Documentation Governance

Public Reference vs. Order-Specific Files

A general catalog or website drawing illustrates standard platform capabilities. However, customized equipment requires project-specific documentation:

  • Public References: Catalogs, standard TDS, typical performance curves.
  • Order-Specific Documents: Approved GA drawings, material mill certificates, hydrostatic test logs, and project-specific FAT records supplied directly with confirmed POs.
Traceability Standard

Revision Control & Compliance Verifications

Certificates for one model or motor grade cannot automatically be assumed to cover an entire family. Compliance depends strictly on configuration:

  • Explosion-Proof: Certified per exact motor make, gas group, and temperature class.
  • Pressure Equipment: Inspected against actual ASME / GB / CE vessel standards.
  • Archival Traceability: Obsolete documents are archived rather than silently updated.
BIM & CAD Models

Need CAD or BIM Families for Plant Layout?

For designers working in BIM (Revit) or AutoCAD environments, verified 2D/3D models and interface blocks are released upon project registration to ensure dimensional fit.

Engineering Integrity Principle

“A downloadable catalog confirms standard capabilities.

When custom materials, non-standard voltages, or severe operating conditions apply, always confirm dimensions and performance with an approved project-specific technical submittal.”
