Isometric Drawing

Procedure of making isometric Drawing: 
1. Created on isometric paper. 
2. "Shop Isometric" should be prior precedence than "field isometric". 
3. Each line must be able to show a clear information. 
4. Drawing should be clear and easy to read. 
5. Piping each path can be made when necessary in some isometric drawing. 
6. Pipe line routes should be made thicker from other lines. 
7. If there is any doubt in how the image, then information, in order to review prior to construction . 
8. Isometric drawing generally does not scale, but may make seproporsional. 
9. Each reference image should be indicated. 
10. Direction of image needs to be listed as well as the number isometric. 
11. Type of pipe support should be clear. 
12. Description repairs (revision) should be clear also the last. 
13. General description must be clear and specific. 

Isometric drawings should show this: 
1. Title of the pipe line. 
2. Channel pipe, which is the number, size, classification, direction 
flow and to repair. 
3. Dimensions or the size of each material. 
4. Coordinates, orientation, ELEVATION, each piping path and equipment. 
5. Reference image a connection or a connection piping path. 
6. Size gasket or gasket. 
7. Symbols, specifications, codes, standards must be clear and 
engineering division has been set previously. 
8. Forms of employment. 
9. If there is a change in the form of work or limit the work must be clearly indicated. 
10. Coordinates, orientation, ELEVATION and type of pipe support. 
11. Nozzle and pressure on the pressure valve savety. 
12. Coordinates, orientation, and type of instrumentasinya ELEVATION. 
13. Form of connection, such as with pengelasan, thread, weld and thread, and so forth. 
14. Not need to brace the branch connection is used. 
15. Slope to a vertical direction with the "V" and horizontal with code "H". 
16. Signs of curvature and curvature broken. 
17. O'let or communicator as weldolet, and sockolet - other. 
18. Number of the spool at a desired image isometric. 
19. Is stress relief or not. 
20. Type of insulation. 
21. Boiler piping codes such as pressure, temperature and service. 
22. Other references such as LDT (Designation table line), P & ID, image vendors, a special reference case required field. 

After the isometric drawing is declared finished after checking through some phase or examination, then He is ready to send this picture as a guide to the field of employment in the field, but must remain checking against a P & ID, LTD, models and other reference.
