Abstract: Using the method of mathematical analysis and geometrical theory, the paper introduces the mathematical models about ellipsoidal head and elliptic pipe. The developed equation of the elliptic pipe on ellipsoidal head is derived, and general program for development of elliptic pipe is given. Finally, some examples are given to indicate that the method is simple and convenient in practical use.

Key words: computer application, development, geometrical theory, ellipsoidal head, elliptic pipe, intersection
