Research On Accuracy Control Of Ship Pipe Based On Modern Shipbuilding Mode

The hull accuracy controlling is an important technique in the process of the ship building.With shipbuilding accuracy control,it can decrease the fix ratio for hull erection,increase efficiency,and shorten the period.Under the modern shipbuilding mode of hull-outfitting-painting integration with the section outfitting technique and the accuracy ship building technique developing,it is significant to further develop ship building technique,that taking the technique of hull accuracy control technology to outfitting,and piping system accuracy control,it can be guaranteed that the error of the part size of outfitting can be in the permitted scope with implement of piping accuracy control.Increase the manufacturing of outfitting and installation quality.With the coordinate product,the impact of the outfitting in the hull erection period can be reduced,and it can create conditions for hull-outfitting-painting integration,and it has significant meaning for labor productivity,reducing ship building period and enhancing production capacity.According to the process rule of ship accuracy control system combine with advanced ship yard piping accuracy system management,this paper has investigated the ship piping accuracy control of modern shipbuilding mode.For the first,this paper investigated the problem in the modern ship building for piping accuracy,analyzed the reason of the problem for piping accuracy,and suggested the uniform idea for the hull accuracy control and outfitting accuracy control..It has investigated the implement of the piping system accuracy control,built up organization system for piping system accuracy control,formulated the standards and key point for the process of pipe,pipe element accuracy control,and piping system installation accuracy control.It has investigated the technology of piping system accuracy,and taken the investigation for carrying technique.At the last,it has verified the significance of the implement for the piping system accuracy,with the practical application and effect from the target ship piping system accuracy control.
