed?
3.What all to be considered for this design modification.(MOC)

I need to find out what it is so I can purchase them and include in my model. I do know it's Sch 10 304 SS. I'm wondering if it was made from two 90's?

                        <content:encoded><![CDATA[Good day,

Just wondering, if flangeolet can be forged and supplied by Vendor up to 24", why are for some larger connection (example 40" x 10") , combination of weldolet welded to weldneck flange is used?
Is it just because the branch table in Piping Material Specs indicate for such connection, weldolet shall be used instead of flangeolet?
But again what is the basis of creating the branch table limiting usage of flangeolet to certain sizes (in most project i have worked, up  until 2" only)?

Request for your expertise to enlighten me on this matter.
Thank you.

AjakPiper]]></content:encoded>

<strong>Manual Valve Tags on P&amp;ID's</strong>

Manual valve tags are sometimes shown on P&amp;ID's for reference in operating procedures. 

Do you still see these tags on P&amp;ID's or is this something that is no longer current. I understand that some clients require these tags, but I want to get a feel from the general piping population what is done in the 21st century. Especially with the use of intelligent P&amp;ID's, it may sound easy, but it still take a bit of additional effort.

What is the norm on your recent projects?

                        <content:encoded><![CDATA[I would welcome opinions on configurations of Control Valve Assemblies. In most Piping books and Company standards the assembly will look similar to attachment i.e. with bypass line directly above control valve. In my experience as client piping engineer this is the common configuration modeled by Contractor(s) and presented during model review and our comment is always to demonstrate how to remove control valve which is typically by mobile crane or by slinging from overhead beam or similar with the problem being that bypass line will foul. Our maintenance people always quite rightly want a straight lift to maximize safety and reject solutions such as slinging at an angle and counterbalancing with rope or additional sling. Sometimes at grade level we can accept trolly/forklift underneath valve but this is limited by valve size and weight.

At start of every project I highlight this to Piping Leads and am assured that they will consider this in their material handling but invariably becomes a client comment during review and subject to rework. Present project (FEED) I have had it written into basis of Design and stated that bypass to be offset to allow valve removal although come model reviews I expect to have to address again.

I would welcome some feedback and if concur that I am correct why is it never addressed in literature, one of common replies by experienced pipers is that this is the way that it is always shown in books etc.

Regards.

                        <content:encoded><![CDATA[Hi all,

I am working on a project in which 25/31.5 MVA transformers are supposed to be protected by fire water spray system and it will be controlled by Air operated deluge valve. Instrument air is not available in transformer surrounding area, so we have to plan AI supply from OSBL pipe rack, which is 300 meters far from deluge valve location.

My question is<strong> " can we run AI header underground? if not, why?"</strong>

Line size 2" / 3"
Pipe material - CS Galv
Design pressure - 10 Bar
Design temp. 65 Degree C
Operating pressure - 7 Bar

Pipe length required in UG = 200 / 250 Meters


If anyone has relevant experience, please share

                        <content:encoded><![CDATA[Beauregard Gustafson

You may say, Who is Beauregard Gustafson?  I have never heard of anybody by that name. You are right, you may have never heard of him by his full formal name but you know him by his pseudonym (alias or nom de plume).  

Beauregard Gustafson is better known as Beau-Guss (pronounced ˜bo-gus" (1)). He is famous for his often wild and inaccurate statements and ideas often considered not genuine; counterfeit; spurious; or a sham. 

Beau-Gus is quite a versatile individual.  He seems to get around to almost every profession, industry, trade and craft.  He appears to be the classic 'Jack of all Trades, master of none'. As he moves from one environment to another he leaves a trail of false hoods and ideas that can get people in trouble.

You can not always recognize a Beau-Guss statement or solution from the real thing because they all seem to sound logical.  They also seem to be new and different from the current tried and true method which has a long standing success record. 

The best defense against these new sounding Beau-Guss ideas is to do some research and find out if the new idea has undergone any actual field testing.  


  <li>Who did the tests?</li>
  <li>How many tests were done?</li>
  <li>What were the variable of the tests?</li>
  <li>Did the actual testing cover the evaluation of all the different variables?</li>

Beau-Guss has made his way to the Piping field on a number of occasions and has left his questionable foot prints.  The results of these visits (and the invalid ideas) often leave people in a state of outright confusion which results in wasted time, effort and revisions to designs because of the miss-direction. 

The list of Beau-Gus Piping Ideas includes the following (along with my judgment of them):

<ol>
<li>Two Fittings (2 elbows, an elbow and a Tee, an elbow and a Weld neck flange, etc) cannot be welded directly together, they must have a Pup Piece between them. <font color="#FF0040">(False)</font></li>
<li>Pump Suction and Discharge lines (implied every pump suction &amp; discharge line) should be fitted with a Flexible Connectors to reduce Forces on the Nozzles. <font color="#FF0000">(False)</font></li>
<li>Pump Suction lines (implied every pump suction line) needs to have 10 pipe diameters of straight run between the reducer and the nozzle flange (5 diameters was later accepted as an alternative). <font color="#FF0000">(False)</font></li>
<li>Pump Discharge lines (implied every pump discharge line) needs to have a minimum of 10 pipe diameters of straight run from the nozzle flange to the reducer or first elbow. <font color="#FF0000">(False)</font></li>
<li>Pump Discharge lines (implied every pump discharge line) shall be fitted with two Check Valves (CkV).  These CkV shall be different types and shall have a minimum of 10 pipe diameters straight run upstream of the first CkV, 10 pipe Diameters straight run upstream of the second CkV and 5 pipe diameters straight run down stream of the second CkV. <font color="#FF0000">(False)</font></li>
<li>Strainers in pump suction lines and Steam Turbines supply lines should have a minimum of 10 diameters straight run upstream and down stream. <font color="#FF0000">(False)</font></li>
<li>Pipe Racks (ISBL and OSBL) shall be sloped (graduated elevations) so Steam lines and Flare Lines will drain in the direction of flow. <font color="#FF0000">(False)</font></li>
</ol>

I am sure there are others examples of Beau-Guss thinking out there.  If you know of any others please feel free to add them to the list.
