degree pipe fitting direct  2  elbow no middle pipe

rolling pipe elbow degree calculation 

first check 90 degree elbow fitting 

12 × 38.1 = 457.2  × 2 = 914.4 

pipe center to center dimension 800 

not fitted 90 degree elbow 

check the 45 degree elbow  

12 × 15.7 = 188.4 × 2 = 376.8 

this is not fitted 45 degree elbow 

check the another degree

i take the 100 mm triangle dimension  and calculate 

 √( 800^2 + 100^2 = 806.2 mm travel length 

how to find travel pipe elbow degree | rolling pipe elbow degree calculation 

 tan-1( 800 ÷ 100 = 82.8 degree 

 calculate the 82.8 degree elbow center 

82.8 ÷ 2 = 41.4 degree

tan( 41.4 ) × 1.5 × 25.4 = 33.5896

12 × 33.5896 = 403.1 × 2 = 806.2  mm travel length 

calculation complete 

elbow degree,   82.8 degree

pipe face to face dimension 

100 + 806.2 = 906.2 mm  running pipe dimension 

now calculation complete
