Re: [MW:30828] Tube to Tube sheet welding, Orbital welding parameters for header box

What's the method for preheating?  You have to ensure whole thickness is covered for preheating to reduce the cooling rate.

I am having isues with hardness on the heat affected zone. The criteria to meet is 248 Hv10 (vickers). Especially at the Haz zone iam getting 300 vickers.

Anyone have experience in tube to tube sheet welding can offer some suggestions that will be great.

My best results were in 0.095 wall thickness where HAZ readings were close to 250 still failed becauseit was marginally over. 0.065, 0.83 failed with HAZ hardness averaging at 300.

Re: [MW:30824] Tube to Tube sheet welding, Orbital welding parameters for header box

Doesent increasing heat input accelerate cooling, provided i cant control the quick loosing of temperature from the interpass. I was thinking about increasing roatational speed and simultaneously reducing amperages, which somewhat keeps the cooling rate down.

[MW:30822] Two Base metal different thicknesses on same PQR

Hello dear colleagues, 

I hope this email finds you well

Code: ASME IX

In order to qualify a WPS, one client proposed to me to weld and qualify only one PQR test plate composed of 2 plates with 2 different thicknesses (12,5 x 9,5mm).

Does this proposal make any sense, regarding obtaining more open qualifications in terms of Base Metal thickness, I mean, 1.5 to 25mm?

My belief is that must be welded 2 test plates 9,5 x 9,5mm and 12,5 x 12,5mm. 

Is my interpretation of 2 different plates, too rigorous and narrow-minded?

Thanks in advance.

[MW:30817] Re: X22 CRMOV12-1 +QT2

X-20 is a nasty steel, just ideas about welding welding consumables, methods would not help. If you have mastered the welding methods and techniques for Grade-91 steel, then handling X-20 would be easy, although this steel is always problematic.

I had handled this steel 30+ years ago for a major power plant project. If you're interested , feel to contact me offline or in LinkedIn.

Hi,

  S275JR is unlisted material in AWS D1.1, so you have to make a new WPS.

hello friends,

I have a WPS with ref code AWS D 1.1 for A36 can I use the same for welding S275JR as well? 

I would like to know if there is any code prohibition for this? Even though the materials are almost the same except for a higher yield strength for S275.

Best regards

Re: [MW:30809] How to handle gasoline pipeline spill/leakage activity keeping contemporary HSE practices

Hello, 

I would like to brief you some details of pilferage of LPG pipeline in which I have worked in earlier pipeline project.. 

1) The location is near to road crossing  and heavy leakage of LPG is found at center of Canal crossing. The LPG is getting leaked with high pressure.
2) The spreading of LPG was checked with LEL meter and it was found that LPG Gas vapours are profusely gushing out from the canal bed and the vapour concentration was spreading around
300meter all around the location. Immediately the area was barricaded and following action taken with help of local administration and following activities has been performed:

a) The Road is closed 1 KM on both side to restrict entry of vehicular traffic and general public.
b) Electric Power supply of the area was shutdown completely.
c) Evacuation of nearby villagers in 1 KM surrounding was carried out by local administration.
d) Fire tenders mobilized to site.
e) High Pressure leak clamps and Non Sparking Tools along with PPE's has been mobilized at site.
f) Venting of LPG started at HIPS and SV-12 to reduce the pipeline pressure in the section between to SV stations ..
g) The district authority clamped prohibitory orders under section 144 of Cr PC in the 2 km radius to avoid people approach the accident 
spot. Villagers were told to move to safer places and not to light lamps and match boxes at any circumstances

h) After confirming the LEL the excavation was done and pipe was exposed at pilferage location. and observed that Tapping was done at pipeline by fixing of clamp and providing around 1.5 meter long pipe with 2 isolation valves.
i) As the gas vapors are still available in open trench therefor The Clamp and assembly used for tapping was removed.
j) Leak clamp was installed at leak location, to restrict any entrapment of GAS vapors.
k)  Regular monitoring of GAS vapors with LEL meter was checked around the clock
l) Regular spraying of water being done to displace entraps vapors from soil.
m) As the LEL reading are not in line therefore the further operation for replacement of pup piece in place of damaged section was suspended till the LEL reading will reduced to safer limit to start
welding and cutting operation.
n) After getting the LEL reading in safe limits, cold cutting of pipe started. The pipe piece was removed from the laid pipeline section.
o) The LEL was checked and it was found that LPG vapours are being available at trench, the LPG vapour traces from pipeline was observed. so urther operation was suspended for the day.
p) After taking LEL reading again the clearance was given to start welding.
q) 2 meter hydro tested pup piece welded in the section. NDT of pipe bevels with UT/DPT done. NDT of weld joint was carried out in presence of TPI. After clearance of NDT, joint coating was done. 

r) Backfilling completed after peel test of coating done.

[MW:30806] API 650/RT interpretaiton

Dear Experts,

Can anybody help me by providing API 650 interpretation for radiography.

What I understood is only welderwise RT required for vertical joint for each welders/operators first 3 mtr vertical joints, all other RT requirements are irrespective of welder or welding operator.

I could not understand the interpretation of clause "8.1.2.6 An equal number of spot radiographs shall be taken from the work of each welder or welding operator in
proportion to the length of joints welded."

Thanks in advance.

Manoj

Απ: [MW:30801] Heat input and cooling

The issue is complex. 

Higher heat input  with high sink (large and thick work) will result in high cooling rate which will result to high hardness if no adequate preheat

Yes. More heat input will be cooled slowly depending on somany condition where as less heat input will be cooled faster .

Dear all
I am confused about the following statement. Can anyone tell me the reason.

High heat input causes slow cooling and low heat input causes fast cooling.

I understand that cooling is a function of temperature differences between the metal and ambulance system. If high heat input causes high temperature then temperature differential should be higher than low heat input.
Can any one tell me the reason.
