Platform · P&IDs

Upload a P&ID. Get a structured, connected engineering knowledge graph.

Armeta's contextualization engine reads any legacy PDF P&ID — scanned paper, rasterized CAD plots, flat image exports, faded reproductions from decades-old archives — and turns it into structured, connected engineering data. Cross-drawing connectivity is resolved automatically, so off-page connectors are reconciled across your entire drawing set into a facility-wide engineering knowledge graph.

What Armeta extracts

Every entity on the P&ID, identified and connected.

The P&ID is the master schematic of your process. Armeta extracts every operationally meaningful entity on the sheet — not just text, but the engineering objects that text represents.

Equipment items

Vessels, columns, exchangers, drums, pumps, compressors, packages — every tagged equipment item identified, classified, and linked to its source region.

Piping lines

Every line on every sheet, with line number, size, spec, service, and routing parsed from the line label and resolved against your numbering convention.

Instruments

Transmitters, indicators, switches, controllers, analyzers — both inline and panel-mounted — with their loop tags and signal connections.

Control valves

Control valves, on/off valves, motorized valves, and their actuators, identified by tag and resolved to their controlling instrument loop.

Safety devices

Pressure relief valves, rupture disks, flame arrestors, and emergency isolation valves — captured with their setpoints and the systems they protect.

Tags & annotations

Every alphanumeric tag, callout, note, and revision cloud, captured with its position so engineers can audit extractions against the source drawing.

Off-page connectors

Every off-sheet reference identified, paired across the drawing set, and resolved into directional connections in the facility graph.

Title-block metadata

Drawing number, revision, sheet, project, area, unit — pulled directly from the title block and used as the indexing key for every other extraction.

Cross-drawing connectivity

50 to 200+ sheets per unit, reconciled into one facility graph.

A single process unit lives across dozens to hundreds of P&ID sheets. The engineering reality of the unit is the connectivity between those sheets— not the contents of any one drawing in isolation.

Armeta resolves cross-sheet connectivity automatically. Off-page connectors are identified, paired, and reconciled into a directional graph that spans the full drawing set.

Stage 01

Per-sheet extraction

Symbols, tags, and lines parsed sheet by sheet.

Each sheet is processed independently. Equipment, lines, instruments, and off-page connectors are identified at the symbol level, with every extraction tied back to a specific region on the source drawing.

Stage 02

Connector identification

Off-page connectors picked up wherever they live.

Off-page connectors are identified regardless of style: triangle, arrow, circle, or vendor-specific. Each connector carries its referenced drawing, sheet, and line number into the graph so the next step has unambiguous handles to reconcile against.

Stage 03

Cross-sheet reconciliation

50 to 200+ sheets resolved into one connected graph.

Connectors are matched across the full drawing set. A line leaving sheet 12 toward sheet 34 is paired with the matching connector on sheet 34. Conflicts, dangling references, and revision mismatches are surfaced as discrepancies rather than silently dropped.

Stage 04

Facility graph assembly

One queryable map of every line, every tag, every connection.

The reconciled set becomes a single, navigable engineering knowledge graph. Equipment tags trace back to source drawings, lines trace end-to-end through every sheet they touch, and the whole facility is addressable as structured data.

Cross-document context

How P&ID data contextualizes against isometrics and line lists.

The P&ID is the anchor document, but it is not the only record. Armeta resolves entities across documents so the same line, the same tag, and the same equipment item carry one identity across drawings and data tables.

Stage 01

Line-number resolution

The line on the P&ID is the line on the isometric.

Line numbers are parsed using your numbering convention and used as the primary entity key across documents. The same line on a P&ID, an isometric, and a line list resolves to a single record in the graph.

Stage 02

Equipment-tag matching

Tag identity, not tag substring.

Equipment tags are normalized and matched against isometric title-block references and line list equipment columns. Soft matches (formatting variants, leading zeros, hyphens) are reconciled; hard mismatches are flagged for review rather than guessed.

Stage 03

Attribute reconciliation

Where the documents disagree, you find out.

Sizes, specs, services, and operating conditions are compared across documents. A line tagged 6" on the P&ID and 8" on the line list is surfaced as a discrepancy, not silently averaged. The graph keeps both values with their source documents.

Legacy PDF handling

The drawings your archive actually contains.

Armeta does not require smart PDFs. The vast majority of the global P&ID archive exists as flat images: scanned paper, rasterized CAD plots, and faded reproductions. No embedded metadata, no selectable text, no vector layers. The contextualization engine reads them all.

If your team is working from the documents you actually have rather than an idealized smart-PDF set, Armeta meets you where the archive lives.

Scanned paper drawings

Decades-old paper P&IDs, scanned at any resolution, with smudges, fold lines, and stamp marks — read as-is.

Rasterized CAD plots

Flat-image PDF exports from legacy CAD systems with no embedded metadata, no selectable text, and no vector layer.

Degraded reproductions

Photocopies of photocopies, faded blueprints, low-contrast microfilm scans — the documents your archive actually contains.

Mixed-vintage archives

Sets that span symbol conventions across decades and authoring tools. Armeta adapts to your conventions sheet by sheet.

Accuracy and validation

Accuracy you can put in a contract.

Every P&ID extraction Armeta delivers is validated by our engineering team before it reaches you. Accuracy metrics on your own drawings are produced as part of the initial document audit — our ten-document free assessment that establishes baseline performance before any paid engagement.

Engineer-reviewed extraction

Every extracted graph is reviewed by an Armeta engineer against the source drawing before delivery. Not raw model output.

Source-linked traceability

Every entity in the graph is linked back to the exact region on the source sheet it was extracted from. Auditable, click-through, defensible.

Statistical accuracy sampling

Equipment-, line-, and instrument-level sampling against ground truth on every engagement. Accuracy metrics produced on your own drawings.

Revision-delta review

Change reports between revisions are reviewed against both source drawings before MOC packages are produced.

Deployment

Your drawings. Your environment. Your terms.

Three deployment modes, chosen to match the security and governance constraints your engineering records actually live under.

Mode 01

Cloud

Fastest time to value

Armeta-hosted, isolated per customer. Your engineering documents and extracted data remain segregated from every other customer environment.

  • Isolated tenant per customer
  • Data residency US, EU, or customer-designated region
  • Production-ready in days, not months
Mode 02

On-premise

Your network, your perimeter

Armeta's contextualization engine runs inside your network. Your documents never leave your environment. Deployed with customers today under data residency and air-gap requirements.

  • Documents never leave the customer network
  • Air-gap-compatible deployment
  • Suitable for classified processes and strict residency policies
Mode 03

Private cloud

Managed inside your tenant

Armeta-managed deployment inside your own cloud tenant. Cloud operational model, customer-controlled perimeter.

  • Customer-controlled cloud perimeter
  • Managed service lifecycle
  • Fits existing cloud governance frameworks
Your P&IDs, your data

Start with ten of your own P&IDs.

Before any procurement conversation, see Armeta run on your actual P&IDs — sheet by sheet, with cross-drawing connectivity resolved. Not sample data. Not a generic demo. Your drawings, contextualized, delivered as a structured report in one engagement.
