Hello
SA790 UNS S32750 is the specification for Super Duplex Pipes & Tubes .

Therfore use of ER2507 filler alloy will help in Ferrite-Austenite balance .

Weld metal producing PREN> 40 is requirement for Corrosion properties for such joints..

I would use the attached brochure for further studies & weld alloy selection.
Hope this helps

[MW:30418] What is the Permissible deviation in pipe to pipe or pipe to elbow fit-up - welding completed joints ?

1 ) What is the Permissible deviation in pipe to pipe or pipe to elbow fit-up for welding?

2) Is there any ASME /ASTM standard which allows the Max. deviation in welding fit and criteria or Tolerance ?

3) If Welding already done with deviation in set-up (Pipe and Elbow O.D Difference), what is the acceptance Criteria as standard or any specifically test need to perform for accepting that condition of welding joining of Pipe and Elbow or Pipe to Pipe of Same Size (deviation because of ovality in Diameter).

Acceptable criteria under standards and Test : Deviation found in welding and fit-up due to ovality in pipe and Elbow, Note : For Welding completed joints.

A Reference Photo is attached for weld Joint, there are many numbers of joint like this, need to convince customer for acceptance.

Check out QW 380/381 of Sec IX as well to take note of the essential variables mentioned therein.

As per Sec. IX, you have to qualify the welders in accordance with QW-301 for joining the base material portion of the cladded pipe. And for welders who will apply the cladded portion of a weld between clad materials, shall be qualified in accordance with QW-381.

If the welder is qualified on P1 material, then the welder is qualified to weld only base material portion of the cladded pipe.

The welders can qualify as per QW-301 & QW-381 separately or alternatively the welders may qualify using cladded test coupon of at least 3/8in. (10mm) thick and of dimension such that a groove weld can be made to join the base material and the corrosion resistant weld metal overlay can be applied to the completed groove weld as per QW-383.

[MW:30416] 16-inch diameter at least two welders shall be used

Dear Experts in Pipeline Welding;

Some Standard states for pipelines greater than 16-inch diameter, at least two welders shall be used, operating simultaneously and in opposite quadrants. But as per international standards or codes nowhere mentioned this requirement for the pipeline welding.

I am interested to know how does above statement requirements profound the integrity of weld joint. What are all the causes if anyhow its not complied?

Regards,

PKB.

Re: [MW:30414] Welding of SA 537 CL. 2

Dears ,

1 - u can use 9018-D1 will give (20J @ -50C) CVN .. also after PWHT hardness will be around 200HV10

2 - u can use 8018-C1 will give (20J @ -60C) CVN ... but Ni is not recommended in wet sour service

so , you can go to 1st choice Mn-Mo elecreod

Best Regards ,
