8/18/2019 Inch Dia Calculation

1/1

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 iping !pool , !ay it

has a pipe of "# ($% m long), with flange on one end and elbow on another. &ou are pro'iding a branch connection of %# on it.

elding inchdia in it is

*otal joints of "# in it + $(pipe with flange) $(pipe with elbow) $ (it is optional - if 

a pipe purchased is of m length then you need to weld pipe to pipe to gain $%m

length spool, but if pipe purchased is of $%m length then it is not re/uired).

so inch dia + "01 + $%.

 2ow for branch connection of %# on mother pipe of "#, you need to pro'ide a

weldolet, which will add one joint of %# size. so inch dia + %0$ + %

!o *otal inch dia in'ol'ed in fabrication of that spool + $% % + $"inchdia.
