Dear Friends,

 

What is the difference between 1 inch welding and 1 inch dia welding?

 

1 inch dia = 1* 3.14 = 3.14 inch. Is this right.

 

One full welding on a 42'' pipe is 42'' dia welding...is it right.

 

Thank you,

 

Regards,

 

Sabir

The term Inch Dia OR Dia Inch is used for the quantity of welding for the piping fabrication.
 
1 inch dia/Dia inch = Size of the joint X No. of the joints.

inch dia parameter is used for ease of  estimating man hours , costing etc. where as inch may mean inch thick of  materials .
inch  dia  means  phi x  dia of  pipe in nominal size in FPS system but again the costing , man hours , consumable estimation is also depends on the wall thickness ( schedule 160. XXS   etc).
