Planning chemical and process plants with AutoCAD Plant 3D
New plant, extension or modification in a chemical park? Many media, many materials and dense regulations call for a clean project template and checked piping specs. We set up AutoCAD Plant 3D for this and support your team in the project.
With us you will find solutions for your tasks.
Typical plants
- Chemical and petrochemical plants with many media and pressure ratings
- Raw material processing and metallurgy plants
- Multi-purpose and pilot plants that are frequently modified
- Tank and filling plants, utilities in the chemical park
Typical planning tasks
- Set up projectTag formats, title blocks, layers and lists to your company standard – defined once, the same in every project.
- Compare the P&ID with 3DLines, valves and instruments from AutoCAD P&ID go into the 3D model; the comparison shows what is still missing.
- Piping specs per mediumMaterial, pressure rating and gasket per medium in one piping spec – from steel pipe to enamelled or PTFE-linedPTFE – Polytetrafluoroethylene Fluoroplastic, very resistant to chemicals; in piping, used mainly for gaskets and linings. Background and sources › lines.
- Isometrics for fabricationFabrication isometrics with bill of materials, cut list and weld list directly from the model.

Piping specs and catalogs
These ASEING piping catalogs suit chemical plants in particular – steel, stainless steel, enamel and lined pipes, plastic and valves:
- Carbon steel – pipes & fittings – 2 catalogs
- Stainless steel – pipes & fittings – 5 catalogs
- Enamel / DIN 2873 – 3 catalogs
- Plastic – pipes & fittings – 9 catalogs
- Valves (DIN EN) – 12 catalogs
All catalogs with contents: ASEING Piping Catalogs. Your own piping spec? Size it in the Piping Spec Calculator – preliminary sizing, not a piping design. Existing catalogs are checked by the Catalog Checker.

Questions from practice in training and support
- Same nominal size, different material – new size or new part family? To the practice question
- The manufacturer gives no pressure rating – what goes in the catalog? To the practice question
- Error on sealing face or pressure rating at the vessel nozzle To the practice question
- After updating the piping spec the material is missing To the practice question
All questions: Practice questions in the Infobase.

Frequently asked questions
Is AutoCAD Plant 3D suitable for chemical plants?
Yes. AutoCAD Plant 3D includes AutoCAD P&ID for the P&ID and plans piping by piping spec in 3D. Isometrics, orthos and bills of materials are generated from the model. For chemical plants, the project template and piping specs matter most.
Can you model enamelled or PTFE-lined lines?
Yes. There are dedicated ASEING piping catalogs for enamel to DIN 2873 and for PTFE- and PFA-lined pipes.
Who defines the piping specs?
You or your client define the piping specs. We implement them in AutoCAD Plant 3D and check the catalogs. The Piping Spec Calculator helps with preliminary sizing – it does not replace a piping design.

Terms, background and sources 9 terms on this page
Brief explanations for reference. They do not replace the standard or code itself.
- R&I – Piping and instrumentation diagram
Flow diagram showing all pipes, valves, equipment and instrumentation of a plant (P&ID, Piping and Instrumentation Diagram).
Symbols and drawing rules: DIN EN ISO 10628-1 and -2. Identification letters for instrumentation: DIN EN 62424 or ISA-5.1.
- PTFE – Polytetrafluoroethylene
Fluoroplastic, very resistant to chemicals; in piping, used mainly for gaskets and linings.
- DIN – German Institute for Standardization
“DIN” before a number means that the standard is published in Germany by the German Institute for Standardization.
DIN was founded in 1917 as the Standards Committee of German Industry. If “DIN EN” or “DIN EN ISO” precedes the number, a European or international standard has been adopted unchanged as a German standard.
- EN – European Standard
European Standard, developed by CEN (general) or CENELEC (electrical engineering).
Every member country must adopt an EN unchanged as a national standard – in Germany as “DIN EN …”. Conflicting national standards are withdrawn.
- ASME – American Society of Mechanical Engineers
US engineering society. Its codes for piping, flanges and pipe dimensions apply in many plants worldwide.
ASME was founded in 1880. Well-known codes: B31.3 (process piping), B16.5 (flanges), B36.10M and B36.19M (pipe dimensions).
- B31.3 – ASME B31.3 Process Piping
US code for process piping: materials, design, fabrication and testing of piping in chemical and process plants.
- ISO – International Organization for Standardization
“ISO” before a number denotes a worldwide standard of the International Organization for Standardization in Geneva.
ISO was founded in 1947. Its members are the national standards bodies; for Germany, this is DIN.
- PN – Nominal pressure rating
Designation for the pressure rating of flanges and valves (Pressure Nominal), e.g. PN 16. It corresponds roughly to the allowable pressure in bar at room temperature; at higher temperatures, less is allowed.
Specified in DIN EN 1333. The pressure-temperature ratings for each material are given in the component standards, e.g. DIN EN 1092-1 for steel flanges.
- IEC – International Electrotechnical Commission
International Electrotechnical Commission in Geneva: worldwide standards for electrical engineering and for instrumentation and control.
IEC was founded in 1906. IEC standards adopted in Europe are called “EN IEC …” or “EN 6xxxx”.
