[MW:14166] Change in Manufacturer for Plate Requires MPQT in Line pipe

Dear Experts,
 
         One of the Manufacturer initially rolled the line pipe (API 5L) for the line item x ( dia 44" x 16.9 mm) with Voset Alpine plates, for the same manufacturer conducted Manufacturer Procedure Qualification test (MPQT) and the result found satisfactory. As there was not enough quantity of plates to complete the line item Manufacturer informed the line item x will be rolled after procuring the plates. Mean time manufacturer rolled for other line items of the same P.O with different sizes. Manufacturer received the plates from Sumitomo instead of Voest alpine to complete the partially rolled line item x ( dia 44" x 16.9 mm). In this case whether manufacturer shall conduct MPQT once again for the Sumitomo Plates for the line item x ( dia 44" x 16.9 mm) or elsae we shall conduct test unit only instead of MPQT. Please clear my doubt.

[MW:14165] RE: 14154] PWHT OF P 91 ALLOY STEEL MATERIAL.

Subject: [MW:14158] RE: 14154] PWHT OF P 91 ALLOY STEEL MATERIAL.


Stress corrosion cracking has been noted in as welded 91 material when
it has been wetted. The concern is that the welds may have dew
formation, or in some way be exposed to water. 91 in the as welded
condition should be held indoors in temperature and/ humidity controlled
conditions. An alternative is to keep in indoor storage but with the
welded material maintained at a temperature above the expected dew point
(by electric resistance pads most likely). The seven day thing is bit
arbitrary and my personal take is that it is just to make sure that PWHT
is performed in a timely manner. My experience with large amounts of
welded 91 is that there has been no cracking even after extended time (a
couple of months) in the as welded condition but we hold all as welded
91 in climate controlled conditions. I have not seen any empirical
evidence that 7 days, 14 days, or 30 days makes any difference provided
storage conditions are appropriate.



Note that function of the preheating and post heating you are doing is
to prevent hydrogen assisted cracking. The preheat and post heat allow
hydrogen to diffuse out of the material. Entirely different worry than
SCC in the presence of water.



Also note that any water; pure or otherwise has been demonstrated to
allow SCC in as welded 91 and it only needs be a film of water.

Dear All,



We are going to do P91 piping fabrication, as per client
specification the stroage time after welding is limited to maximum 7
days for PWHT. Is there any problem if it delays 10 days when we are
following preheating procedure for welding as mentioned below:



Preheat at 200 degree C. Min. 300 degree C. Max.

Inter pass temperature 250 to 300 degree C.

Cooling 20 to 80 degree C. after wleding

Post heating (extended heating) after cooling 300 degree C.

for four hours or 400 degree C. for three hours.



Thanks in advance for your response.\



Manoj.

Good afternoon.
As per section V we have to go for procedure qualification before the start the radiography in job.
Is there any group range for dia and thickness for the procedure qualification or we have to go for all individual dia and thickness.
Kindly advise and also give reference code for the same.

[MW:14157] weld hard spots on castings

Dear Experts,

Can anybody  clarify me with literature.

We have typical problem like this:

We are making small cosmetic weld on castings - P1 materials ( WCC and LCC)
Process used is SMAW. we use welding electrode E 7018-1.
We use a preheat of 45-95 Deg C.Interpass being 300 deg C.PWHT is done @ 610 deg C.
We had already demonstrated PQR with the parameters like electrode,current, preheat, interpass,and PWHT, the same are being excercised in the production weld also.
Once after PWHT when we check hardness using portable (Equo-tip) hardness tester we find some welded spots shows high hardness which exceeds NACE  requirements (237 HB).
We are facing similar high hard spot on material ASTM A 487- 4C material also.

Re: [MW:14152] regarding- thickness range for LTCS piping material for WPS

hello darshan
its Ajay here
 
your thickness limit will be 7.11 to 14.22
this is as per ASME sec IX......bcouse for LTCS u have to do the impact test............in dis case ur limit will me in lower side is 7.11 but limited to 2T in higher side........
jus go thorugh ASME sec IX chapter 4 clause no QW-403.6

QW-403.6

The minimum base metal thickness qualified

is the thickness of the test coupon

T or 58 in. (16 mm),

whichever is less. However, where

T is less than 14 in.

(6 mm), the minimum thickness qualified is

12T. This variable

does not apply when a WPS is qualified with a PWHT

above the upper transformation temperature or when an

austenitic or P-No. 10H material is solution annealed after

welding.

ASME Sec VIII Div 1 does not state tolerance on vessel straightness which is customer specific. However, most customers specify the straightnee as 1mm per meter with max limit of 19mm for vertical vessels.

Kindly suggest the appropriate gaskets to avoid frequent leakages from

Re: [MW:14131] 13% Mn steel Welding

Hi Harish
 
For welding 13-14% Mn Steels you can use Austenitic manganese steel : E18-8-6 type SMAW electrodes or FCAW wires.
This electrode contains 0.1-0.4%C, 18%Cr, 8%Ni and 6% Mn. The weld deposits are work hardenable type. As deposited hardness=200HB, after workhardening= 47 HRC.
Welding has to be done very slowly with controlled interpass temp. of 150 degrees Celcius max.
Mostly the component is immersed in a water bath tub during welding to maintain the interpass temp.
Also weld with low heat input, lower current settings. Weld stringer and short beads.
 
If you tell me the application i can give you the solution as i have welded plenty of Hadfield steels !
 
Regards

Re: [MW:14129] Re: regarding- thickness range for LTCS piping material for WPS

As per ASME Sec.IX QW451.1 thickness of test coupon is 1.5mm to mm means the thickness qualified limit is 1.5mm (Minimum) and 2T(Maximum).
In your case, If you use 7.11mm thickness specimen for PQR then the Thickness Qualified limit will be 1.5mm to 14.22mm.

Subject: [MW:14128] Re: regarding- thickness range for LTCS piping material for WPS

what is your design code?
As per ASME it will be T-2T, however for piping (B31.3) this range can
be used if PTC's are provided for the thickness ranges as specified in
Table 323.3.1, else it will be T to T+6mm

Best regards
