Performance Assessment of Jumbo Cylinder Pipe Produced by Rotary Expanding Technology TPCO

Abstract:

The rotary expanding is one of the best pipe rolling processes for tube trailer cylinders. The thesis briefly introduced the manufacturing technology features and key equipment of rotary expanding mill of Tianjin Pipe Corporation. The indexes of technical requirements were put forward according to relative cylinder standards and test results were given by a third party. Material performance assessment was conducted by China Standardization Committee on Boilers and Pressure Vessels. The results show that the technical indexes of cylinder pipe including chemical composition, nonmetallic inclusion grade, grain size, microstructure feature, surface quality, mechanical performance and bending test can meet the requirements with an international advanced level.
