[MW:3094] Re: piping and pipleine spacing

Dear Friends,

Question asked by your friend is" i have 3 pipeline burried ...i need to know what minimum spacing is
recommanded....(api 1104/ b31.4)"

So instead of mixing up all information answers should be specific to the questions and convincing openions.

API 1104 deals only with welding requirements ,but the spacing is governed by B31.4/31.8 and national regulations for India {OISD} and some times the CP Design also to be taken into considerations. 

This is my view  considering question pertains buried cross country pipeline and not plant piping and user need to verify with respect the national regualtions requirements and design basis considered during engineering.

Dear Lobo,

 

this is not given is code , this is was the client will be providing the information ,

 

If all is covered in code when why separate client specification are required ?

 

If not provided by the client , the contractor or the consulting party need to step up and inform the client .

 

pleas let all of know your views .

 

Thanks

Dear Daniel ,


 


If you are looking for spacing between the pipe and the ground , it is stated in the API 1104 for p/l ,


 


If you are looking for spacing between 2 welds  usually it is 3  times diameter , or as per client specification


 


Usually this is defined as if the lenght is less will cause distorsion if the pup piec is very small in lenght and at the same should see their is a min spacing of 2 " between the HAZ of the 2 welds , in case u need to come to a smaller lenght .




 


Thanks

You can go for FBE ( Fusion Bonded Epoxy) coating for those bolts.
FBE coating is a good option. But check other parameters and the fluid if its affect the FBE material.

[MW:3092] Re: piping and pipleine spacing

Gentlemen,

it shall be informed by the client i.e for ARAMCO they are requiring 1 M distance or gap in case of intersecting pipes measured from top of the lower pipe to the bottom of upper pipe , while for parallel buired pipes it shall be 3 meter.

[MW:3089] Re: 3083] Re: Regarding the NDT to be carried out for 60 mm thick austenitic stainless steel plates

Dear Mr. Vagal,
1. For radiography of 60 mm thickness of S.S. C0 60 is preferred with Slow films comparing to IR 192 code permits.
2. High strength IR 192 for short exposure time even the penetrating strength ate same for low strength( exposure time more).
3. Transverse (shear wave) probes of 2 MHz for stainless steel will give more Hash (grass echo) due to coarse grain structure. You will not able to see indications on screen due to the grass echoes. So we could not do the Ultrasonic Testing of 60 mm thick weld joint with shear wave probe for sure. If you see ASME section 5 article 4 for C.S. weld we can use a plate as Side drilled hole(SDH) cal. block but in stainless steel welds you should make a block with weld and the SDH shall be drilled in weld. For 60 mm thick the dB difference will be more than 6 dB to pick up a hole from S.S plate and S.S. weld.
Twin crystal probes manufactured by RTD are longitudinal wave probes which can penetrates effectively in S.S. weld material. When you make the crystal in angle beam both longitudinal & shear wave will present in steel.
To avoid the confusion between the signals of long & Shear ,twin crystal probes are preferred and these probes having a fixed focal point. you can use that probe for particular Zonal scanning. You have to use at least three probes with different angle and focal spots to cover the complete weld.
Creep wave probes may be used to cover the surface discontinuities.

Regards,
Nilesh Pathare.

[MW:3085] Re: Distortion limit for ASME Section 8 Vessels

You can go upto 20mm( 1%) for the difference between minimum dia and maximum dia you measure.
 
Regarding 0.5 mm localised metal loss, you can exercise engineering judgement. You can apply Uw 35 tolerance on undercut  ( 1mm )for this or  UG 16 plate undertolerance of 0.25 mm.

Yes, All ASTM materials are classed under S-Numbers.

Dear Mr. Tong,
 
Just a small correction, According to QW-420.2 ( S-numbers) , in this case both the materials are S No. 1 Gr. No1 .
If the material is SA106 GR.B then it can be considered as P No1 Gr.1 ( QW-422) , but here the material is ASTM A106 GR.B , hence it is S No.1 Gr.1 ( QW-420.2)  as API 5L GR.B material.
As both are same S No. Gr.No ( S1 Gr.1) materials , there will be no problem for the WPS / PQR from the base material point of view.

Dear Sohaib,
Based on ASME IX, API 5L Gr. B assigned as a S-1 while A 106 Gr. B assigned as a P-1. If procedure qualification testing was done using material assigned an S-Number or S-Number Group Number, the range qualified is limited to materials that are assigned
S-Numbers or S-Numbers Group Numbers (i.e., qualification using a P-Number material qualifies corresponding S-Number materials; qualification using an S-Number material qualifies corresponding S-Number materials but not corresponding P-Number materials; qualification of welders using a P-Number material qualifies them to weld on corresponding S-Number materials and vice versa). For more details you can refer to QW-420.

Dear Sohaib,
 
It will depend on the code you are using is yourexisting procedure has the same code as to the new one you intend to use.
 
Does it cover the thickness and Diameter range
 
As per AWS D 1:1 they come is same group
 
As per ASME Sex IX , they have same Group No. 1 .
 
