Dear Friends,

I am making fixed roof cylindrical oil storage tanks as per Indian
Standards IS-803.In section 9.3.5 it is mentioned about circularity
and shape.There it is mentioned about verticality & circularity
tolerences.Also it is mentioned about peaking and bending of welds
there..

1.Peaking of vertical weld joints measured over an arc length of 1 m
shall not exceed 12 mmm.

2.Bending of horizontal weld joints measured by a straightedge of 1 m
length shall not exceed 12 mm.

My questions are..

1.What is meant by this peaking and bending there?
2.How we will measure these factors?
3.How would the unit "millimetre" will come for these factors
measurement?
4.Is these 2 measurements are important in tank fabrication,if I am
checking vericality & circularity properly?

Re: [MW:5325] silicon content

Mr Soliman is correct, I misread the part on the chemical analysis table

Dear all.

i have checked the SA 106, and i found no limitation in Si%,
but, by experience, in most material test reports i have ever checked, the Si content is (0.2-0.35%) for the carbon steel SA106-B pipes.

- i recommend using the IIW equation in evaluationg the carbon EQUIVALENT, not the API 577 RP Formula, Because the second formula is written as for an example ( i.e : NOT MANDATORY).

Re: [MW:5324] Peaking & Bending Measurement of Welded Joints in Cylindrical Storage Tanks....

Mr.Jose,

Reply to your questions are as follows,

1.Peaking & banding is nothing but the profile of the tank i.e while erecting the shell plates the curvature to be maintained.

The shell plates rolled to a radius to be maintained till the welding of joints completed.For this purpose only the curavture of joints are checked.

For vertical joints of tank curvature is called as Peaking.

For Horizontal joints it is called a Banding.Banding is also called a straightness.

2.These can be measured by making a template of 1 mtrs length.Template shall be of a wooden board .Mark the radius of the tank shell in an wooden board and cut accordingly.One side of the template shall be used for peaking and the other side straight side shall be used for banding.There is no specific requirement for making a template just make for easy handling

3.Keep the template-straight side on the centre of horizontal joints so now you will find half(500mm)on one shell course and remaining half on the other shell course.Take the measuring scale and measure the gap between joints.

Keep the template-radius side on the centre of vertical joints and measure the peaking so now you will find half(500mm)on one shell course and remaining half on the other shell course.Take the measuring scale and measure the gap between joints.
4.Peaking & banding are the important parameters to be checked while constructing a tank because circularity & verticality is checked but at the same time on the tank weld joints Peaking & banding are checked to maintain the profile and to avoid local buckling of weld joints.

RE: [MW:5322] unequal thickness in UCS66

Pl refer para UCS 66, which gives the creteria for governing thickness of varous components in a vessel, including disimilar thick joints, such as nozzle to shell, with ref to figures given elsewhere in this section. If you need more info can provide your joint configuration.

RE: [MW:5321] Peaking & Bending Measurement of Welded Joints in Cylindrical Storage Tanks....

You can make a template from a steel sheet / scrap plate with radius of template equal to your tank radious with an arc length of aprx 1 mtr. place this on your tank and if you are getting greater than 12mm gap, needs rectification. Similar way use 1 mtr steel rule as straight edge to check verticality.

Your 4th point itself is an answer to your query. How do you intended to check verticality and circularity?

My job is Carbon steel and thickness is 20 mm. For radiography I have to select the IQI set as material group as “1” and wire type set as “A or B or C or D”. Can you please guide me how to select the set identification number based on thickness of job.

Thanks in advance

Re: [MW:5317] Expiry date

Dear Sandeep,

As electrode manufacturer we recommend maximum 3 years storage under recommended conditions. If you redry them according to the manufacturers recommendation, they will be returned to mint condition. This is sound engineering practice. If the electrodes are packed in an air tight package, they can technically be stored for a very long time. However, there is a limit to how long time documentation is kept by the manufacturer, normally not more than 10 years.

Best regards,

Claes Gillenius

Is it Code (Sec.IX or Div.1 ) requirement to conduct DP test after PWHT ?.

