Dear raga,

Inch dia in welding is nothing but the multiplication of size of joint x no of joints (of that size) which you need to weld during fabrication. Consider a Piping Spool , Say it has a pipe of 4" (12 m long), with flange on one end and elbow on another. You are providing a branch connection of 2" on it.

Welding inchdia in it is:

Total joints of 4" in it = 1(pipe with flange) + 1(pipe with elbow) + 1 (it is optional - if a pipe purchased is of 6m length then you need to weld pipe to pipe to gain 12m length spool, but if pipe purchased is of 12m length then it is not required).

so inch dia = 4*3 = 12.

Now for branch connection of 2" on mother pipe of 4", you need to provide a weldolet, which will add one joint of 2" size. so inchdia = 2*1 = 2

So Total inchdia involved in fabrication of that spool = 12 + 2 = 14inchdia.

I hope, it will clear ur doubt.

regards,
rakesh
