Abstract

Principle of bend is the existence of shares which stretch at bend exterior and shares which dwindling at bend interior. Pursuant to principle of writer interest to see level accuracy of equation unfold plate if used for the process of pipe bend. Pursuant to literature, there is three formulas or way for bend unfold plate. From third the equation seen which is which most accurate if used for pipe with a few diameter variations and of radius bend. From research got; for pipe with diameter 2,54 and cm of Rb 5,99 cm mount most accurate or lowest mistake is first way that is with method of calculation with neutral area ( normal). With level mistake of mean e = +, 84% For pipe with diameter 3,375 and cm of Rb 7,73 cm mount most accurate or lowest mistake is first way that is with method of calculation with neutral area ( normal). With level mistake of mean e = 0,05 %. For pipe with diameter 4,275 cm, Rb 10,225 cm mount most accurate or lowest mistake is second way that is with method reduction of X constantan with level mistake of mean e = - 0,46%.
