Knowledge & Tools
Look up, check, calculate – online
The Plant Engineering Infobase and Questions from practice are free; the pipe calculators (support span, weight, thermal expansion, pressure drop) can also be used without login. You use the Catalog Checker (1 catalog free) and the Piping Spec Calculator with a customer account.
Knowledge
Freely accessible for reference – for design, studies and education.
Plant Engineering Infobase
Standards, flow diagrams, plant identification, disciplines, piping specs, CAD practice – with cross-references and built-in tools.
Questions from practice
254 questions from training and support, with answers – P&ID, Plant 3D, piping specs, AutoCAD, Navisworks, ReCap.
Work aids
Quick references, checklists and piping spec info sheet – free with a customer account
Plant identification
Pipe marking to DIN 2403 as print template, KKS, AKS, RDS-PP – simulation for teaching
Piping specs and catalogs
Preliminary sizing of a piping spec, output as a Plant 3D catalog and check – the most recently calculated spec is available for selection in all calculators.
Piping Spec Calculator
Preliminary sizing of wall thicknesses to EN 13480-3, AD 2000, DIN 2413 (hydraulics) or ASME B31.3 – carbon steel, stainless steel, nickel, copper (EN 1057), hygienic/dairy pipe (DIN 11850/11851), GRP, plastic – calculation free of charge; as a Plant 3D catalog with a Catalog Checker package (0.1 catalog credit per family = €13–17 net depending on package).
Catalog Checker
Check and correct a Plant 3D catalog, export it as Excel for the Autodesk Catalog Builder, add components (0.1 catalog credit per family, €13–17 net depending on package).
Connection Assistant
Check and extend end types and pipe connections – EndCodesConfig.xml and DefaultConnectorsConfig.xml, free of charge
Unit converter DN · Class · material
DN ↔ NPS, schedule ↔ wall thickness, PN ↔ Class, material ↔ ASTM – for reading third-party piping specs and specifications.
Pipe calculations
Preliminary sizing for design – guide values are marked; PCF files from Plant 3D can be imported.
Support Span Calculator
Permissible support spans – with values taken over from the Piping Spec Calculator.
Pipe weight
Pipe, contents, insulation per meter – load per support for operation and pressure test
Thermal expansion
Estimate length change, expansion joint pre-tension, L/Z/U bends
Pipe sizing & pressure drop
Flow rate → nominal size, pressure drop including fittings and valves
