1 Composition and brief description of chemical plant equipment layout design documents 1.1 Composition of design documents
Chemical plant equipment layout design documents (engineering design) are as follows: 1.1.1 Design document directory;
1.1.2 Partition index diagram;
1.1.3 Equipment layout diagram;
1.1.4 Equipment installation diagram.
Brief description
1.2.1 Design document directory
Only the design document directory to be sent to the construction site is listed, and the intermediate products used for design are not listed in the directory. 1.2.2 Partition index diagram
For jointly arranged devices or independent main items, the device needs to be divided into several zones to draw the pipeline plan. In order to understand the partition situation and facilitate the query, a partition index diagram should be compiled. For smaller devices without partitions, index diagrams may not be drawn.
1.2.3 Equipment Layout Drawing
Engineering design is divided into two stages: basic engineering design stage and detailed engineering design stage. 1.2.3.1 Four versions of equipment layout drawings are prepared in the basic engineering design stage. (1) Preliminary version of equipment layout drawing (referred to as "A version". The equipment layout drawing is prepared based on the preliminary concept formed according to the process flow, layout suggestions and layout regulations of the patent owner and the specific conditions of the project.
(2) Internal review version of equipment layout drawing (referred to as "B version"). (3) User review version of equipment layout drawing (referred to as "C version"). .1.
(4) Confirmation version of equipment layout drawing (referred to as "D version"). 1.2.3.2 Three versions of equipment layout drawings are prepared in the detailed engineering design stage. (1) Research version or detailed version 1 of equipment layout drawing (referred to as "E version"). At the beginning of detailed engineering design, various disciplines carry out work and the equipment layout drawing is improved after multiple researches. This layout has become a final decision and will serve as an important basis for the next step of design and condition proposal. (2) Design version or detailed version 2 equipment layout drawing (referred to as "F" version). This version is used to carry out the design of formal construction drawings. The layout drawing should mark all equipment positioning dimensions and indicate all operating platforms, etc.
(3) Construction version equipment layout drawing (referred to as "G" version). The design version equipment layout drawing is modified according to the requirements of pipeline design and the handling of other issues to become the final construction version equipment layout drawing.
The design scope of the equipment installation drawing refers to some equipment installation drawings that need to be designed by the equipment layout professionals. For example: the baffle frame on the top of the tower, the pad under the cold insulation equipment support, the spring bracket installation drawing of the purchased equipment, etc. · 2·

At the same time, a stress empty sketch should be drawn and submitted to the pipeline mechanics professional for stress calculation and passed to further determine the location and elevation of the relevant equipment. If necessary, the piping of the inlet and outlet of the high-pressure reciprocating pump (empty sketch after the stress calculation is passed) should be submitted to the patent owner or the pump professional for pulse calculation to determine whether the pump inlet and outlet need to be equipped with a shock absorber. b. This version of the equipment layout can only be adjusted slightly (position and elevation) in the subsequent design process. If for some reason, the position or elevation of some equipment needs to be changed significantly, no professional shall make changes without authorization. It must be negotiated by the relevant professionals such as process, system, pipeline design, pipeline mechanics, civil engineering and device layout to reach a consensus, and the changes can only be made after approval by the project manager. c. If the content of this version of the equipment layout drawing is not much modified from the "D" version of the equipment layout drawing, it is not necessary to redraw it.
