Piping MTO
Template (Excel)

A piping MTO (Material Take-Off) template is a structured spreadsheet for recording every piping component extracted from isometric drawings: pipe cut lengths, fittings (elbow, tee, reducer, cap, cross), flanges (with face rating and bolting), gaskets, studs / nuts, valves, supports, insulation. Per-line grouping with specification and material data per ASME B31.3 (process piping), B31.1 (power), B31.4 (liquid pipelines), or B31.8 (gas transmission). The basis for procurement RFQs, fabrication shop cutting lists, and weld schedule generation.

Yes, this is a blue-ocean workflow with zero software competitors globally. Pathnovo extracts piping MTO data from any isometric format including scanned hand-drawn drawings from the 1980s, PDF exports, ISOGEN outputs, and photographed drawings. AVEVA ERM and Hexagon Smart Materials work only from 3D models; Pathnovo works from 2D isometrics where no 3D model exists. 99.5% contractual accuracy, 48-hour turnaround. See the MTO from isometric workflow.

Excel (.xlsx) primary format. Export variants to CSV (for ERP import), JSON (for API integration), PCF / IDF (ISOGEN / PDS / Intergraph SmartPipe fabrication shop formats). Fabrication shop ERP integration (Larsen & Toubro LFMS, Bentley AutoPIPE, Intergraph SmartPipe, L&T Fabcon) supported via direct format export. See the piping fabrication industry page.

The Code column captures applicable code per line (B31.3 Normal / Category D / Severe Cyclic service, B31.1 for power piping, B31.4 for liquid pipelines, B31.8 for gas transmission, EN 13480 for European process piping). NDE requirements (RT / UT / MT / PT percentage), PWHT requirements (from ASME B31.3 Table 331.1.1), and code-specific material restrictions all flow from the Code designation. For IBR-scoped piping, an additional IBR-scope column flags Chief Inspector of Boilers stamping requirements; see the IBR compliance workflow.

Populated MTO feeds directly into Material Requisition (MR) package assembly; Pathnovo offers this as a managed service via the procurement intelligence pillar. For vendor RFQ workflow, the MTO data groups by specification class (PMS) and material type for efficient vendor packaging. Downstream cost estimation, procurement approval, and vendor PO generation all reference the MTO as the authoritative scope document.

Yes. For revamp projects where existing / modified / new scope coexists on the same isometric, an additional Scope column flags each MTO line as 'existing', 'modified', 'new-installed', or 'demolish'. This prevents over-ordering (procurement team orders only new material) and clarifies fabrication scope (fabrication team knows what is field-welded to existing pipework). Particularly valuable for Indian PSU refinery revamps (IOCL / BPCL / HPCL brownfield projects).

Manual process: open each isometric, identify line number and applicable piping material spec class (PMS), then walk the drawing item by item. For pipe, sum the cut lengths between fittings to get total length per size and grade. For fittings, count each elbow, tee, reducer, cap, and cross by size and end preparation (BW butt-weld, SW socket-weld, TE threaded). For flanges, capture face rating (RF / RTJ / FF), bolt pattern, and gasket type. For valves, gaskets, supports, and insulation, capture per-line totals. Transcribe into the Excel template by line, group by PMS class for procurement packaging. Typical effort: 3 to 6 hours per isometric for a trained piping engineer, longer for scanned or hand-drawn legacy isometrics. Automated alternative: Pathnovo extracts the same piping material take-off Excel sheet from scanned isometrics in 48 hours at 99.5% measured accuracy with no 3D model required. See the MTO from isometric workflow.

The piping MTO (material take-off) is quantity-only, every pipe length, fitting, flange, valve, gasket, support extracted from isometric drawings, used by engineering and procurement to define the scope of material to be purchased and fabricated. The piping BOQ (Bill of Quantities) takes those same items and adds composite rates per unit (supply + fabrication + erection + testing + painting), used by procurement and contracts for tender pricing, contract award, and progress billing. MTO is engineering-owned, BOQ is procurement and contracts-owned. On EPC tenders, contractors price the BOQ to bid; on cost-reimbursable contracts, the BOQ becomes the rate schedule for variation orders. See the piping BOQ template for the BOQ format.
