[MW:12590] CVN Impact test on 304L 2.77mm thick B31.3 piping

Please I need your assistance:-

I have Helium gas Pipeline 304L to be welded by ER308L ,having MDMT at
-269 Degree Centigrade , but the thickness of my Pipe is 2.77mm ,
Which is exempted from the impact requirements from B31.3 Chapter-III,
Table323.2.2 Column B, B-4, Notes -6, Impact test are not required
when maximum obtainable charpy specimen has a width along the notch of
less than 2.5mm.
but my client is not ready to accept that condition/constraint of
B31.3. he needs explanation that How the material thickness(2.5mm)
will bear that MDMT at -269 Degree Centigrad., even Obtainable charpy
specimen is not possible, but How to convince the client the material
will have the properties at that temperature.

Thanks & Regards

[MW:12589] Charpy Impact testing requirement for ASME B31.3 and API SPEC 6A welding application

Hello everyone,

I have a few questions that I need help with please:

1. When developing weld procedures to weld pipe materials like P1
(A106 grade A, B, C, and API 5L X-41, X-46, and X-56) to the same or
any P1 to P1 combination for ASME B31.3 application in an oil and gas
production site for flow lines, I do not need Charpy impact testing
for temperatures of -20F and above right?

2. What if I'm developing welding procedures to join API wellhead
flanges (materials: 4130 welded to the same), is there any minimum
temperature for Charpy impact requirement, in other words, if the
temperature anticipated is going to be -20F and above, is Charpy
impact testing required for this material. If Charpy is required and
it is not at -20F, at what temperature is it required, or do I have to
test for impact/toughness no matter what the temperature is for the
4130 material?

3. What if I'm developing a welding procedure to transition from API
wellhead to ANSI line pipe (material: 4130 to A106 B or any other P1
material), since the design of this joint is based on the weaker
material (A106 grade B or other applicable P1), do I need Charpy
impact testing for -20F and above?

[MW:12588] Algerian Code Requirements

Dear Team,

For one of our project , we have received the comments on cooler drawing as follows

APPLICATION OF "CIRCULAIRE N°2 OF 21st JULY 1993" FOR SHELL AND TUBE SIDES

APPLICATION OF "DECRET EXECUTIF N° 90-245 OF18 AUGUST1990" FOR SHELL SIDE

Any one of you aware of the precautions to be taken care in design with respect to above clause?

Does anyone have extract of the above guidelines?

Thanks & Regards

Re: [MW:12587] Normalizing of dished end

Dear Vishal

First of ASME SEC VIII DIV-1 does not ask for Normalizing of forming part.

In your case, Even Code does not ask for PWHT also.

Even if PWHT is required as per UCL-34, code specify the same with caution notes as below

Postweld heat treatment may be in the carbide-precipitation range for unstabilized austenitic chromium–nickel steels, as well as within the range where a sigma phase may form, and if used indiscriminately could result in material of inferior physical properties and inferior corrosion resistance, which ultimately could result in failure of the vessel.

Hence in your case normalishing is neither recommended nor required.

Dear Experts,
We have Clad plate (SA516 Gr.70 thk 18mm +SA 240 TP 316L thk.4mm). We formed dished end from that plate. normally we do normalizing for the thk above 16mm dish.
so can anyone tell me whether we can normalize the dished endof thk 18+4mm.
If yes then why? and if not, why?

Re: [MW:12585] Normalizing of dished end

Dear Mr. Vishal,

Normalizing 316 may induce phase transformation, reduce corrosion resistance and may sensitise this too. This is a complex problem.

Re: [MW:12584] 3.5% Nickel steel

Hi Pradip / Rajagopal / Nitin,

Thanks for your prompt advise. You are correct I have used E8016-C2 / E8018-C2 with Ø3.2mm (1/8") electrodes.

To share the additional information, the applied preheat was 160°C (continuously maintained by induction coils), max. IPT was 300°C and heat input ranging between 1.5 to 1.8kJ/mm. All mechanical tests / NDE comply with ASME VIII Div 1 with CVN values well above 110J. I have already checked the based material hardness which is below the specification limits < 197HBW. And the re-test of the cap HAZ revealed the nearly the same values ~ 270HV10.

