Pipeline pressure and flow setpoints

Identifies substantive pipeline pressure, flow, operating-limit, and control-setpoint records. Topic phrases are retained for discovery; enforcement requires a populated pressure or flow value, and high confidence also requires a pipeline segment, station, valve, control tag, or other live asset reference.

Type: regex
Engine: boost_regex
Confidence: medium
Confidence justification: Medium confidence requires a populated engineering value rather than a pipeline topic alone. High confidence adds a specific station, segment, valve, or control reference, reducing matches on safety standards and engineering lessons.
Detection quality: Topic false positive
Jurisdictions: global
Regulations: GDPR
Data categories: security
Scope: wide
Risk rating: 9
Platform compatibility: Purview: Compatible, GCP DLP: Compatible, Macie: Compatible, Zscaler: Compatible, Palo Alto: Degraded, Netskope: Unsupported

Should match

pipeline pressure setpoint — Low-tier probe - topic without a populated engineering value
Pipeline pressure setpoint: normal 6.8 MPa and high limit 7.2 MPa — Medium-tier probe - populated pressure values without a live asset reference
Pipeline pressure and flow setpoints for compressor station CS-04 and pipeline segment PL-17: PT-204 high trip 7.2 MPa, flow 620 m3/h — High-tier probe - populated values with station, segment, and control-tag detail

Should not match

unrelated generic text without domain phrases — No relevant topic phrases present
placeholder value 12345 — Random text should not match topic-specific regex
pipeline flow — Generic word pair from old broad template should not match
The public pipeline safety guide explains maximum allowable operating pressure. — Public guidance without populated operating values
Training example: pipeline pressure setpoint for compressor station CS-04 is 7.2 MPa — Explicit training content must not enforce

Known false positives

Pipeline standards and engineering courses discuss MAOP, pressure relief, compressor stations, and flow limits without exposing current operating values. Mitigation: Keep topic-only matches discovery-only and require a populated pressure or flow value for enforcement.
Worked examples can include realistic station names, segment IDs, control tags, and pressure values. Mitigation: Reject explicit template, demo, tutorial, sample-data, and training-example framing from enforcing tiers.
