Manual inspection limited in hazardous areas
Restricted access and frequency; "listen-touch-look" cannot catch early bearing and gear defects.

Petrochemical: every shutdown costs millions — protect safety and on-stream factor
High pressure, high temperature, flammable media: one unplanned shutdown costs millions and can escalate into a safety incident. The core is to catch the fault while it is still a seedling: Lean front-loading (Huazhiying Management & Technology) builds graded maintenance and turnaround strategy with RCM/TPM, while DHMS gives pumps, compressors and fans a 30–90 day head start with Ex-rated online monitoring — turning forced outages into planned maintenance.
INDUSTRY PAIN
Three pressures that make petrochemical equipment management high-stakes
×
One failed machine trips the whole unit
Critical-train failures trigger interlocked shutdowns — losses counted by the hour, with safety risk on restart.
≠
One-size-fits-all turnarounds
Fixed-cycle overhauls are expensive; the machines that need watching go unmonitored while healthy ones are repeatedly opened up.
HOW WE SOLVE
Get the maintenance strategy right, and every machine watched
Turn turnarounds from opinion-driven to data-driven
Grade equipment by failure consequence and let RCM decide preventive, predictive or run-to-failure for each — spend the turnaround window where it matters.
- RCM strategy design (graded by safety consequence × downtime cost)
- Turnaround scope & interval optimization
- Spare-parts classification & safety stock (ABC)
- TPM with HSE-integrated equipment ownership
Continuous "health checks" in hazardous areas
Ex-rated wireless vibration/temperature monitoring with AI spectral diagnosis — alerts 30–90 days ahead, complementary to DCS process data: DCS sees process upsets, vibration sees mechanical health.
- Ex-rated sensor selection, installation & compliance
- Online monitoring of critical pumps, compressors, fans
- Diagnosis: bearing wear, misalignment, unbalance, looseness
- Alerts linked to turnaround windows, permits and parts staging
PATH
Start with the highest-consequence trains, then scale
01
Select critical trains
Rank machines by safety consequence and downtime cost; set pilot scope and target savings.
02
Strategy & turnaround optimization
Sort RCM grading, turnaround scope and spares before monitoring scales.
03
Ex-rated pilot
Compliant selection and installation, establish baselines, validate AI alerts against real events.
04
Integrate with turnarounds
Link alerts to windows and permits, build the failure knowledge base, extend plant-wide.

FAQ
Petrochemical: frequently asked
Can wireless condition monitoring be used in hazardous areas?
Yes. Use wireless vibration/temperature sensors with the required Ex certification, installed per hazardous-area regulations in permitted zones. Selection and installation must match the site area classification.
Do wireless sensors add ignition risk?
No — certified low-power sensors eliminate cabling sparks, and cable-free, hot-work-free installation is inherently safer than traditional retrofits. Final selection follows the site area classification and sensor certificates.
How should turnaround intervals be set?
Base them on RCM consequence grading plus live health data: extend intervals for healthy machines, pull forward those with degradation trends — shifting from fixed cycles to condition-based turnarounds.
What is the payback period?
It depends on the cost of one unit shutdown. Industry experience: 6–18 months; for trains where one shutdown costs millions, a single validated alert can cover the whole investment.
