Careers Understanding Pitting Corrosion
What is Pitting Corrosion?
Pitting corrosion is a localized form of corrosion that creates small holes or “pits” in metal surfaces. This type of corrosion is particularly dangerous because it can cause failure with little warning, leading to costly equipment damage and potential safety hazards.
Common Causes
- Chemical environment changes
- Chloride exposure
- Metal surface defects
- Stagnant conditions
Impact on Industry
- Equipment failure
- Production downtime
- Safety risks
- High replacement costs
HVTS: The Advanced Solution
High Velocity Thermal Spray (HVTS) technology offers a superior solution for preventing and addressing pitting corrosion in process vessels and boilers.
Key Benefits of HVTS
No Risk of Application Failure
HVTS does not experience failures that result from field welding or organic coating application by general contractors.
Total Asset Life Protection
HVTS offers lasting protection and does not require frequent reapplication. Application by highly-trained IGS technicians ensures that the cladding will be durable.
Peace of Mind & Technical Benefits
Each cladding is engineered for its intended environment. Inspections during normal operation are possible to verify integrity.
Commercial Benefits
HVTS delivers superior results at a fraction of the cost of vessel replacement or weld metal overlay.
Technical Features:
- No Dilution
- No Pre- or Post-Heat Treatment Required
- No Metal Distortion
- Fast Application (3 times faster than welding)
- High-Temperature Immersion Service over 500C / 932F
- Adhesion over 35 MPa
- No Environmental Controls During Application
- No Cure Time
- No Permeation
- No Pin Holes
