[MW:986] Re: Root under cut

Dear Atul,
If you are concerned more about to avoid root undercut, the only thing you need to do is to demagnetise the job near to wep and on wep with the help of demagnetising equipment and weld after demagnetising. You will get a smooth weld without any undercut.
For one of our projects, we have over come the undercut problem by demagnetising and welding. This is for your information and for ferritic materials only.

Regards
Ramu

There is no such clear demarcation, can vary from institution to institution

 

ASM classification as below

Plain carbon steel (<0.2C called as low carbon steel)

LAS <= 8% of total alloying elements

HAS > 8% of total alloying elements

 

By this all your below netioned materials can be called as LAS (except P91), where as even P91 comes under LAS family  in case ASME BPV

 

More views are welcome!

dear members,

 

how can we classify the alloysteel materials as low alloy /highalloy.

 

if we can classify  then P 91/P22/P11/16M03/DINWB 36

comes under which category.

Dear All,
Just to add further to this,
Avesta P12-R Basic (ENiCrMo-12) is best suited for welding UNS S31254.
The
Avesta P16 Basic electrode confirms to ENiCrMO-13 and is specifically
designed for welding 654SMO (UNS S32654) grades.

UNS31254 is similar to Type 254SMO of Avesta polarit; you may contact
them for their recommended combination (Avesta P16 or P12-R basic etc.)
ERNiCrMo-3 (AWS Specification A5.14) or ENiCrMo-3/ ENiCrMo-12 (AWS
Specification A5.11) can be used for depositing, depending on the
process you may choose. E309LMo also can be used for barrier layer.
Avestapolarit has 805 flux which can be used in case of SAW

Sandvik also got similar combination such as Sanicro60 etc...

For strip cladding Soudokay has got some combinations, such as
Soudotape625 with flux NFT201/EST201 (refer their catalogue)

UNS31254 is similar to Type 254SMO of Avesta polarit; you may contact
them for their recommended combination (Avesta P16 or P12-R basic etc.)
ERNiCrMo-3 (AWS Specification A5.14) or ENiCrMo-3/ ENiCrMo-12 (AWS
Specification A5.11) can be used for depositing, depending on the
process you may choose. E309LMo also can be used for barrier layer.
Avestapolarit has 805 flux which can be used in case of SAW

Sandvik also got similar combination such as Sanicro60 etc...

For strip cladding Soudokay has got some combinations, such as
Soudotape625 with flux NFT201/EST201 (refer their catalogue)

[MW:977] Re: Root under cut

Root undercut is end result of high Current, travel speed, uneven root gap and some time because of surface tension of the material and last but not least because of welder human error. To avoid under cut mainly focus should be given on current and travel speed. Undercut problems are not envisaged with cellulose electrode if proper welding parameter set along with good skill welder. Some time re shuffling of root welders also help to reduce down root related discontinuities.

[MW:969] RE: 947] RE: 865] PED Harmonised Standard for Design

Friends, recently I attended one seminar on “Awareness training seminar on CE Marking – Pressure equipment directive” conducted by TUV India. I share below my learning:

 

Any std. adopted and published by CEN (European Committee for Standardization – Comite Europeen de normalisation) is known as EN std. (European standard). Incase it is published in “official Journal of the European Union”, it is known as “Harmonised Standard”. For example, PED 97/23/EC has been published in official Journal of Europa under no. L 181 on 09.07.1997.

 

All std. published in “official Journal of the European Union” can be seen at:

http://eur-lex.europa.eu/JOIndex.do?ihmlang=en

 

You can also search and download the harmonized std from above mentioned site.

 

“BLUE GUIDE” are also available for the interpretation of harmonized stds.

 

If anyone would like to place the product in the European Market, it is mandatory to provide “CE Marking” on it. And to have “CE Mark” one need to follow the appropriate regulation (like PED for Pressure Vessels) and the equipment has to be approved by “Notified Body” if applicable.

 

Hope the above information would be useful to all.

 

Best regards,

Subject: [MW:865] PED Harmonised Standard for Design

 

Just the below link for more information, interesting one

http://www.unm.fr/en/general/en13445/

 

published hormonised stanadrds for Directive 97/23/EEC can be seen at

http://ec.europa.eu/enterprise/newapproach/standardization/harmstds/refl

ist/equippre.html

and

http://www.newapproach.org/Directives/ProductFamilies.asp?97/23/EC

 

The attached list contains references to harmonised standards for

pressure equipment and harmonised supporting standards for materials

used in manufacturing pressure equipment.

 

The follwoing pretext taken from a CEN link may be helpful

A harmonised standards is a standard considered by the European

Commission as satisfying some of the directives essential safety

requirements.

 

Harmonised standards are covered by three types of European  Standard:-

 

    * Harmonised Product Standards

      These are application codes  that cover the design and manufacture

of Pressure Vessels, Boilers and  Pipework

 

    * Harmonised Support Standards

      Welding, NDT and other  standards that supplement the application

codes.

 

    * Harmonised Material Standards

      A material specified in a  harmonised standard will satisfy the

requirements of the directive in terms of  ductility, toughness and

strength but does not guarantee that the material will  be suitable for

a specific application.

 

 

Each harmonised standard will contain an annex stating  which essential

safety requirements it satisfies.  The advantage of using these

standards is that no additional justification is required that essential

safety  requirements have been met and providing the standards have been

correctly  applied the design of the equipment can not be challenged.

