1 Compiled by: Chemical Heating Design Technical Committee Approved by: National Petroleum and Chemical Industry Bureau Implementation date: March 1999-1 National Chemical Engineering Construction Standard Editing Center (formerly the Chemical Industry Ministry's Engineering Standard Editing Center) 1999
This regulation is based on the standard editing task issued by the former Chemical Industry Ministry's Construction Coordination and Standardization Document No. (91) Chemical Engineering Standard No. 21. The reduction work was carried out by the Sixth Design Institute of the Ministry of Chemical Industry on the basis of the "Chemical Plant Heating Duct Implementation Guidelines (70/1-82)\ (hereinafter referred to as the "original regulations\)", and was commissioned by the Ministry to organize the Chemical Heating Design Technical Committee (in 1998, it was renamed the Chemical Heating Design Technical Committee). It has organized many extensive solicitations of opinions from the member units of the Chemical Heating Design Technical Committee (including the national chemical, petrochemical, pharmaceutical, rubber and other ministry and provincial Class A design institutes), revised the draft, and completed the approval of this regulation.
Since the original regulations were promulgated and implemented in 2012, the design field has undergone great changes: the chemical engineering design system and the depth of design documents have been aligned with the requirements of international engineering companies; the design work has been fully AD-based and piece-counting machines have been used in all aspects. Therefore, the original regulations can no longer meet the development requirements under the new situation. It is necessary to formulate a new regulation on the depth of professional design that reflects the current scientific and technological progress, highlights the characteristics of chemical engineering, and has wide applicability and advancement, so as to meet the requirements of the reform of the chemical engineering design system and meet the requirements of domestic and international engineering construction. The main focus of this regulation is to use international standards and the practices of international engineering companies under the premise of complying with the current national standards, and to come up with a set of characteristics of chemical engineering design that is suitable for electronic computer standards. This regulation also proposes: the "example drawings" prepared by computers are intended to facilitate the interpretation and implementation of this regulation. This regulation is revised and compiled by the Chemical Industry Heating and Ventilation Design Technical Committee, and is responsible for the new interpretation of this regulation. All units have opinions or suggestions, and are responsible for notifying the Chemical Industry Heating and Ventilation Design Technical Committee (address: No. 1, Xinhuayuan East Street, Chaoyang District, Beijing, China Global Chemical Engineering Company) by letter. The main drafters of the drafting: Li Kexiao, Su Weigou, Li Shengquan, the staff members participating in the planning: Wan Xueda, Lan Weigang

2 General drawing regulations
2.F Drawing composition and arrangement order
- The drawings of detailed design should be corrected according to the specific situation of the project. 2.1.2 The composition and reduction order of detailed design drawings are generally: drawing catalog, design and construction instructions, equipment list, comprehensive material list, pipeline instrument flow chart, plane diagram, surface diagram, system diagram, machine waste pipeline layout diagram, machine room equipment layout diagram, etc.
2.1.3 When there are different design contents in the same design, the above drawings shall be drawn separately according to heating, ventilation (dust-proof), air conditioning, cooling and other contents, and arranged in order: when one type of design content is more, and the other type of design content is less, the main content is put first, and the secondary content is arranged later. But when the content of the drawing is relatively simple, it is called to put several parts together. Draw on the same drawing to reduce the number of drawing sheets and increase the fullness of the drawing. 2.2 Drawing size and scale
2.2.1 A set of drawings should be drawn on multiple sheets of the same sheet as much as possible (except for tables). Common drawings are A1 solid format. 2,2.2 The format and style of tables should comply with the requirements of the unified regulations of the project. 2.2.3 Use the drawing scale, or Table 2.2.3.

The recommended common height is 75.3.5 and 2.5m
2.4 Drawing layout
2.4.1 When drawing several plane drawings on one drawing, the bottom layer should be at the bottom, and the top layer should be at the bottom. 2.4.2 When drawing pediatric drawings on two drawings, the drawings should be arranged with the half-surface drawing at the bottom, the front drawing at the top, and the system drawing at the top. For cross-section drawings, the system drawing can be drawn on top of the plane drawing. 2.5 Figure Name and Title
2.5.1 Figure name is the name of each sheet, usually marked in the title bar. 2.5.2 Figure number is the name of each drawing, marked at the bottom of the drawing, and a line is drawn under its name: 2.5.3 When there are several illustrations in a drawing, each figure is accompanied by a title. However, when there is no drawing in a sheet, the title may not be shown, and only the figure name is marked in the title bar. 2.5.4 The title can indicate the characteristics of the drawing, such as the drawing method, location, system number, etc. Note: The name of the plane drawing should reflect the main features of each drawing.
2.6 Building outlines
2.G.1 The building outlines in the design should be made according to the architectural drawings, and the room names and numbers, axis dimensions, elevations and dimensions, etc. should be marked with a north needle in the upper right corner of the plan view. 2.6.2 If the plan view needs to be divided into sections due to the construction of the building, the plan view can also be divided into sections. The location and duration of the sections should be consistent with the construction plan. And a schematic diagram of the sections should be drawn. 2.7 Basic drawing method
2.1 The flow chart is made according to Appendix A), not to scale. Attention should be paid to the size, position, height and other relationships of each section. 2.7.2 Plan views, layout drawings, etc. are made with the orthographic projection method. The ventilation ducts and machine room piping are represented by single lines, and the ventilation ducts are drawn with lines.
21.7.3 System diagrams should be made in proportion with the orthographic orthographic projection method. When the orthographic axonometric projection method is used, the angle between the Y-axis and the center line should be 45°. Pipes are shown with single lines. Equipment and hoods are represented by inspection lines or legends. 3
The system representation and direction should be consistent with the plane drawing. 2.8 Drawing marking
2.8.1 Dimension marking
1 In the drawing, the dimension should be marked as "1-56\". You can use the standard code (ear) to mark: You can also use the code to distinguish the elevation marking position, such as ground height, center elevation, pipe bottom elevation, etc. (see the code for the record [3 Elevation refers to the height of the compensation. If the relative height or the relative height of the variable is accurate, it should be explained. 2.8.2 Common pipe properties and types The marking of steel and connecting parts shall refer to Table 2.8.2.
