| Abstract: | The invariablenes condition of circle girth of the join-line end of the main pipe was set up and the join-lines on Y-tee to be ellipse was made certain.The formula to calculate the diameter of branch pipes and ellipse girth was given when the diameter of main pipe is known or reverse to resolve,discussed calculation accuracy.Stress concentration region was made certain after calculating by ANSYS from USA. |
