Because the pressure vessel is prone to accidents if the internal pressure is too high in the production process, for a chemical enterprise, the production accident will bring the estimated loss of remedial classes. There are many reasons for accidents, most of which occur on pressure vessels. For example, the wear of pressure vessel components and improper operation of personnel will cause pressure leakage or explosion, resulting in safety accidents. Many industries need to know whether the performance of pressure vessels can meet the production standards. In this paper, various quality problems of pressure vessels on the market are analyzed and explored, hoping that some quality problems can be avoided in the production of pressure vessels, so as to reduce the occurrence of accidents and the loss of enterprises from the root. The main method discussed in this paper is to reduce the quality problems of pressure vessels with the help of nondestructive testing technology. Next, this paper introduces the distance and specific application of nondestructive testing technology in detail.展开更多

In the market competition, many enterprises focus on how to occupy a larger share. Too much emphasis on the improvement of production efficiency leads to the serious neglect of the quality of many products, which seriously hinders the long-term development of enterprises. In order to do a good job in product production, the existing quality supervision must be continuously optimized and improved.

The Object Relation Diagram as the object model is employed to describe the object structure of a Web application design and can be translated into the behavior model. A key problem of model checking-based test generation for a Web application is how to construct a set of trap properties that intend to cause the violations of model checking against the behavior model and output of counterexamples used to construct the test sequences. We give an algorithm that derives trap properties from the object model with respect to node and edge coverage criteria.展开更多

High cost, long drilling cycles, and low rate of penetration （ROP） represent critical challenges for offshore drilling operations. The hydraulic pulse generator was specifically designed, based on China offshore drilling technologies and parameters, to overcome problems encountered during offshore drilling. Both laboratory and field tests were conducted to collect the characteristics of the hydraulic pulse generator. The relationships between flow rate and pressure amplitude, pressure loss and pulse frequency were obtained, which can be used to optimize operation parameters for hydraulic pulse jet drilling. Meanwhile a bottom hole assembly （BHA） for pulse jet drilling has been designed, combining the hydraulic pulse generator with the conventional BHA, positive displacement motor, and rotary steerable system （RSS） etc. Furthermore, the hydraulic pulse jet technique has been successfully applied in more than 10 offshore wells in China. The depth of the applied wells ranged from 2,000 m to 4,100 m with drilling bit diameters of 311 mm and 216 mm. The field application results showed that hydraulic pulse jet technique was feasible for various bit types and formations, and that ROP could be significantly increased, by more than 25%.展开更多

We recommend the sequential testing program combining STTs and carclnogenicity assay, the optimal STT batteries, the rules of the sequential discrimination and the preferal choices of STTs tor specific chemical class. For illustrative pmposes the carclnogenicity prediction of several sample chamicals is presented. The results of cost-effectiveness analysis suggest that this program has vast social-economic effectiveness.展开更多
