welding api 5l x52 with x60

[QA/QC]

Dear master 

i have a approved wps for welding api 5l x52  pipeline and i want to weld a anchor flange x60 is the wps cover it or we should requlaify it again 

[Ramesh]

As per API 1104 , 2013 edn, Clause 5.4.2.2 , you can use the same WPS without requalification. I presume your flange and fittings are having same SMYS ( Specified Minimum Yield Strength)  and similar CEq

 

Requalification is required only when the base metal welding involves less than X42 or greater than X65. In your case this is not applicable.

 

Make sure, Your WPS have mentioned : Qualified Base material X42 Through  X60.

 

            Keeping future qualification purpose, it’s better to qualify PQR with X65 material which many customers accept for all lower grades’ base metal qualification.

Thanks and Regards

API 1104 permits to weld the below but check your specifications as some specifications like shell DEP do not permit to weld high thickness above 25mm and pipe to fittings using Cellulosic electrode which commonly used for Pipeline welding.

in my case i have also a wps for piping api 5lx52 to a105 -  can i use it to weld it with a694 f 60

May I know what was the consumable used in your X52 WPS ?

Thanks and Regards

It is a normal practice in Pipeline to use low tensile electrode for the Root and hence you can use the WPS for welding X52 to A694 F60 as the requirement is the minimum Tensile strength as below. Check the PQR that 95% of UTS 67ksi (X52) is achieved.

For Piping, no issue.

Its mean im in safe area to weld x52 with a694 f60 with thé same WPS 

Électrode 6010 with 7018 or er70-s6 with 7018

In addition to Consumable aspects as above by Mr. Jerald, Few points  to support that Requalification is NOT required to weld with  ASTM A694, F60

 

1.    As per Clause 5.3.2.2 of API 1104, other material product specifications can also grouped,  i.e ASTM A694, F60 has same SMYS of 415 Mpa as well as API X60

 

2.    The Base metal falls under second grouping i.e X42 to X60 ( 290 to 415 Mpa – SMYS) which you have already qualified by X52 material (360 Mpa) from the same grouping.   

Thanks and Regards
