Re: [MW:31460] Re: Welder qualified 2 7/8 OD, whether he can weld 2” NPS

Dear Mr. Nazeer & All,

Weldolet comes with a Reinforcement which increases Thickness and OD and can it be considered like a Pipe.

Any reference of Code Interpretation with respect to Weldolet for welder qualification.

Thanks & Regards

J.Gerald Jayakumar

Dear Mr.Murali,

Table QW-452.3 specifies the Outside Diameter of pipe, fitting, etc in Inch & mm units. Its not specifying the pipe size in NPS or DN.

Hence OD 73 mm & over qualified welder is qualified to weld 82mm OD .

For better understanding, refer the Table QW-452.3 in mm unit for 82mm OD

Thanks & Regards

Greetings,

I have a weldolet 2" NPS X OD 82 mm, I want to use the welder qualified for 2 7/8 (73 mm) & over.

Query initiated by client that as per ASME SEC IX Table QW 452.3 foot note (b) states that 2 7/8 in. (72mm) O.D. is the equivalent of NPS 2 1/2 (DN 65). In this case the welder client says welder is not qualified for 2 inch NPS.


since the welder qualification essential variable is OD inline with ASME SEC IX, kindly advice.

If any reference kindly share the same.

Thanks 
Murali
