Étape 01 · Source / base

Declare flow, fluid, elevations, and cases.

Objectif

Declare the fluid, design-flow cases, boundary pressures, static elevation difference, and operating scenarios before line sizing or equipment review.

Prochaine décision

Translate the duty into a pipe network and elevation profile.

Questions d’ingénierie

What normal, minimum, maximum, startup, shutdown, and credible transient cases govern?
What are the source and destination levels, boundary pressures, and available hydraulic head?
What fluid density, viscosity, temperature, solids, and material/pressure-class requirements apply?

Contraintes / considérations de conception

Unit conversion can normalize values but does not establish design flow, fluid properties, source/destination boundary conditions, or operating cases.
Surge and transient analysis are outside the current live tool boundary and require a separate system model where applicable.

Outils pour cette étape

Disponible Convertisseur d'Unités Supporting: normalize declared flow, pressure, and length units before hydraulic review. Ouvrir l’outil

Guide d’ingénierie Source & Duty Definition No current ATLAS tool defines the full flow envelope, fluid-property basis, static head, boundary conditions, or transient cases for a pipeline project.

Pipe Network

Map lines, fittings, elevations, and interfaces.

Objectif

Assemble the line, branch, elevation, fitting, valve, material, pressure-class, and layout information needed for separate per-run hydraulic checks.

Prochaine décision

Evaluate major and minor losses for each critical line case.

Questions d’ingénierie

Which line lengths, internal diameters, roughness/materials, fittings, valves, pressure classes, and boundaries are known?
Where are high and low points, air pockets, drains, isolation points, and equipment interfaces?
Which branches and operating modes change flow distribution, balancing, or construction sequence?

Sorties clés

Declared material and pressure-class verification basisengineering review

Contraintes / considérations de conception

PCFforge reviews and edits supported model geometry/topology and material take-offs; it does not solve network hydraulics or verify piping-code compliance.
Pipe Friction evaluates one selected run and cannot model simultaneous multi-branch flow, network balancing, or system curves.
Material, pressure-class, stress, support, constructability, and code checks remain project engineering responsibilities.

Outils pour cette étape

Disponible PCFforge — Atelier de topologie des tuyauteries Conditional: review supported PCF / JSON topology, branch continuity, and material take-offs; not a hydraulic network solution. Ouvrir l’outil Disponible Calculateur de Pertes de Charge en Tuyauterie Supporting: screen an individual pipe run and selected fittings; it does not solve network interactions. Ouvrir l’outil

Guide d’ingénierie Pipe Network No current ATLAS tool solves a full network, balances parallel branches, or validates pressure class, piping code, stress, supports, and constructability.

Friction & Pressure Evaluation

Check loss, fittings, valves, and elevation.

Objectif

Evaluate velocity and pressure loss for a declared single-run case, including friction, selected fittings/valves, and that run’s elevation change.

Prochaine décision

Locate air-management points before finalizing equipment interfaces.

Questions d’ingénierie

Does each critical line diameter keep velocity and single-run losses within project limits?
What friction/minor loss and static elevation contribution apply to each operating case?
How will the line results be assembled into system total dynamic head, a pump system curve, and an operating point?

Contraintes / considérations de conception

Pipe Friction uses Darcy-Weisbach with a Swamee-Jain friction-factor approximation, selected fitting references, and water properties; transitional flow and some fitting-loss regimes are screening-only.
A single-run result is not total dynamic head for a full route, pump system curve, pump operating point, or multi-branch network solution.
The calculator does not model surge, water hammer, pressure-class compliance, structural loads, or transient operation.

Outils pour cette étape

Disponible Calculateur de Pertes de Charge en Tuyauterie Primary: screen velocity, Darcy-Weisbach friction, selected fitting/valve losses, elevation, and outlet pressure for one pipe run. Ouvrir l’outil

Guide d’ingénierie Friction & Pressure Evaluation No current ATLAS tool assembles complete-system total dynamic head, pump curves, network hydraulics, or transient / water-hammer cases.

High Points & Air Management

Screen air-valve geometry and placement.

Objectif

Identify preliminary air-release and vacuum-protection locations from the pipeline profile and operating context.

Prochaine décision

Confirm the equipment and actuation duty at the selected valve interfaces.

Questions d’ingénierie

Where can air collect or sub-atmospheric pressure occur across fill, drain, shutdown, and normal operation?
Which profile high points and changes in grade warrant air-valve review?
What airflow, pressure, capacity, hydraulic grade, and surge checks are required before selecting valves?

Contraintes / considérations de conception

Air Valve Layout provides preliminary placement geometry only; airflow, capacity, pressure/HGL behavior, and transient response require separate engineering verification.
The tool does not size surge protection or establish a final air-valve model or manufacturer.

Outils pour cette étape

Disponible Criblage Géométrique Préliminaire des Ventouses Primary: screen preliminary placement from pipe length or an elevation profile; capacity and transient checks remain separate. Ouvrir l’outil

Contraintes / considérations de conception

Pneumatic Actuator Selector compares user-entered valve demand with entered air and spring torque curves; it does not select a final manufacturer/catalog actuator or validate the valve.
Pipe Friction can recheck only one line case; it does not confirm total system head, pressure class, materials, or operating point.
Final equipment selection requires vendor data, applicable code/design checks, safety factors, and project standards.
