A Repair Method for Mouth of Cylinders on Tube Trailers and Its Safety Analysis
摘要
Abstract
Outside threads on mouth of cylinders of tube trailers have been frequently found to be worn se-riously during service.Removing the worn threads and remachining new threads directly may cause the thicknesses of the mouth not to meet the requirements of periodic inspection regulations.Hence a new re-pair method for the mouth of the cylinders is proposed,which removes the original worn threads firstly, then installs rings on the mouths by thermoshrinking and machines external threads on the rings.Safety of the new repair method on a typical cylinder for the tube trailers has been investigated by numerical simu-lation and theoretical analysis.The results show that the new repair method does not affect the service safety of the cylinders.关键词
