Description
Technical Field
The invention relates to a three-dimensional processing design method for a pipeline.
Background
At present, in the fields of petroleum, chemical industry and the like, pipeline drawings provided by detailed design parties are further processed and designed, and the realization of fine construction is very common. The tooling design generally includes: adding on-site welding information, single pipe numbers, flange node numbers, modifying pipe blanking length and the like, summarizing materials according to the processed and designed drawing, and compiling a construction material list. The key for improving the quality and efficiency of the three-dimensional processing design of the pipeline is to accurately and quickly compile processing design drawings and material lists.
The traditional pipeline processing design mainly comprises the following two methods:
1. the method comprises the following steps: based on a two-dimensional drawing provided by a detailed designer, adding machining design information into computer-aided drawing software (such as AtuoCAD) manually by personnel, and modifying the blanking length of a pipe to generate a pipeline mapping diagram; the piping design is completed by manually gathering the material into a spreadsheet (e.g., Mircosoft excel).
2. The second method comprises the following steps: based on an intermediate format file (such as IDF/PCF) provided by a detailed designer, partial machining design information is manually added into two-dimensional design software (such as Smartplant spooolgen) by a person, a pipeline axonometric diagram and a basic data table are derived according to a set graph format, and then the basic data table is manually summarized into an electronic table to finish the pipeline machining design.
The above pipe processing design method mainly has the following problems:
1. the traditional pipeline processing design method is based on a two-dimensional drawing or a middle file provided by a detailed design party, and the files only contain pipeline information and do not contain three-dimensional environment information around the pipeline. The addition of processing design information such as the position of a welding spot on the spot and the like completely depends on the space imagination of designers, and the design quality is greatly influenced by the experience of the designers.
2. The processing design axonometric drawing and the data sheet derived by the traditional pipeline processing design method are completely or partially compiled by hand according to different compiling methods, and different file styles are caused by different expression modes of different personnel, so that the standardization of project files is not facilitated, and the identification difficulty is brought to field production personnel.
3. The processing design information generated by the traditional pipeline processing design method is transmitted in a file form, and data is difficult to be efficiently utilized by other production links.
4. The traditional pipeline processing design method is low in efficiency and high in error rate.
