Abstract
The calculating model and calculating software for insulating risers were researched in detail on two kinds of cast steels ZG0Cr13Ni4Mo and ZG230-450 in order to guide the technological design of insulating risers. By means of various research methods such as mathematical analysis, numerical calculation, casting experiment and nondestructive testing, the characteristics and applicability of mathematical analytic methods using Cubic Equation, Perimetrischen Quotient or Q-number were compared and analyzed. It was found that the Cubic Equation method is suitably used as the calculating model for insulating risers. In addition, the corresponding calculating software is developed. The research methods and results can be reference for the technological design and calculation of insulating risers used for other kinds of cast steels.