If it is code requirement, pl. provide the reference from code.

if any code interpretations available, pl. provide the same.

Re: [MW:5310] Re: DP test Requirement in Overlay PQR.

Irrespective of yr PQR, code req etc Penetrant testing (PT) has a meaning and purpose if it is done after SR and final machining.

This does not preclude testing at different stages of manufacture (i.e)
interstage ,PT after complete welding and machining prior to HT.

[MW:5305] ask about comparison table material GB ( chinesse ) to ASME

Hello, my name Dean....i'm new member of this group.

Right now i'm doing some boiler project using material from chinesse.
Can someone help me with the information about chinesse material in
boiler, especially about the material comparison table to ASME.

thanks for the attention before

RE: FW: [MW:5304] group of SA517

Dear Ali,

I have attached a comprehensive guideline from ISG (Now Arcelor) for your reference. You need to work out a full fabrication (including forming) and welding/PWHT guidelines so as to handle Q&T steels successfully.

Typically SA 517 grade steels would require some degree (100-150 deg C max) of preheating for successful thermal cutting depending on the thickness.Following cutting the kerf and cutting burrs shall be smoothly ground to remove all serrations. LPI or MPI shall be done on all cut weld bevels.

While forming the dished heads, some form of warm forming typically below the code recommended PWHT temperature would always be advisable. If forming method is hot forming them heads should preferably be subject to Q&T operations again. You may need to contact and discuss this aspect with the steel mill, before proceeding with forming and other fabrication aspects.

Typically welding electrodes would be E-10018/11018M or matching GTAW/SAW consumables. SAW shall be done with extreme control on welding heat input.

The attached document is quite detailed, please read though and feel free to raise any queries.

Thanks.

Dear Goswami

Thank you for useful information.

I work in a fabrication pressure vessels project, that used from SA517 gradeB,F.

unfortunatly in most cases during prepration of joints, some cracks in base metal founded.how can dealing with them?

do you have infrormations about forming methods of shell & head? or in which documents can i found?

Dear Ali,

SA- 517 is a high strength quenched and tempered steel, which comes in 6 grades, Grade A, B, E, F, J, P. You may find all the details in ASME Sec-II, Part-A.

Coming back to this steel, it is :-

· Quenched—to refine the grain, to enhance the UTS. Talk about any alloying element, Cr, Mo, Ti, V, Bo Nb/Cb, you’ll have in this steel. This steel have very little ductility in as quenched condition

· Tempering – to enhance the ductility(% El), to enhance the notch toughness, reduce the hardness.

A combination of both the above heat treatments provides a balanced mechanical properties in this steel. This answers point1 of your query.

ASME Sec VIII, DIV-1,UCS-66, does not deal with this steel, UCS chapter is for carbon and low alloy steel only .

SA-517 is covered in great details under UHT. There is no exemption for impact test on this steel. Welding of SA-517, as like any other Q&T steel requires a great control and precautions on welding.

Where are you thinking of using this steel? Let me know if you require further details.

Thanks.

Dear Ali,
for your point no. 1, I would like to say due to quenching in oil/water after heating the object to the required temp, the cooling rate will be very faster, so grain size will be less. In this case hardness and brittleness also increases, so to get toughness in the material we need to carry out tempering.

RE: [MW:5298] silicon content

Dear all.

i have checked the SA 106, and i found no limitation in Si%,
but, by experience, in most material test reports i have ever checked, the Si content is (0.2-0.35%) for the carbon steel SA106-B pipes.

- i recommend using the IIW equation in evaluationg the carbon EQUIVALENT, not the API 577 RP Formula, Because the second formula is written as for an example ( i.e : NOT MANDATORY).

Re: [MW:5294] DIN Wire IQI Thickness

Wire IQI

Used to assess sensitivity ; quality of technique

Pl refer DIN 54109 (1962); ISO 1027

Wire set 1-7; set 6-12; set 10-16 (1,7,6,12,10,16 represent wire numbers)

3 sets - each set having 7 wires (overlapping with adj set) arranged in GP

usually 2% or lesser value of sensitivity is required for general applications

Smaller no 1% indicates higher sensitivity -critical applications
