1. Appearance Inspection
Surface Integrity: Inspect the titanium coil's exterior weekly for scratches, dents, or cracks, focusing on stress concentration areas such as welds and bends to prevent pitting corrosion caused by the accumulation of corrosive media.
Connection Tightness: Check welds and flanges for looseness. Use a leak detector or soapy water to test for minor leaks to prevent performance degradation caused by media leakage.
2. Performance Monitoring
Heat Exchange Efficiency: Compare the inlet and outlet fluid temperature difference using an infrared thermometer and calculate the heat transfer coefficient based on flow meter data. If the efficiency drops by more than 10%, investigate for scaling or foreign matter buildup.
Pressure Stability: Monitor system operating pressure fluctuations. Abnormal increases may indicate internal blockage and require prompt shutdown and inspection.

1. Physical Cleaning
Daily Dust Removal: Gently wipe the coils along their length every two weeks with a soft microfiber cloth to avoid scratching the oxide layer with hard tools. Internal dust can be removed with a low-pressure blower (≤0.2 MPa).
Treatment of Stubborn Stains: For adherent dust, scrub with a soft brush in warm water (≤50°C) along the grain. Avoid scrubbing against the grain to prevent surface scratches.
2. Chemical Cleaning
Neutral Solution Cleaning: Use a dedicated titanium cleaning agent with a pH of 6-8, dilute it in a 1:20 ratio, soak for 10 minutes, and wipe with absorbent cotton.
Deep Decontamination Solution:
Baking Soda + White Vinegar: For oily stains or mild oxidation, mix a 1:3 ratio of baking soda and white vinegar and soak for 30 minutes. Scrub gently with a soft brush, then rinse with clean water.
Acetone Cleaning: For laboratory use only, for localized scrubbing of delicate components, wear a gas mask and operate in a fume hood. Taboo List: Strictly prohibit the use of chlorine-containing bleach, steel wool, or sandpaper to prevent damage to the TiO₂ passivation film and accelerated corrosion.

1. Environmental Protection
Media Isolation: Prevent titanium coils from contact with chloride-containing media such as hydrochloric acid and seawater. If contact is unavoidable, apply a polytetrafluoroethylene (PTFE) protective layer.
Temperature and Humidity Control: Maintain a relative humidity of ≤60% and a temperature between 5°C and 40°C in the storage environment to prevent electrochemical corrosion caused by condensation.
2. Tool Selection
Cleaning Tool Restrictions: Metal brushes or steel wool with a hardness greater than 200 HV are prohibited. Nylon brushes or suede cloths are recommended.
Interface Protection: When cleaning flange connections, seal the pipe openings with dedicated plugs to prevent impurities from entering the system.
3. Cleaning Frequency Optimization
Normal Environments: Perform a comprehensive cleaning once a month and record the heat exchange efficiency curve.
Severely Polluted Environments (such as chemical plants): Perform a cleaning every two weeks and add inline filtration to extend the maintenance interval.

1. Storage Environment Requirements
Basic Conditions: Store in a constant temperature and humidity warehouse (25±5°C, humidity ≤50%), with moisture-proof mats laid on the floor, at least 50 cm from the wall.
Precision Component Protection: Sensitive components such as pressure sensors and diaphragms must be individually sealed in a nitrogen cabinet with an oxygen content ≤5 ppm.
2. Upgraded Protective Measures
Seal Management: Inspect O-rings and gaskets for aging quarterly, and replace immediately if their elasticity decreases by >30%.
Installation Specifications: Pipeline horizontality deviation ≤0.5 mm/m, and bracket spacing no more than 1.5 m to prevent vibration-induced weld fatigue cracking.

1. Internal Scaling Treatment
Chemical Soaking Method: Soak narrow areas such as pressure taps in trichloroethylene (analytical grade) for 24 hours, then use an ultrasonic cleaner to remove calcium carbonate scale.
Mechanical Clearing: Use a 0.8 mm φ titanium alloy wire cleaner. Steel tools are strictly prohibited to prevent galvanic corrosion.
2. Regular Professional Maintenance
Annual Overhaul: Certified engineers disassemble the coils and inspect their straightness using a laser interferometer. Straightening and repair are performed if deviation exceeds 1mm.
Parameter Calibration: Temperature sensors and pressure transmitters are calibrated every six months to ensure the error between displayed and actual values ​​is ≤0.5%.

Through systematic daily management, standardized cleaning procedures, and professional, in-depth maintenance, the service life of titanium coils can be extended to over 1.5 times their designed value. The phased maintenance strategy provided in this guide can control O&M costs while ensuring stable operation in demanding environments such as chemical and offshore engineering, creating long-term value for your business.
