Evaluation on the reinforcement designing method of the pipe connected flatly and neatly with the big opening of spherical shell;

There will be great stress concentration appearing nearby the junction of nozzle and shell of pressure vessels with big openings,so reinforcement is absolutely necessary.

Design and industrial application of packed tower using large opening ratio packing support;

Along with the great development of the western region, the urban construction of Chengdu City is bringing about changes day after day.

The stress analysis of the pressurized mixer with two large openings with the same diameters was carried out by use of the finite element method.

An experimental study method to determine the limit load of cylindrical shells with large opening by twice elastic slope method and two tangent method was presented.

The general feature of the large opening with nozzle structure on ellipsoidal head,in which the property of the head is influenced by two interferential boundaries,are investigated in this paper.
