Butt Welding Tee Weight Calculator

Advertisement

Approximate weight of a butt welding tee can be calculated based on its header length, branch length, header size, branch size, header wall thickness and branch wall thickness.Please note that actual weight of a tee from a particular manufacturer may vary depending on manufacturing process. Dimensional standards like ASME B16.9 do not provide weights of butt welding fittings.

Weight of a Butt Weld tee as per ASME B16.9 can be calculated as per following formula  :

    \[W=0.02466\times[2Ct_1(OD_1-t_1)+((M-\frac{OD_1}{2})\times(OD_2-t_2)\times{t_2})]\times10^{-3}\times{K}\]

Where :

  1. W = Weight in Kg
  2. t1 = Header wall thickness.
  3. t2 = Branch wall thickness.
  4. OD1 = Header Outside Diameter.
  5. OD2 = Branch Outside Diameter.
  6. C = Run Length Center to end.
  7. M = Branch Length
  8. K = Tee type : Welded : 1, Seamless : 1.363
