## Design Codes for Pressure Piping

Design engineers need to ensure code compliance with readable, auditable calculation reports. You can use Maple Flow to implement ASME B31 pipe codes for pressure piping, as well as their international equivalents (such as AS4041, BS 010230 and DNVGL-ST-F101).

• Maximum Allowable Pressure in a Mitred Elbow
• Reinforcement of an Extruded Outlet Header or Fitting
• Required Pressure Design Wall Thickness for Bends (AS4041)
• ASME B31.3 Processing Piping - Required Pressure Design Wall Thickness for Bends

## Pressure Losses and Flow Rates in Pipelines

Design engineers use Maple Flow to determine head and flowrates in pipes and pipe networks. These calculations often need strong iterative solvers. You can collect these equations together in an unstructured form, and solve them with Maple Flows math functions. You can also implement standard semi-theoretical equations for predicting gas flow through long pipelines, such as the Weymouth or IGT equations.

• Two-Phase Pressure Drop of Gas and Liquid Flowing in a Pipe
• Flow Rate of Natural Gas Through Pipelines
• Pressure Loss and Flow Rates in Pipelines

## Pipeline Economics

Economic planning influences engineering design. Maple Flow can be used to determine economic pipe sizes and operating conditions

• Economic Pipe Sizing
• Deriving a Least Cost Pipe Diameter Equation

## Liquid and Gas Orifice Meters

Engineers use Maple Flow to size valves and orifices or to calculate the flow through orifice meters.

• Large Diameter Orifice Flow Meter For Gases
• Small Diameter Orifice Flow Meter for Liquids

## Thermodynamics and Heat Transfer

Maple Flow offers a full, computable database of transport and thermodynamic properties for liquids and gases. This database can be linked to your calculations, so that properties are maintained when two intendent states (such as temperature and pressure, or temperature and entropy) change.

• Physical Properties of Natural Gas
• Expansion Loop for Thermal Expansion of Pipes

## Strength and Deflection of Buried Pipes

Maple Flow can be used to implement the equations that describe the deflection of rigid or flexible pipes, buried in soil. The modified Iowa formula is the accepted method of calculating the vertical deflection of buried flexible pipes. The strength of rigid pipes (such as those made of concrete or steel) is determined by Marston theory.

Both approaches can be implemented with Maple Flow, providing auditable, readable calculation reports.
