TMIN (an abbreviation for "minimum thickness") is an open source python package designed to help engineers determine if corroded process piping in refineries and pertrochemical plants are safe and API-compliant — in seconds.
Many oil and gas companies are faced with maintaining thousands of miles of 100+ year old piping networks supporting multi-million dollar/year processing operations. There is rarely a simple solution to immediately shutdown a process pipe - as these shutdowns more often than not impact other units and cost companies millions in time and resources.
TMIN can be used as a conservative and rapid engineering support tool for assessing piping inspection data and determine how close the pipe is to its end of service life.
pip install tminfrom tmin import PIPE
# Create pipe instance
pipe = PIPE(
pressure=50, # Design pressure (psi)
nps=2, # Nominal pipe size (inches)
schedule=40, # Pipe schedule
pressure_class=150, # Pressure class
metallurgy="Intermediate/Low CS",
yield_stress=23333 # Yield stress (psi)
)
# Analyze measured thickness
results = pipe.analyze(
measured_thickness=0.060, # Measured thickness (inches)
year_inspected=2023 # Optional: inspection year
)
print(f"Flag: {results['flag']}")
print(f"Status: {results['status']}")
print(f"Governing thickness: {results['governing_thickness']:.4f} inches")Run TMIN in a container:
