Strength and dynamic characteristics of mechanically jointed cast-iron water pipelines
Abstract
Elastic and dynamic characteristics of mechanical joints with rubber gaskets and cast-iron pipes are discussed. The main characteristics for pipe failure are the ultimate tension force and the ultimate bending moment. Bolt failure, ultimate gasket friction, the longitudinal elastic constant of gasket, longitudinal periods of pipe due to gasket elasticity, longitudinal periods of pipe due to pipe elasticity, the rotational constant of gasket, period of rotational motion due to gasket, and period of vibration for vertical anti-symmetrical rotational modes of continuous elastic pipes are topics discussed. Some calculations are carried out as examples.
