1 Overview
These regulations apply to the drawing of equipment layout drawings in chemical plants. 2 General regulations
2.0.1 Drawing size
Generally, A1 is used, and it is not advisable to lengthen or widen it. Other drawing sizes may also be used in special cases. 2.0.2 Scale
1:100 is commonly used, and 1:200 or 1:50 may also be used, depending on the density of the equipment layout of the device. However, for large devices (or main items), the same scale must be used when drawing the equipment layout drawings in sections. 2.0.3 Dimension units
The elevations and coordinates marked in the equipment layout drawings are in meters, with three digits after the decimal point, up to millimeters. The remaining dimensions are all in millimeters, with only numbers and no units. When other units are used to mark dimensions, the units should be indicated. 2.0.4 Drawing Name
The drawing name in the title bar is generally divided into two lines, with "×××× Equipment Layout Drawing" written on the upper line and "EL×××.××× Plane" or "×-× Section" written on the lower line. 2.0.5 Numbering
Each equipment layout drawing should be numbered separately. The equipment layout drawings of the same main item shall not use one number, and the numbering method of the number of sheets and the total number of sheets shall be added.
3 Design regulations to be followed
3.0.1 For the line width and font regulations, see HG20519.28~92. 3.0.2 For the legends used in the equipment and pipeline layout drawings, see HG20519.34-92. 29
3.0.3 For the commonly used abbreviations of pipelines, see HG20519.27-92. 4 Drawing arrangement and view requirements
4.0.1 Equipment layout drawings generally only draw plan views. For more complex devices or devices with multi-story buildings and structures, when the plan view is not clear, a partial view or a partial view can be drawn. The partial view symbols are specified to be represented by AA, BB, and uppercase English letters.
4.0.2 Equipment layout drawings are generally drawn with jointly arranged devices or independent main items as units, and the boundary area is represented by thick double-dotted lines. Mark the coordinates outside the boundary area, with the lower left corner of the boundary area as the reference point. The coordinates of the reference point are N, E (or N, W), as shown in the figure below. At the same time, note the coordinates X and Y values equivalent to those on the general plan. N Xiang
4.0.3 A direction mark consistent with the design north direction of the general plan should be drawn in the upper right corner of the drawing with the plan. 4.0.4 For multi-story buildings or structures, the equipment layout plan of each floor should be drawn layer by layer. When drawing the factory floor plan on the same drawing, it should start from the lowest floor plan, and arrange the layers from bottom to top or from left to right on the drawing, and indicate "EL×××, ×××Apple surface\, etc." below the drawing.. In general, only one plan is drawn for each floor. When there is a local operating table, only the equipment under the operating table can be drawn on the plan, and the local operating table and the equipment above it can be drawn in a separate local plan. If it does not affect the clarity of the drawing, it can also be drawn in an overlapping manner, and the equipment under the operating table is drawn with a dotted line..6 When a device passes through a multi-story building or structure, the plane position of the equipment must be drawn on each floor plan, and the set number must be marked. The strict surface drawing of each floor is a top view cut from the horizontal part of the floor bottom surface of the previous floor. 5 Drawing content and scale mark
5..1 Mark the axis number and axis size of the building and structure according to the professional construction drawings, and mark the indoor and outdoor floor elevations.
5.0.2 Draw doors and windows according to the positions shown in the architectural drawings , walls, columns, stairs, operating platforms (note the top elevation of the platform), water dischargers, hanging rails, railings, mounting holes, pipe racks, pipe trenches (note the bottom elevation of the trench), open trenches (note the bottom elevation of the trench), water spill slopes, cofferdam roads, passages, etc.
5.0.3 If there are control rooms, power distribution rooms, living and auxiliary rooms in the device, their respective names should be written. 5..4 Use dotted lines to indicate reserved maintenance areas (such as heat exchanger extraction tube bundles), draw them in proportion, and do not mark the size, such as: ex xxxars
5.0.5 Non-standard equipment can be simplified appropriately, and its appearance can be drawn, including the attached operating table, ladder and bracket (note the bracket drawing number). For equipment without pipe opening orientation diagram, its characteristic pipe opening (such as manhole) should be drawn, and the azimuth angle should be indicated. For horizontal equipment, its characteristic pipe opening should be drawn or the fixed end support should be marked. For dynamic equipment, only the foundation can be drawn to indicate the position of the characteristic pipe opening and the driving machine, as shown in the following figure:TUBN Pipeline pipe opening

5.0.6 Mark the equipment position number above the center line of the equipment, and mark the elevation of the support point (such as POSEL××××) or the elevation of the main shaft center line (such as EL××××) below. 5.0.7 The type and size of the equipment can be based on the relevant data and dimensions given in the equipment data sheet provided by the process professional. If the equipment data sheet does not provide relevant data and dimensions, the actual shape should be simply drawn. 5.0.8 Planar positioning dimensions of equipment
5.0.8.1 The plane positioning dimensions of the equipment should be marked as far as possible based on the axis of the building or structure or the center line of the column of the pipe rack or pipe gallery: the coordinate system can also be used to mark the positioning dimensions. 5.0.8.2 For horizontal containers and heat exchangers, the centerline of the equipment and the centerline of the pipe opening (such as manholes, pipe connection openings) are used as the reference line, see the figure in 5.0.5.
5.0.8.3 For vertical reactors, towers, tanks, tanks and heat exchangers, the centerline of the equipment is used as the reference line, see the figure in 5.0.5. 5.0.8.4 For centrifugal pumps, compressors, blowers and steam turbines, the centerline and the centerline of the outlet pipe are used as the reference line. 5.0.8.5 For reciprocating pumps and piston compressors, the centerline of the cylinder and the centerline of the crankshaft (or motor shaft) are used as the reference line. 5.0.8.6 For plate heat exchangers, the centerline and the end face of a certain outlet flange are used as the reference line. 5.0.8.7 For auxiliary equipment that is directly related to the main equipment, such as reboilers, ejectors, reflux condensers, etc., they should be marked with the centerline of the main equipment as the reference line. 5.0.9 Equipment elevation
5.0.9.1 Horizontal heat exchangers, tanks and troughs are indicated by the centerline elevation (ELX×××). 5.0.9.2 Vertical and plate heat exchangers are indicated by the support point elevation (POSEL××××). 5.0.9.3 Reactors, towers and vertical tanks and troughs are indicated by the support point elevation (POSEL×××X×). 5.0.9.4 Pumps and compressors are indicated by the main shaft centerline elevation (EI.X×××) or the bottom surface elevation of the chassis (i.e. the top surface elevation of the foundation) (POS EL×× XX).
5.0.9.5 For pipe galleries and pipe racks, the elevation of the top of the rack is indicated (TOSEL×××X). 5.0.10 When there are more than three pieces of equipment with the same position number, the appearance of the first and last two pieces of equipment can be indicated on the plan view, and only the foundation of the middle piece can be drawn, or it can be indicated by a double-dotted square. 6 Notes in the drawing
