Maintenance & Service for Specialty
Non-Ferrous Plant Equipment
Specialty non-ferrous plant equipment, including heat exchangers and pressure vessels, operates under severe corrosive, thermal, and fouling conditions that affect long-term performance.
When degradation or failure occurs, effective maintenance based on material behavior and fabrication expertise is essential to restore reliability and extend service life.
With hands-on experience in specialty non-ferrous metals, ATX provides practical maintenance solutions, including repair, restoration, and on-site support.

Why ATX Maintenance & Service
35+ years of experience in plant maintenance and service
With extensive experience, we support maintenance and service for corrosion-sensitive plant equipment, including heat exchangers and pressure vessels. Our approach focuses on restoring performance and extending service life under real operating conditions.
Practical repair and on-site service capability
Maintenance and repair processes are carried out based on material behavior and fabrication knowledge. We provide practical solutions, including repair, restoration, and on-site support, tailored to actual plant conditions.
Inspection-based maintenance and compliance support
Inspection and testing are conducted to assess equipment condition and support maintenance decisions. Service work is carried out in accordance with project requirements, either in-house or through certified third-party agencies.
Materials We Work With
We work with a range of special metals selected based on corrosion conditions, temperature, and process requirements.
Ti Titanium
Widely used for seawater and high-salinity environments, offering stable corrosion resistance for heat exchanger applications.
Ta Tantalum
Used in highly corrosive chemical environments where conventional metals fail.
Capable of withstanding conditions such as 30% hydrochloric acid and 95% sulfuric acid at elevated temperatures.
Zr Zirconium
Provides superior corrosion resistance in oxidizing chemical environments, often used where titanium reaches its limits.
Nb Niobium
Enhances durability in high-temperature and aggressive chemical environments through stable oxide formation.
Ni Nickel
Maintains mechanical stability at elevated temperatures, with strong resistance in alkaline and reducing environments.
Inspection & Maintenance Scope
Inspection and maintenance activities are carried out based on project specifications and actual operating conditions.
Typical Maintenance Activities
- Tube condition inspection and corrosion assessment
- Detection of wall thinning, corrosion, and leakage in tubes
- Tube expansion condition check (joint integrity)
- Tube replacement and re-expansion work
- Leak detection and sealing repair
- Local repair and structural restoration