They have the same strenght 60 Ksi - Tensile strenght .
 
You have to see if any additional Test is required i.e Impact or Corrosion test by the client Spec. as to the previous
 
If all are matching need to check the Electrode Batch or need to contuct the batch test .
 
Let me know if any more information is required or it covers your query .

[MW:3083] Re: Regarding the NDT to be carried out for 60 mm thick austenitic stainless steel plates

Nilesh,
Why would you do these things?
1. No co60 for 69 mm SS?
2. High Strength and Low Strength Ir 192 are same in their pen power.
3. UT of 60 mm SS - well, can you please pass me the proc? I am curious. Twin crystal for what reasons?

[MW:3081] Re: Regarding the NDT to be carried out for 60 mm thick austenitic stainless steel plates

1. Both RT and UT Combination will be best. For surface PT is mandatory.
2. UT we can use Shear wave(SW) for fusion zone, Volumetric can use Angle beam  Longitudinal wave(LW) (Single crystal for higher beam distance and Twin for Near zone)
3. Always better to reconfirm with LW probe wherever SW indication, because shear wave redirect.
4. Using LW for fusion zone probably higer sensitivity (More than code requirment)

Dear Daniel ,

 

If you are looking for spacing between the pipe and the ground , it is stated in the API 1104 for p/l ,

 

If you are looking for spacing between 2 welds  usually it is 3  times diameter , or as per client specification

 

Usually this is defined as if the lenght is less will cause distorsion if the pup piec is very small in lenght and at the same should see their is a min spacing of 2 " between the HAZ of the 2 welds , in case u need to come to a smaller lenght .


 

Thanks

[MW:3068] Percentage of Penetration on fillet weld

Dear All,
 
As I know there are 2 penetrations on welding, full and partial. Only that.
I am wondering since some equipment manufacturer stated in percent in their specification and document regarding their fillet/corner welding penetration, for example 70%. I did not found it in both ASME IX and AWD D1.1. It means that if we talk about partial penetration, no penetration in percent.
 
Does anyone know and advise me about this?
 
Thanks in advance.
 
Regards,
Endri

Hi,

 

 

We have procured a Stainless Steel tank from one of our sub contrators. The thickness of the plate is 6mm. They have done hydrotest also. The tank is shifted to our Project site from the Sub contractors yard. We observed a distortion of 3mm near a Longitudinal seam (Both side of the weld seam).

 

I would like to know the allowable tolerance limit for distortion. Is 3mm acceptable? If it is so please give me the code reference.

 

We observed  a Grinding mark of 0.5 mm depth on 6mm thick Shell. what is the allowable limit for this? Is there any code reference?

 

Your early response in this regard will be highly appreciated.

 

 

Regards

Prabhakar. S

[MW:3066] Re: API 5L GR.B & ASTM A106 GR.B

Dear Mr. Tong,
 
Just a small correction, According to QW-420.2 ( S-numbers) , in this case both the materials are S No. 1 Gr. No1 .
If the material is SA106 GR.B then it can be considered as P No1 Gr.1 ( QW-422) , but here the material is ASTM A106 GR.B , hence it is S No.1 Gr.1 ( QW-420.2)  as API 5L GR.B material.
As both are same S No. Gr.No ( S1 Gr.1) materials , there will be no problem for the WPS / PQR from the base material point of view.

Dear Sohaib,
Based on ASME IX, API 5L Gr. B assigned as a S-1 while A 106 Gr. B assigned as a P-1. If procedure qualification testing was done using material assigned an S-Number or S-Number Group Number, the range qualified is limited to materials that are assigned
S-Numbers or S-Numbers Group Numbers (i.e., qualification using a P-Number material qualifies corresponding S-Number materials; qualification using an S-Number material qualifies corresponding S-Number materials but not corresponding P-Number materials; qualification of welders using a P-Number material qualifies them to weld on corresponding S-Number materials and vice versa). For more details you can refer to QW-420.

Dear Sohaib,
 
It will depend on the code you are using is yourexisting procedure has the same code as to the new one you intend to use.
 
Does it cover the thickness and Diameter range
 
As per AWS D 1:1 they come is same group
 
As per ASME Sex IX , they have same Group No. 1 .
 
They have the same strenght 60 Ksi - Tensile strenght .
 
You have to see if any additional Test is required i.e Impact or Corrosion test by the client Spec. as to the previous
 
If all are matching need to check the Electrode Batch or need to contuct the batch test .
 
Let me know if any more information is required or it covers your query .
 
Thanks

[MW:3065] hydrogen disbonding for SS clad at 530 deg C

Dear all,

I have a vessel SS 347 clad on P4 material. The vessel is to be used
in H2s service at a temperature of 530 deg C. Specification is asking
for autoclave/ H2 disbonding test for weld overlay. what are the
basis to decide for the test? Is it neccessary to do at 530 deg C or
there is any other permutation or combination to do the test at lesser
temp?

If yes please guide
regards,
Amarjit singh