Given the preheat, max. IPT, heat input and compliance of mechanical tests / NDE, I am wondering what could be the likely reason. Any more thoughts or do I need to carry on temper bead technique to get the hardness reduced OR a PWHT for 10.97mm wall thickness?

Thanks & Regards

Hi Mrithyunjay,

If sour service requirements i.e MR-0103, is applicable then the maximum allowable hardness is 22HRC (237HBW or 248HV 10)

Several grades of 3.5% Nickel steel is accepted in ASME Code. If you look carefully in Sec-II ,Pt-A, Grade D has maximum "C" restriction of 0.17%, while for grade E & F this limit is 0.20%. The compositional limits for all other alloying elements are identical for all 3.5% Ni grades.

The default SMAW welding electrode (assuming this was the weld process used) for this grade of 3.5% Nickel steel is E-8016/8018-C2 (Max C -0.12%).When hardness restriction is imposed then welding electrodes could be classified as E-7016/7018-C2L (max C-0.05%).

SFA 5.5 ,Annex-A elaborates the philosophy. If the scenario is such that:-

PWHT is not required as per design code or project specifications

low temperature notch toughness is to be met

hardness requirement is imposed

then low carbon grade E-7016/7018-C2L would be advisable to use in addition to the usual cautions on heat input.

Here the issue of higher hardness is on the HAZ of the capping pass.Essentially if this scatter is isolated, re-evaluate the reading. Otherwise use a lower diameter electrode, typically 1/8" for the final pass and increase the number of runs.This would effectively do better tempering of the capping weld and adjacent HAZ and would help to control the hardness.

While welding 3.5% Nickel steel do not try to exceed the preheat and interpass temperature.Since both the factors tends to reduce the acicularity of 3.5% Nickel weld and HAZ , it could have negative impact on notch toughness values.

Thanks.

[MW:12576] MW: 12563- PWHT of modified P460 NL1 (1.8915) EN 10028-3

Hi David,

Please recall today's discussion on this subject. ASME Sec-IX is yet to assign any P No to this steel. Some authentic references on nominal composition and mechanical properties are available in this attachment.

This material is accepted for design and construction in Sec-VIII, DIV-2 code, through code cases ,i.e CC-2477 (approved June,2005), reapproved as CC-2594 ,Nov-2007. ASME imposed some restrictions on this steel, e.g:-

thickness of plates not to exceed 20 mm (0.79 in)
max copper in the plate -0.20%
Vanadium, 0.10-0.20%
design temperature not to exceed 150 deg F(65 deg C)
PWHT Temperature range-985-1040 deg F(530-560 DegC),Minimum holding time 1/2 hr(30 min) at this temperature.

You may find more details in the code case.

Usually European consumable manufacturers ,ESAB, Bohler Thyssen or Metrode should be in a position to offer the recommended welding products for this steel. As this steel is a HSLA grade, often there may not exactly matching weld metal chemistry. However the consumable supplier definitely will have better idea.

Thanks.

Dear Mr. Azmi,

What is the thickness of the plate material, and are these separate rolled plates or manufactured from coil?

In case of production from coil a minimum of 2 tensile specimens need to be tested for each coil, so in this case 2 specimens would be acceptable. See note 1 chapter 3.2 of SA283.

[MW:12571] DHT requirement of WPS

Dear All,

Regarding DHT (Dehydrogen heat treatment ) of PQR,

I have P4 to P4 PQR with following DHT

Heat treatment temperature :- 350 degree C.

Holding time- 4 Hrs (Time Required by client)

Above DHT requirement as per client specification, but i want use this PQR for different job where no any criteria of DHT requirements, so it is possible to use following DHT cycle

Heat treatment temperature :- 350 degree C.

One tension test coupon shall be taken from each plate-as-rolled (para 11.1.1 of SA20).

Note: plate-as-rolled— the quantity of plate product rolled at one time, either from an individual slab or directly from an ingot.
