static get_class(max_pressure, temperature, material, unit_registry=<pint.registry.UnitRegistry object>)

Finds the minimum allowable flange class per ASME B16.5 for a given flange temperature and tube pressure.

Parameters:

max_pressure (pint.Quantity or Tuple[float, str]) – Maximum pressure within the system as a quantity or tuple of (magnitude, "units")
temperature (pint.Quantity or Tuple[float, str]) – Flange temperature as a quantity or tuple of (magnitude, "units")
material (str) – Flange material (see Flange.available_materials)
unit_registry (pint.UnitRegistry, optional) – Pint unit registry, if output within a particular registry is desired

Returns:

Minimum allowable flange class

Return type:

str

static get_max_pressure(flange_class, temperature, material)

Finds the max allowable pressure for a flange of a given material and class at the desired temperature.

Parameters:

flange_class (str) – Class of the flange to evaluate, e.g. "900"
temperature (pint.Quantity or Tuple[float, str]) – Flange temperature
material (str) – Flange material (see Flange.available_materials)

Returns:

Maximum allowable pressure

Return type:

pint.Quantity

static get_max_temperature(flange_class, pressure, material)
