Problem:

diagramThe pipe fitters have to be able to calculate the length of pipe needed, including the lengths for corners and bends.

What is the length of pipe for the expansion bend shown in the illustration which has a radius (R) of 24 inches, two 10 inch tangents (T), and distance in degrees (D) as shown.

Total L = LA + LB + LC + 2LT

solution

Solution:

Length of the bend:

L= 2 p R · D

  360

 

 

    LA = 2p  24·135

       360        		 = 56.538"
    LB= 2p   24·270

       360     		 = 113.076"
    LB= 2p  24·135

       360     		 = 56.538"

     

56.538 (A) + 113.076 (B) + 56.538 (C)= 226.152 inches

Length of the pipe:

    L + 2T = 226.152 + 20 = 246.152 inches
