Condition Monitoring Service

Get to know your coil condition – Exclusive for steam cracker operators

Our Condition Monitoring Service enables steam cracker operators to keep a precise overview of the radiant coil condition.

No more guessing about remaining service life – we deliver accurate, data-driven insights that help ensure furnace integrity, maintain operational safety, and plan tube replacement with confidence, extending their lifetime wherever possible.

Condition Monitoring Tool

Sensor-Based Condition Tracking Along the Entire Tube

Using sensors to detect carburization & nitridation over the full tube lengthwise & crosswise to measure Consumed Life of radiant tubes.

We achieve this with our non-destructive Condition Monitoring Tool – CMT

Equipped with four highly accurate sensors
Capable of scanning the tube lengthwise and crosswise
Able to crawl up and down one tube in just five minutes
Measures the difference in condition between tube sections – full picture!
It currently works with standard materials (25-35 & 35-45)

How it works

Transforming Measurements into Maintenance Strategy

The key to transform raw sensor readings into reliable, actionable insights lies in exceptional calibration. At S+C, we’ve built an extensive database of ex-service samples over many years. This forms the solid foundation for accurately calibrated sensors tailored to each alloy. Our deep knowledge of alloy ageing behavior enables us to deliver highly precise, alloy-specific measurement solutions.

Planned shutdown

When planning an on-site inspection, we coordinate closely with the steam cracker operation to develop a detailed inspection plan based on technical drawings. This ensures everything is prepared for a smooth and efficient process when the day of measurement arrives.

Inspection at the furnace

Our approach is holistic. During the furnace evaluation, we not only conduct precise measurements using our Coil Condition Monitoring Tool, but we also perform a thorough visual inspection of the furnace.

For an inspection on site we plan ahead with the steam cracker operation and provide all the necessary inspection plan based on the technical drawings. When the day comes for the actual measurement, we have everything set up for smooth operation.

S+C Data Analysis

After the on-site work is completed, we carefully analyze and interpret the data. Our reports provide more than just numbers; they offer valuable insights, clear interpretations, and well-founded recommendations for the next steps to take.

Result and support

We provide a detailed report that translates complex measurements into clear, actionable recommendations. Our experts are available to support you in implementing these findings, whether it’s planning tube replacements, adjusting operations, or improving future maintenance.

The Result

The results of our findings will be delivered in form of a report. Or the results could be presented in person, if preferred
