Answer from Werner Sölken
Hi Alaa El-Din Antar,
Your question comes when I want to write a new article.
I've had your question earlier.
I am trying to describe this subject right and correct, but it takes a lot of time and knowledge.
Currently I am in contact with several paint companies.
What I hear is completely different.
Each company has its own policies and objectives.
Perhaps the various American standards give an answer.
I have yet to find out.
Currently, I can not really help...
greetings Werner
Question 159.. i must say, i was impressed
This email should be directed to the Website Supervisor and/or upper management..
I came across your web site while searching for some information about flanges.
The page that opened was about types of flanges. I must say, I was impressed.
The person or people who compiled the information, formatted it so nicely, laid it out so it flowed so well, must be commended.
I liked what I saw so much that I started clicking the other tabs to see what was available.
From Valves to Bolts to Steam, everything is so professionally done!
Even the advertisements were reasonable and not distracting.
I design publications, forms, flyers, and newsletters for my company so I can truly appreciate the thought and effort that has gone into your website.
Great job people! I'm emailing a link to my boss so he can see your website too.
Thank you for having such a valuable resource(s) available on the Internet.
Sincerely,
Kevin Hopkins

Question 158.. can we switch back forth between si units and imperial units?
This is an excellent website. Is there any way we can switch back forth between SI units and imperial units.

Answer from Werner Sölken
Hi David,
Thanks for your compliments.
Is there any way we can switch back forth between SI units and imperial units.
No, not at this time.
In a few weeks, I will show both units.

Question 157.. what kind of water should be used for a leak test?
Estimados Srs.
Agradeceré mucho nos puedan apoyar para nos puedan indicar los parámetros químicos que debe cumplir el agua para usarse en una prueba de estanqueidad en un condensador hecho en acero inoxidable 304L.
Muchas gracias por su apoyo
Answer from Werner Sölken
Use Demineralised water.
Demineralised water is water completely free (or almost) of dissolved minerals as a result of one of the following processes..
- distillation
- deionization
- membrane filtration (reverse osmosis or nanofiltration)
- electrodyalisis
- or other technologies
The amount of dissolved solids in water that has followed one of these processes could be as low as 1 mg/l and is in any case always less than 10 mg/l.
The electrical conductivity is generally less than 2 mS/m and may be
even lower (<.. 0,1 mS/cm).

Don't have a FIT over miss-fits
Remarks from Werner Sölken
Recently I saw a picture incl. article from James O. Pennock.
In the picture you can see, that all kinds of forces are turned off, to get a piece of pipe to each other.
20 years ago we have done so, but not anymore!
James, keep your Florida location, but try not to interfere with your standards.
greetings Werner
Question 155.. Wat is Killed Steel?
In the Netherlands www.wermac.org get often the question.. what is killed steel?
Below, a short answer in Dutch
Answer from Werner Sölken
Staal dat volledig gedeoxideerd is, door toevoeging van een middel zoals silicium of alumimium, vóór het gieten.
Praktisch ontstaat er geen gasontwikkeling tijdens de stolling van het materiaal.
Killed Steel wordt gekenmerkt door een hoge mate van chemische homogeniteit, afwezigheid van porositeit, en daardoor een dichtere structuur.
Also take a look at the english version about Killed Steel.

Question 154.. Is it allowed by asme viii-1 to create a blind flange...?
Dear Sir,
I have seen your website for quite awhile and i thought it was just a random websites but seeing it inside, i found that it has tons of information for piping and pressure vessels.
well done sir!
I have question here if its alright.
1. Is it allowed by asme viii-1 to create a blind flange machine from thick plate?
2. What is the ndt requirements?
Thank you very much.
Regards,
John G
Answer from Werner Sölken
Hi John G,
Yes, you may manufactured a blind flange from a plate.
The plate material should be in accordance with, e.g. ASTM A105, as it relates to carbon steel.
A material certificate should be available, and the batch (charge) number should be, by an approved body are stamped into the flange.
Use ASME B16.5/B16.47 for the dimensions and e.g. ASTM A105 for the material quality.
What is the ndt requirements?
In principle, there are no further non-destructive examinations necessary.
That, however, depends on the mind of your customer.
By the way ... thank you for your compliments on my website, and my name is Werner.
greetings Werner
Question 153.. i found a few references on prelude flng, so thanks for that
Dear Sir,
I found your website very informative, and you have obviously put a lot of work into it.
I wanted to personally thank you for producing such a good website. I started sharing the address with my Project / other Disciplines engineers, so that they learn the basic piping principles.
Additionally, I found a few references on Prelude FLNG, so thanks for that.
I hope that the past few and next youtube FLNG videos will give younger generations some interest in FLNG and piping in particular!
Kind regards, James Nafraicheur
Answer from Werner Sölken
Hi James,
The "Prelude" project is so amazing.
The challenges for "Shell" are huge.
If you have more images or videos, let me know.
By the way ... thank you for your compliments on my website.

Question 151.. does wermac ever get quotes requesting supports for fiberglass pipe?
Hello,
Does Wermac ever get quotes requesting supports for fiberglass pipe? We have a line of supports for fiberglass and HDPE supports that we can provide you pricing.
We would like to work with you do not have a source for supports for fiberglass and HDPE pipe.
Thanks
Fred
Answer from Werner Sölken
Hi, Fred
I have often seen the advantage of fiberglass and HDPE supports, but I'm not the one who can make decisions about.
My client(s) determine what needs to be applied.
If you want, I can show your full address and the attachments that I have received.
