--- pcr_id: pcr.metal-products-machinery-and-equipment.basic-metals.line-pipe-of-a-kind-used-for-oil-or-gas-pipelines-seamless-of-steel language: en-US status: candidate sync_with: pcr.zh-CN.md --- # Seamless steel line pipe for oil or gas pipelines ## 1. Scope and Applicability This candidate covers seamless steel pipe supplied for oil or gas pipeline service after manufacturing acceptance. Declare carbon/non-alloy, low-alloy or other specified steel grade individually; no grade, composition, diameter, thickness or treatment range is assumed. It excludes longitudinal/spiral welded pipe, drilling casing/tubing/drill pipe, noncircular profiles, fittings, bends fabricated after pipe manufacture and installed pipeline construction/use. Upstream metallic iron, steelmaking and casting are linked supplier burdens, not duplicated pipe-forming methods. ## 2.

Reference Flow | Field | Value | | --- | --- | | What | Seamless steel line pipe for oil or gas pipelines | | How much | 1 kg | | How well | oil/gas linepipe application; specification and edition; product specification level; steel grade and heat chemistry; outside diameter, wall thickness and length; seamless forming route; hot/cold finishing; delivery heat-treatment condition; sour-service requirements; inspection and hydrotest acceptance; surface/coating system and coating mass; end preparation; site, period and feed starting state | | How long or cycle | One supply at manufacturing gate; no pipeline service life is claimed | | reference_flow_link | `final_product` | | Field | Value | | --- | --- | | Reference amount | 1 | | Reference product flow | Accepted seamless steel line pipe | | Reference flow property | Mass `93a60a56-a3c8-11da-a746-0800200b9a66` | | Reference unit group | Units of mass `93a60a57-a4c8-11da-a746-0800200c9a66` | | Reference unit | kg | | Required qualifiers | oil/gas linepipe application; specification and edition; product specification level; steel grade and heat chemistry; outside diameter, wall thickness and length; seamless forming route; hot/cold finishing; delivery heat-treatment condition; sour-service requirements; inspection and hydrotest acceptance; surface/coating system and coating mass; end preparation; site, period and feed starting state | Declare all qualifiers in dataset metadata. D is the positive accepted net mass for the matched reporting period, with adherent coating included only when it is part of the declared delivered product. Separate steel-body and coating masses. Packaging, rejected lots and free test water are excluded. ## 4. Measurement and Unit Rules | rule_id | Applies to | Required property | Required unit | Rule | | --- | --- | --- | --- | --- | | reference_mass | final_product | Mass | kg | cp_final_product measures D; each exchange normalizes its attributable period amount by D. | | conversion | all exchanges | Row-specific property | kg; m3; kWh; MJ | Retain raw units and conversion evidence: 1 kWh = 3.6 MJ. Fuel volume needs measured net calorific value at declared temperature/pressure; wet wastes need solids and metal fraction. | | balance | production | Mass | kg | Retain separate gross masses of received steel, accepted steel body, scrap, wet solids, water and opening/closing work in progress; do not add contained-iron mass to gross steel mass. Close the elemental iron balance on one contained-Fe basis: measured Fe in external feed plus opening work in progress = measured Fe in accepted steel body, external scrap, scale, sludge and effluent plus closing work in progress and every other measured Fe release. Derive each term from its own measured gross mass and Fe assay; use matched concentration and volume for effluent. Retain carbon and each actual alloy-element oxidation, release, retained mass and chemical-reaction records as separate elemental balances. Account for oxygen uptake, water content and actual reaction products; never assume pure iron, common composition, a fixed conversion or an invented yield. Cancel internal rework; retain its repeated energy and chemistry. Close water makeup + opening storage = external transfer + discharge + evaporation + product carryover + closing storage; close acid/chemical active-component stock, reaction, carryover and waste balances with measured uncertainty. | ## 5.

Allocation and Co-product Handling | rule_id | Applies to | Rule | source_ids | | --- | --- | --- | --- | | allocation_hierarchy | joint operations | Prefer subdivision; otherwise substantiate physical causality. Economic allocation is fallback with consistent period/currency/prices and sensitivity; retain unallocated totals. Do not use pipe mass alone as a furnace allocation driver unless it explains grade, heat cycle and loading differences. | `ef-allocation-2021` | | allocation_rework | rework and residue | Retain all repeated processing energy and material for reworked/retested lots. Cancel internal transfer quantities; measure external scrap, scale and sludge separately and apply actual treatment once.

output reference = 1 kg. Reconcile material stocks and cancel internal transfers before calculation. | cp_final_product; row-specific cp | per 1 kg | | | physical_balance | site | Retain separate gross masses of received steel, accepted steel body, scrap, wet solids, water and opening/closing work in progress; do not add contained-iron mass to gross steel mass. Close the elemental iron balance on one contained-Fe basis: measured Fe in external feed plus opening work in progress = measured Fe in accepted steel body, external scrap, scale, sludge and effluent plus closing work in progress and every other measured Fe release. Derive each term from its own measured gross mass and Fe assay; use matched concentration and volume for effluent. Retain carbon and each actual alloy-element oxidation, release, retained mass and chemical-reaction records as separate elemental balances. Account for oxygen uptake, water content and actual reaction products; never assume pure iron, common composition, a fixed conversion or an invented yield. Cancel internal rework; retain its repeated energy and chemistry. Close water makeup + opening storage = external transfer + discharge + evaporation + product carryover + closing storage; close acid/chemical active-component stock, reaction, carryover and waste balances with measured uncertainty. | Steel/iron assays; water meters; acid concentration; stocks; waste records | Closure residual with measurement uncertainty; no invented tolerance | | | energy_conversion | utilities | Metered kWh × 3.6 = MJ; fuel mass × measured NCV = MJ.