 

Another advantage of using Harmonised Standards is that they  provide an

interpretation of the directive.  For example if a pressure vessel is

to operate below zero the impact tests on the material and welding

procedures  have to be carried out the lowest operating temperature the

vessel will  experience according to ESR 7.5.  This is not current

practice as far as either  PD5500 or ASME VIII is concerned as both

these standards permit, under certain  circumstances, warmer impact test

temperatures.

 

Harmonised Standards are not essential, any appropriate  standard can

used but the satisfaction of essential safety requirements must  proved.

Both PD5500 and ASME VIII have produced annexes stating how and which

essential safety requirements they claim to satisfy, these annexes have

not been  approved by the European commission and therefore neither

standard can claim to  be harmonised.

 

Note PD5500 has nothing to do with the PED, it is simply the  latest

revision of BS5500, it no longer has the status of a British Standard

because it will conflict with BSEN13445.  It is now a  Published

Document rather than a standard,  This will make no difference to it  as

it will continue to be supported as long as its popularity remains

 

The harmonised standard for the qualification of welding personnel is EN

ISO 9606, for operating procedures it is EN ISO 15614. (Note EN ISO

15614  only satisfies the requirements of E.S.R 3.1.2 it does not

satisfy the requirements for welding consumables stated in E.S.R 4)

[MW:967] Material equivalent software

Dear Mr Sachin

 

We have come out in a long way since past 13 months with nearly 500 members now to help you, me and all of us to enlighten our knowledge in the process, devoting their time. We have debated and decided in the past not to distribute any copyright material (such as codes, standards, company specs etc) in the group. I appreciate time/efforts by the moderators; it is a part of the process, no personnel issues.  No more issue on the subject pl. let us stick to the theme of the forum, on sharing technical experience and helping out newbie’s in the industry

 

Discussion is an exchange of intelligence

Argument is an exchange of ignorance.

 

I am just pasting here one of the discussions posted by our group member in the past

 

Dear All,

My advice stands. What you might choose to do within your own company is one thing - I'm sure your company lawyers can help you on matters of copyright. What you post to a world-wide, public group is another. For your information, I am a registered member of this group. If the originators of the group intended it to be a private, internal group, they shouldn't have done it through Google - it's the gateway to the entire world!

 

I think that this is a very useful forum and a splendid way to share advice and information - just please be careful about copyright issues. The API in particular seems to be very hot on them. If you buy a digital (PDF) version of their specs now, single-user versions are literally that - you'll only be able to install it on one machine and you can only print it once. Which is great if your printer runs out of ink half-way through. I've gone back to buying paper copies.

 

I do consulting work on various oilfield problems and I teach materials, corrosion and welding matters to M.Sc. students at the Robert Gordon University in Aberdeen, where they are VERY sensitive about copyright issues.

 

Regards to all and keep up the good work!

 

Owen Jenkins.

Subject: [MW:960] Material equivalent software

 

 
 
Dear Friends,

At times we come across situation where due to unavailabiity of certain material we have to search equivalent material.
Its time consuming process to find equivalent material.

I just found one of the software which can find equivalent material for almost all countries standards.

Please copy paste below link

http://www.ourmetals.com/index.php?t=06&c=england&cat=13&subcat=116&step=4&rid=14&rid2=0&rid3=5

However this software is not free.Hope ,if any one can find crack for it?Please let me know if you can.

Also results of query for equivaqlent material is shared free on site which we can make use of it,if we are lucky enough to get our choice of material

Please copy below link to see results of query raised for equivalent material by many people.

[MW:965] [piping_valves] Flange Reduced Rating


Reduced rating is common where a conservative approach is applied in defining the piping materials while shaping the piping material classes.
Conservative... in the context of reduced thickness of pipes and fittings and having in some cases a reduced pressure rating of flanges. Subjectively, handling such cases is a little bit complex due to the nature of broad aspect of the parameters involved.

In a process plant, there will be few border cases of design conditions in the process streams, by which I mean the borders of the ANSI B16.5/B16.34 rating tables. On certain cases reducing to the next lower pressure rating will benefit a turnkey contractor, considering down the line cost benefit depending upon the quantum of piping involved in those streams. During such cases the piping material engineer who optimizes the PMC-piping material class concludes with process engineer to reduce the design condition.

In these border cases there are two aspects.
1) The simple safety factor reduction of the process condition judged by the process engineer.
2) The process stream may not be subjected to the defined design condition continuously, but on a cyclic or only for a short period of duration. ANSI B31.3 / 1 allows such temporary surging under certain criteria (Refer the code for details). Under such limitations, the piping material engineer works/designs the PMC with reduced pressure rating conditions also called as a STC - short term condition.

So in conclusion such conservative approach helps in avoiding Over Designing the piping system with the ANSI code as an excuse/backing. Addtionally, such concept has significance when the quantum of piping is extremely high and if the streams are in higher temp. ranges where material selection plays a very important role.

With regards,
Kannan

[piping_valves] RE: 941] Flange Reduced Rating





Can you please elaborate!

Is it something related to DIN flanges? I don’t know exactly but probably the P/T ratings are reduced while revising the new EN standards (PrEN1092?) for PN based flanges.
